Geometry Manipulatives
I used www.geogebra.org and I used it to manipulate the shapes and I used it to create shapes as well. These tools are great, I think I can see being able to use them in the classroom setting I think that this tool will be something that is very helpful for students to learn how to create shapes and how to turn one shape into another. I will use this tool to have them make a shape and then have one of the other students take that shape and turn it into another shape. I would also have them do this in a setting without the tool, I would have one student draw a shape, and then have another student use their pencil to change the shape by using a different color pencil and have it go around the circle to see how many shapes they could make with the one starting shape. With little kids I feel that it is important to have as many interactive activities as possible just because it is a fun way for them to learn, and I think that it would be a good way for them to remember the activity and remember how they did what they did with the coloring in groups. Group activities are also a fun way for kids to learn. It is another interactive way for students to learn as well as get some energy out of their systems so that way recess is not the only time the get to run around and get their energy out. I think that the www.geogebra.org website is a great way for the kids to have an interactive experience. You are able to use it to create your own shapes as well as use premade shapes to change into other shapes and learn how to change shapes. For students to learn shapes is important for their foundation, and this website, to me, is a great tool for them to be able to do that as well as have some fun while learning. Learning should be fun, if you are not having fun while learning, then I feel…...

Fractal Geometry

...Dr. Muhammad Maqbool MAT 121, Research Project 2 January 29, 2008 Fractal Geometry A fractal is generally “a rough or fragmented geometric shape that can be subdivided into parts.” One of the ways that fractal geometry is used is in the area of medicine. In the past few years fractal analysis techniques have gained increasing attention in signal and image processing, especially in medical sciences such as Pathology. Fractal analysis has found applications in the detection of coding regions in DNA and measurement of the space-filling properties of tumors, blood vessels and neurons. Fractal concepts have also been usefully incorporated into models of biological processes, including cell growth, blood vessel growth, periodontal disease and viral infections. Other very interesting applications are founded in medical imaging Fractal analysis is widely used in image processing, both in characterizing shapes of objects and in assessing texture. Breast masses present shape and texture characteristics that vary between benign masses and malignant tumors in mammograms. Limited studies have been conducted on the application of fractal analysis specifically for classifying breast masses. The fractal dimension of the contour of a mass may be computed either directly from the two dimensional contour or from one-dimensional signatures derived from the contour. Other ways that fractal geometry is use is in biology with different applications and techniques use to classify and...

Geometry

...Geometry Geometry is all about shapes and their properties. If you like playing with objects, or like drawing, then geometry is for you! Geometry can be divided into: Plane Geometry is about flat shapes like lines, circles and triangles ... shapes that can be drawn on a piece of paper Solid Geometry is about three dimensional objects like cubes, prisms and pyramids. Plane Geometry Plane geometry is all about shapes like lines, circles and triangles ... shapes that can be drawn on a flat surface called a Plane (it is like on an endless piece of paper). Plane A plane is a flat surface with no thickness. Our world has three dimensions, but there are only two dimensions on a plane. Examples: • • length and height, or x and y And it goes on forever. Examples It is actually hard to give a real example! When we draw something on a flat piece of paper we are drawing on a plane ... ... except that the paper itself is not a plane, because it has thickness! And it should extend forever, too. So the very top of a perfect piece of paper that goes on forever is the right idea! Also, the top of a table, the floor and a whiteboard are all like a plane. Imagine Imagine you lived in a two-dimensional world. You could travel around, visit friends, but nothing in your world would have height. You could measure distances and angles. You could travel fast or slow. You could go forward, backwards or sideways. You could move in straight lines, circles, or anything so......

Making Geometry Fun

...Making Geometry Fun with Origami Lucila Cardenas Vega University of Texas at Brownsville Introduction Teachers must have an understanding of students’ mathematical thinking in order to create meaningful learning opportunities. This becomes more relevant when teaching subjects that not all students have an interest for, such as, geometry. Since geometry is the study of shapes and configurations, it is important to understand how a student thinks about the different properties in geometry including, symmetry, congruence, lines and angles. Students remember a lesson better and the information becomes more significant when learning is accessed through hands on activities. (Pearl, 2008). Origami is the art of transforming a flat sheet of material into a finished sculpture through folding and sculpting techniques. The use of origami can be thought of as art; however, there are so many other benefits of incorporating origami in geometry lessons. According to experts, origami teaches students how to follow directions, encourages cooperation among students, improves motor skills and it helps develop multi-cultural awareness (Weirhem, 2005). Origami activities used in geometry lessons reinforces vocabulary words, facilitates the identification of shapes and simplifies congruency and symmetry (Pearl, 2008). In origami, students take a flat piece of paper and create a figure that is three dimensional. The use of origami in geometry is not new. Friedrich Froebel, the......

According to "Geometry Standard" (2013),”They will be able to recognize, and name two dimensional shapes, as well as describing the attributes as well as the parts of two and three dimensional shapes.” They also will be able to show the locations as well as the spatial relationships by using coordinate geometry and other representational systems. According to "Geometry Standard" (2013)”They will be able to show, name and interpret relative positions in space, and apply ideas about relative position.” They are definitely going to be able to apply the different transformations and they will also be able to use symmetry to discover mathematical situations.” “They will be able to recognize and know the different sides, flips as well as the turns. ("Geometry Standard", 2013). Lastly they be able to use visualization, and modeling to solve problems. “They will be able to recognize geometric shapes in their environment and can show their location.” ("Geometry Standard", 2013). With this activity and game I believe that my students will learn geometric shapes in a fun and exciting way, because they will not realize they are learning, but they will think that they are having fun. I also believe that students with learning problems can benefit as well, because they will be in small groups, and will be able to feed off each other. Geometry Standard. (2013).

History of Geometry

...History of Geometry Geometry was thoroughly organized in about 300 BC, when the Greek mathematician Euclid gathered what was known at the time, added original work of his own, and arranged 465 propositions into 13 books, called 'Elements'. The books covered not only plane and solid geometry but also much of what is now known as algebra, trigonometry, and advanced arithmetic.  Through the ages, the propositions have been rearranged, and many of the proofs are different, but the basic idea presented in the 'Elements' has not changed. In the work facts are not just cataloged but are developed in a fashionable way. Even in 300 BC, geometry was recognized to be not just for mathematicians. Anyone can benefit from the basic learning of geometry, which is how to follow lines of reasoning, how to say precisely what is intended, and especially how to prove basic concepts by following these lines of reasoning. Taking a course in geometry is beneficial for all students, who will find that learning to reason and prove convincingly is necessary for every profession. It is true that not everyone must prove things, but everyone is exposed to proof. Politicians, advertisers, and many other people try to offer convincing arguments. Anyone who cannot tell a good proof from a bad one may easily be persuaded in the wrong direction. Geometry provides a simplified universe, where points and lines obey believable rules and where conclusions are easily verified. By first studying how to reason......

Islamic Architecture and Geometry

...Islamic Architecture and Geometry When studying Islamic architecture and archaeology one can easily become distracted by the beauty and grace of the many different and Iconic Islamic structures. Coming from New York City it is becoming increasingly difficult to learn about the cities past by studying its Architectural history. Everyday older buildings are being knocked down and replaced by newer and more visually appealing skyscrapers. However, this trend has not come to pass in the major Islamic cities of the east. From Damascus to Baghdad or Jerusalem or Samara one can study and see the history that is still currently present within their cities. One of the most fascinating aspects of Islamic architecture and archaeology for me has always been the immense attention to detail in which the Islamic monuments were built with. For example Ludovico Micara talks about the importance of Geometry within the context of Islamic architecture and design. He references the well-known historian of Islamic art Oleg Grabar. Grabar talks about how writing, geometry, architecture and nature go hand in hand within Islam “In viewers well-defined emotions and stances: control and forcefulness of assertion with writing, Order with geometry, boundaries and protection with architecture, life forces with nature and throughout sensory pleasure”, This concept of interweaving architecture and design with geometry and nature has always been the most interesting concept for me when studying......

...given by ((b-2b)/(2a-a)). Which equals (-b/a). 9. The slope of segment EH is given by ((0-b)/(a-0)). Which equals (-b/a). 10. The slopes of segments FG and EH are equal, so the lines are parallel to each other. 11. The slope of segment FE is given by ((2b-b)/(a-0)). Which equals (b/a). 12. The slope of segment GH is given by ((b-0)/(2a-a). Which equals (b/a). 13. The slopes of FE and GH are equals so these two segments are parallel to each other. 14. By definition, a four sided figure with two set of opposite parallel sides is a parallelogram. Figure EFGH is a parallelogram. Part D The synthetic technique requires someone to know and understand geometric postulates. Someone with limited knowledge of geometry would find it difficult, if not impossible to proof figure EFGH is a parallelogram using synthetic techniques. However synthetic techniques are useful when you don’t have the luxury of a grid and coordinate system. The analytic technique is much more straight forward. You have two line segments and the endpoints have coordinates (x,y). Take the difference of the y-coordinates and divide by the difference in the x-coordinates and you have the slope of the line. If those slopes are equal, then the lines are parallel. With the analytical technique, you take the information you have and formulate your proof. The analytic technique is straight forward. The disadvantage to the analytical technique is that it requires you to have......

Alternatives to Euclidean Geometry

... Alternatives to Euclidean Geometry Student name: Institution: Alternatives to Euclidean Geometry According to Johnson (2013) Euclidean Geometry , commonly known as high school geometry, is a mathematical study of geometry based on undefined terms such as points, lines and or planes; definitions and other theories of a mathematician known as Euclid (330 B.C.) While a number of Euclid’s research findings had been earlier stated by Greek Mathematicians, Euclid has received a lot of recognition for developing the very first comprehensive deductive systems. Euclid’s approach to mathematical geometry involved providing all the theorems from a finite number of axioms (postulates). Euclidean Geometry is basically a study of flat surfaces. Geometrical concepts can easily be illustrated by drawings on a chalkboard or a piece of paper. A number of concepts are known in a flat surface. These concepts include, the shortest distance between points, which is known to be one unique straight line, the angle sum of a triangle, which adds up to 180 degrees and the concept of perpendicular to any line.( Johnson, 2013, p.45) In his text, Mr. Euclid detailed his fifth axiom, the famous parallel axiom, in this manner: If a straight line traversing any two straight lines forms interior angles on one side less than two right angles, the two straight lines, if indefinitely extrapolated, will meet on that same side where the angles smaller than the two right angles.

Geometry Manipulative

...Geometry Manipulative Handout Joan L. Holyfield Math/157 March 8, 2015 Instructor: James Paga Geometry Manipulative Handout The geometry manipulative that I chose to present is how to make a Geo City. With making a Geo City, it teaches students in grades 3-5. This math exercise encompasses learning and identifying cubes, pyramids, cones, rectangular and other shapes in different sizes which are appropriate for this age group. This activity can be done in a group setting, with each child having a share in identifying different geometrical shapes, and putting them in a real-world setting. By using these different geometric shapes to construct buildings and cars, the children will learn about spatial visualization, location and coordinate points, and transformation. The Geo City will help to reinforce the relationships with two and three-dimensional shapes that have already been learned in previous classes. The students will also be able to explore the effects of rotating, reflecting, and transforming shapes. The Geo city also lends itself to real world application by simulating a city block that they may find in their neighborhood. Then they can begin to understand how the geometric shapes are a part of their everyday lives. Constructing the Geo City also helps the children with their mapping and graph skills, because they will be using both to first, decide how to design the city (using graph paper or geo dot paper), then by deciding where to put the......

Iago a Manipulative Villian

...In Shakespeare's play Othello,the charecter Iago is a mutilayered,deceptive,and manipulative villian;causeing mishaps to other characters for revenge.Iago uses his stratigec acts of manipulation to undermine the charecters weakness.He exploits Rodrigo love for Desdemona,the friendship between him and Cassio,and toys with Othello's mind by playing on his self-doubt. Thus, giving Iago the advange to use their weaknesses against them. First Iago uses Rodrigo's naive and gulliable personality to own adavantage.Roderigo's obession with Desdemona renders him susceptible to Iagos manipulation. this obsession causes him to believe anything Iago says to hope in getting Desdemona.Iago convinces Rodrigo that the jewels will be given to Desdemona as a proclamationof his love when acatually,Iago claims to to himself.Iago takes advantage of Rorego for his money.Later in the play,Iago uses Roderigo and conveience him to kill Cassio. Rodergo then says "i have no great devotion to the deed and yet he hath given my satisfying reasons 'Tis but a man gone. forth,my sword:he dies" (V.i.8-10). Roderigo then attempts to kill Cassio but in the play Iago says"i have rubbed this young quat almost to the sense and he grows angry, May unfold me to him there stand i in much peril. No, he must die."(V.i. 11-23) this shows how Iago takes advantage of foolish Rodrigofor his own needs and once his value is used up.Overall Rodrigo was drawn in Iago's schemes due to his love for Desdemona.

History of Geometry

...The History of Geometry Geometry, from the ancient Greek “geo” meaning Earth and “metron” meaning measurement, arose as the field of knowledge dealing with spatial relationships. Geometry was revolutionized by Euclid, who introduced mathematical rigor still in use today. In modern times, geometric concepts have been generalized to a high level of abstraction and complexity, and have been subjected to the methods of calculus and abstract algebra, so that many modern branches of the field are barely recognizable as the descendants of early geometry. The earliest recorded beginnings of geometry can be traced to early peoples, who discovered obtuse triangles in the ancient Indus Valley, and ancient Babylonia from around 3000 BC. Early geometry was a collection of empirically discovered principles concerning lengths, angles, areas, and volumes, which were developed to meet some practical need in surveying, construction, astronomy, and various crafts. Among these were some surprisingly sophisticated principles, and a modern mathematician might be hard put to derive some of them without the use of calculus. Greek Geometry The early history of Greek geometry is unclear, because no original sources of information remain and all of our knowledge is from secondary sources written many years after the early period. For the ancient Greek mathematicians, geometry was the crown jewel of their sciences, reaching a completeness and perfection of methodology that no other branch of......

Analytic Geometry

...Analytic Geometry is a branch of mathematics in which problems are solved using the principles of Geometry and the processes of Algebra. He is regarded as the founder of Analytic geometry by introducing coordinates system in 1637. René Descartes The Cartesian Coordinate System * also known as Rectangular Coordinate System or xy-Coordinate System. * It is made up of two mutually perpendicular number lines with the same unit of length and intersecting at their origin. The origin of its number line is its zero point. * The number lines are called the coordinate axes. * The horizontal line is called the x-axis and the vertical line is called the y-axis. * The coordinate axes divide the whole plane into four regions called quadrants. * The plane on which these axis are constructed is called the Coordinate Plane or xy-plane. * The distance of any point P from the y-axis is called x-coordinate or abscissa of the point P. * The distance of any point P from the x-axis is called the y-coordinate or ordinate of the point P. * The pair of real numbers (x,y) is called the coordinate pair of point P. * The symbol P(x,y) is used to indicate the point P on the plane with abscissa x and ordinate y. * The signs of the coordinates determine the quadrant where the point lies. * QI: (+,+) QIII: (-,-) QII: (-,+) QIV: (+,-) Exercise 1.1 Indicate the quadrant or the axis on which the point lies. 1.

Geometry

...The word geometry is Greek for geos - meaning earth andmetron - meaning measure. Geometry was extremely important to ancient societies and was used for surveying, astronomy, navigation, and building. Geometry, as we know it is actually known as Euclidean geometry which was written well over 2000 years ago in Ancient Greece by Euclid, Pythagoras, Thales, Plato and Aristotle just to mention a few. The most fascinating and accurate geometry text was written by Euclid, and was called Elements. Euclid's text has been used for over 2000 years! Geometry is the study of angles and triangles, perimeter, area and volume. It differs from algebra in that one develops a logical structure where mathematical relationships are proved and applied. In part 1, you will learn about the basic terms associated with Geometry. Terms (Undefined) 1. Point Points show position. A point is shown by one capital letter. In the example below, A, B, and C are all points. Notice that points are on the line. 2. Line A line is infinite and straight. If you look at the picture above,  is a line,  is also a line and  is a line. A line is identified when you name two points on the line and draw a line over the letters. A line is a set of continuous points that extend indefintely in either of its direction. Lines are also named with lowercase letters or a single loswer case letter. For instance, I could name one of the lines above simply by indicating an e. Terms (Defined) 1. Line Segment A......
