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 houses and other building in their Geo City (mapping and location skills). The Geo City also helps to broaden their horizons by giving them a sneak-peek into the world of architecture by constructing the buildings, and houses.
The Geo City will take weeks to construct, which will allow for a teacher to incorporate the Geo City into their teaching of geometric shapes and different geometric terms. Over the course of a few weeks of making the Geo City, the teacher can implement other facets of geometry that may help the students learn more about geometry.

Materials that will be needed for the Geo City are as follows: * Different types of empty packages from cereal boxes, oatmeal boxes, and cracker boxes in all sizes. * Tape, glue, markers, crayons and colored pencils. * Oak tag or Construction paper. * An empty stove or refrigerator box. * Geodot paper or Graph paper for each student. * A designated place for the Geo City to be erected.

Geometry Manipulatives

...Geometry Manipulatives MTH 157 April 6, 2015 Lynn Shevelenko Geometry Manipulatives I used 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 website is a great way for the kids to have an interactive experience...

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......

Pythagorean Quadratic Treasure Hunters

...Pythagorean Quadratic Treasure Hunters Pythagorean Quadratic Treasure Hunters Introduction to Algebra   Treasure Hunters Ahmed and Vanessa both have possession of one half of a complete treasure map. Ahmed’s map shows the treasure is buried in the desert 2x + 6 paces from Castle Rock. Vanessa’s map shows the treasure buried at x paces to the north and 2x + 4 paces to the east. When the two combine information, the location of the buried treasure is going to be a lot easier to find and they can share in the booty loot that they discover. Castle Rock is the lowest left point of the hypotenuse and at the bottom of the left leg and the treasure is at the furthest right point of the right leg. To factor the equation we start with the following, X2+(2x + 4)2 = (2x+6)2 Using the Pythagorean Theorem, a2+2ab+b2 i get a compound X2 +(4x216x+16)=4x2+24x+36 equation. It is then necessary to simplify using the quadratic 5x2+16x+16=4x2+24x+36 equation ax2-bx+c=0 so that I can factor. (x2+2)(x-10)=0 everything is set to zero for the zero factor X = 10 solve for x Plugging the x value for a, b, and c to the legs or the hypotenuse and what this does is it gives me the equation of how many paces it is to the treasure A= 10 B=2(10)+4 = 20+4 = 24 C=2x+6 = 2(10)+6 = 26 In conclusion, castle rock is located at the bottom left of a right hand triangle, and the treasure is 26 paces northeast of......

The Duho Mask

...Reginald Moore September 16, 2015 Art Appreciation The ‘Duho’ mask, which means hawk (or sometimes duha, meaning vulture) is a spiritual sculpture to encounter with spirits who materializes in animal form. In Bwa society, the identification and continued well-being of a family are often tied to a natural spirit. Upon consulting a priest, a family may commission a sculpture to embody that nature spirit. The masks appear at important funerals to honor the dead and escort their soul to the world beyond. The mask is the object of family pride and is an unofficial means of representing its prosperity and influence. This mask consists of many styles and paint mixtures. The wings of the primarily two-dimensional hawk mask are usually simply decorated with the paint. The face of the hawk has been reduced to basic geometric forms. A triangle defines the ‘face’ and contains a mouth and two sets of circles for eyes. The outwardly projecting beak and the hook at the top of the overall nature of this nature spirit representation. Bold geometric shapes repeated in brightly painted designs are often added to the surfaces of these relatively abstract forms. The hawk mask’s horizontal span extends about five feet wide; the wingspan of a related representation of the butterfly may be up to six or seven feet. The mask itself is a directional force because the length of the wings. It has gigantic circle going across the mask, which makes me look towards the beck and then the rest of......

Math and Me day. I guess you can say that this is where my love for math started. I am not saying that I never had to study or that I have never struggled with any math in my life, but for the most part, most of the math classes I have taken in my life have come pretty easily to me. I love when you are struggling with something in math and all of a sudden you have that a-ha moment where everything suddenly makes sense. In the past I have taken all the basics in math including Algebra and Geometry. However, these courses were also taken almost 20 years ago, and I have to admit that I am a bit rusty when it comes to all of the formulas and properties. Even though I may not remember all of the formulas, I still consider my previous courses a success. I may not remember the exact formula, but I do remember that the formulas exist and it is just a matter of looking the formula up and plugging in the right numbers to get the correct answer. For example, I remember how I used to love doing proofs in geometry, the longer the better. I probably could not jump right into one of those long proofs now, but I don’t think it would take me long to get back to being able to solve one. This is because math is always the same. It is not like English where the rules are always changing. Two plus two will always be four, and this is...

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......
