TEDU 411 – Week 11 – Art Activity

Here is a link and a picture of the 3d project I thought I would create for class. It is a cube with the different early Americas explorers on each side, along with a free pick side. The idea is to have students roll or gently toss the cube to one another and whatever side it lands on, they have to talk about what they know about the explorer they landed on.

TEDU 411 – Week 9 – Blog Post

“Fish” (1964) by M.C. Escher

This week’s chapter in the book focused on integrating the arts into mathematics in the classroom, and our task was to find one piece of art, of any medium, that could be used to teach a math concept in class. I chose to use one of M.C. Escher’s paintings. This piece, a picture of fish, two different colored fish, ordered together in one large, repeating pattern, could be used to help teach several concepts in mathematics to elementary school students. For younger students in grades K-3, it could be used to help students understand the idea of patterns. With a visual like this, they could see how patterns are formed not only with colors, but with shapes as well and that some patterns may have a combination of various different aspects that all come together to make it a cohesive piece. For older students in grades 4-6, this piece could be used to talk about tessellations, which is basically using shapes repeatedly to create a pattern without any gaps. They could use this picture as a starting point to talk about tessellations and what the concept entails with a more relateable approach than simply throwing shapes mashed together at them. Everyone can see the fish and may be able to more easily recognize it is in a pattern thanks to its details than normal shapes would allow for. This Escher piece, and many of his other works, can be used in a variety of different mathematical concepts, these were just a two that really stood out to me.

Math 303 – Geometer’s SketchPad in the Classroom


Creating Carnival Tickets with the Geometer’s Sketchpad

Using Translations, Tessellations, and Quadrilaterals


1. First construct a line segment, we’ll call it AB. Make sure to label the points, A and B.

2. Create a point somewhere above AB and label it C.

3. Mark AB as a vector, by selecting it, clicking on the  transform tool, and selecting mark as vector, then select point C.

4. With point C selected, use the transform option to translate AB with point C.

5. With the translation in place, close off the rest of the polygon for a parallelogram like figure.

6. Use the line segment tool to create multiple little segments from point A to C, much like a torn section of paper.

7. Making sure that AB is still the marked vector, select all the little line segments from the previous step and translate them.

8. Select all the vertices of the shape and use the construct tool to fill in the interior. Use any color you’d like.

9. Keep AB as your vector and then select the interior of the shape.

10. Translate the shape. And repeat this, by selecting the newly created shape each time, until they disappear off of the page.

11. Then make BA your new vector and repeat the translating with the colored interior.

12. Make sure that each alternating shape is a different color.

13. Using the Polygon Edge tool, create another parallelogram within the first one. This does not have to be perfect. Do this for each of the shapes your created while tessellating.

14. Make sure that the new shapes are not the same color as the first ones and then use your text tool to make up any kind of ticket information you’d like. (Optional, hide any unwanted lines and vertices from the original shape)

And voila, there is your finished line of carnival tickets.


A. How has the program allowed you to explore geometry in the classroom this semester?

With the use of Geometer’s Sketchpad, I have been able to understand the concepts that we have covered in class on a more in depth level. I have been able to not only review ideas that we have gone over in class, but also gotten hands on experience with working with these various concepts thanks to the assignments we have been given for the program. Aside from what was covered in class, simply being able to work on my own and look at all the different tools in the program has introduced me to more geometric concepts. I have been able to look more at what makes a polygon and how they can vary in shape and size, not just be regular. And working with polygons more is just one of the things I have had the chance to explore with GSP. I hope to continue using it to learn and understand more about geometry as a whole.

B. What are the uses of the program in your future classroom?

The uses of this program in my own future classroom will be many and varied. I can use it as a way to introduce basic shapes, teach about angles and measurements, how to work with rigid motions, and a number of different things. Most of which will probably be in class demonstrations followed by students replicating their own versions of the assignments. I hope that it will be a hands on tool that will not only help to teach students further about geometry, in all different grade levels, but also help to keep them interested in the subject as a whole.

C. What are the strengths and/or weaknesses of the program?

The strengths of this program definitely lie within how it offers more hands on experience for students to be able to work with concepts that, at times, can be very confusing. They are able to try an assignment and work with a geometric concept at their own pace with their own thought processes and hands. Its weaknesses, however, are that it can be rather confusing, especially to start with. Students need to have very clear instructions to be able to properly use the tools that the program offers and work with the concepts, at least until they have become more accustomed to it. A different format for the program with more clearly labelled tools would definitely not hurt it, particularly for younger students who may be using it. But with both its goods and bads, I would definitely suggest it for anyone learning or teaching geometry to use GSP.
