*What are the key ideas of geometry that you want your students to work through during the school year?*

Depending on the grade level, the key ideas that I would want my students to know would vary. I am currently working with 1^{st} graders for my field experience, so I will focus on this level. I would first want my students to be able to distinguish between different shapes and their attributes to know the shapes. I would want my students to work through constructing shapes. I would lastly want my students to work through recognizing similar shapes.

*How would you structure this lesson for students in an elementary classroom? *

When teaching this type of lesson in the classroom, I would first start by getting students thinking about triangles. I would teach students that a triangle is a three-sided figure that is closed. I would remind students that triangles can come in several shapes and sizes and can have different lengths in sides. I would do just as the video said and have students look around the room to find triangles. I would then have students practice making triangles with the geoboard as I call out different types of triangles.

**Do you think this activity would be appropriate for second grade and under?**

*What parts did you have issues with? Did you need to revisit some vocabulary words to remind yourself of their meanings? If so, which ones?*

I did not have any issues with the geoboard paper. However, I could not figure out why I couldn’t make an equilateral triangle until finishing the PowerPoint. Vocabulary was still fresh in my brain.

**How was your vocabulary remembering?**

*Further Discussion*

In terms of my own personal rating, I would say that van Hiele would say I was at the deduction level. With this being said, I am able to classify shapes regarding theirs sides and attributes. It is easy for me to prove why a shape is a shape by explanation. I would say that van Hiele’s levels would change when considering 2D or 3D shapes. This is because the dimensions will bring forth a different perspective. However, I think that I would remain on the same level personally. This would fluctuate from child to child within the classroom.

Amy,

For this lesson I think that it could be used for grades under 2nd, but only 1st. I do not think that Kindergarteners would get the full understanding, but I think that you would be able to simplify and adjust the lesson to make it appropriate for the grades. I feel that each grade needs to work on a foundation or level of geometry. For me I remembered all of the vocabulary words for this module. I think that is because I have a lot of experience with math and have been doing it for a very long time. My concentration is in mathematics, so I have been continuing and growing in math in a variety of ways. Overall, I think this module was a great way to see how we should create lessons in math and to show the levels at which are students are at. I think that with every topic in math there are levels that the students are at.
