Videos are a great way to get students to think.  Good ones keep students engaged and teach. Here is a great video about triangles by Grover and Rita.  It’s funny, well-done and pushes on students’ narrow conceptions of geometric shapes.  It is a great springboard into a discussion about attributes!

Grover and Rita present triangles.

Here is also a great song about triangles (more upper elementary).

Pattern Blocks: Great tools for guided math and math centers

Geometry is the only domain that spans k-8!  There are so many ways to use them across the grade levels.  Here are some great links to templates, with many different suggested activities.  I also really like to ask students to complete the puzzles with different pieces so they have to focus on composing and decomposing shapes. Students can do these activities in guided math groups with the teacher watching and questioning, or do them in centers for practice. Be sure to have the students use the correct vocabulary and to describe the math to the teacher and to their math partners.

Quick Geometry Images: Guided Math and Whole Class Routines to Build Geometric Thinking

Geometry is the only Domain that goes from k-8.  It it crucial that we develop geometric thinking throughout the k-8 curriculum so that students have a strong foundation for high school.   One activity that I find quite intriguing, but that I don’t see done much is the idea of quick geometry image routines.  In these routines, you show students quick images (pictures of 2d and 3d shapes) and then you have them quickly sketch out those images.  Sometimes, you just say a shape and the students quickly draw it.  It is important to have students to picture the image in their mind and then picture it on paper in order to develop their geometric reasoning.

Here are some sources for quick images:

The hierarchy of quadrilaterals is quite confusing for students.  Here is a great unit that has several hands on activities so that students begin to own this knowledge.  Remember that building geometric thinking is something that takes place all year long.  Talk about shapes during your weekly math conversations.  Have geometry “do nows” woven throughout your week.  Incorporate talks about shapes throughout your routines. I especially like the foldable books that they have integrated into the unit.  I would have the students do these and glue them in their math journals.
