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.
