Kara Root

This activity has 6 proofs that can be cut apart and assembled back together by students. I use it as an opening day activity for proofs after a brief introduction. It includes 3 algebra proofs and 3 geometry proofs. The geometry proofs are basic (no triangles). The answer key is the proof itself since they are typed out in order.

These place value strips can be printed off and used in front of the classroom or for a group of students. These help the students see that 1,289 is really 1,000 + 200 + 80 + 9. I print each place value on a different color of cardstock so that they can easily see the different place values. Check out the preview to see a picture of the one I printed for use in 4th grade.
