We are teaching several common core strategies to our third graders this year at my school, to help them add and subtract. One of those strategies is using an Open Number Line.

With no text books and little practice material, we are creating our own.
Here is a sheet we used to check student understanding after
our whole group instruction. (Clipart from 3am Teacher).
