Product Description
One strategy for solving subtraction is by using an open number line. This document is in Word form, so the teacher may edit if desired.

I let students roll 2 or 3 dice (depending on how many digits you want them to work with) to generate their subtraction equation. They would then write the equation in the orange box and use the number line to show their work. They can use the adding up or removal strategy on the number line.
