I staple these basic math strategy posters up to a bulletin board in my classroom so that students can refer to them as needed. A fellow co-worker used the photocopier and made two posters fit on one page and gave each of her students a book of the strategy posters.
The strategies are from the Origo Math Program.
The Subtraction Posters include:
* Count Back
* Find the Difference
* Think of Addition Facts
* Make Ten (2 to choose from)
