Great for Centers!
Being able to quickly recall basic addition and subtraction facts is an important skill. Give students the opportunity to practice solving these facts in a fun and challenging way!
There are 20 puzzles included (10 addition and 10 subtraction). Each puzzles focuses on a different skill (+1,+2, etc.) Facts go up to 10+10 and 20-10.
Students must match ALL sides of the puzzles to put together correctly. They are able to get help or check their work because the completed puzzle makes a picture.
I have made a grayscale and colored version :-)
