This is a COMPLETE set of Timed Subtraction Facts tests. Each test has 30 problems which are to be completed in 3 minutes. These subtraction tests are for number -0 through -20. They also spiral so when they are testing over -10's they may have some problems that they have previously mastered.
This set is a great set to add on to the Timed Addition tests that I also have in my store.
I hope you enjoy these! I have seen my students really grasp their math facts when doing Timed Tests.
