There is a page for each of the following facts...
+0, +1, +2, +3, +4, +5, +6, +7, +8, +9, +10, +11, +12
Included is an answer key with and without a grading percentage key.

I used these pages as a transition between recess and settling back to class –
IT WORKED SO GOOD!
I used them for a timed fluency test, with a 90 second timer.
