I would consider this an easy Integer worksheet, that would be great for early on when learning integers, homework, a beginning or end of year review sheet or substitute teacher work.
20 Problems -- 5 adding, 5 subtracting, 5 multiplication & 5 division
1 pdf containing 2 pages -- blank worksheet & answer key
Self Checking --- all the answers are in the butterfly. There are no repeat answers or 4 and -4 answers, to help reinforce the correct sign with the problem.
The butterfly is colored according to the problem numbers -- ie problems 1-5 are colored red, etc
If you find a problem, have a concern, etc -- Please let me know & i'll fix or explain.
