This activity contains four pages of 100 problems including basic addition, subtraction, multiplication, and division of integers. Just like the 100 problem time tests given to grade school students, this sheet can serve multiple purposes when trying to get students to master the integer operation rules. Time your students to see how long it takes them; set a timer to see how far they can get in a set amount of time; or have students race each other! This is great for students just learning integer rules or for students that need a refresher!
