As we all know, spiral review is essential to our students' learning but can also be very difficult to include in our daily instruction. I have included 18 differentiated spiral review sheets. There are four different levels, five 1s, five 2s, five 3s, and three 4s. Each level has different problems involving comparing and rounding decimals, order of operations, exponents, adding and subtracting decimals, and word problems. I printed each level in a different color and then laminated them. The students use Vis-a-Vis expo markers to complete five problems per day. It's a quick check that has proven to be very beneficial in my classroom.
