A great way for students to practice their rounding and estimation skills! Students estimate the sum in the first box, then find the actual answer in the second box, then find the difference of their estimate vs. their actual answer in the 3rd box. There are 2 sides to this sheet and the every last problem is a **bonus** problem with a sum well into the hundreds. Also, check out my Excellent Estimation with Subtraction!
