Can your young mathematicians find any sum of two numbers? Challenge them with three! This addition practice sheet includes two pages of equations, all of which have learners finding the sum of three 3-digit numbers. Sums are all below 1000. There are sixteen questions on each page, and answers are provided. Because there aren't example problems, you will definitely want to model this and check for understanding first.
