Build It Back Up

This worksheet asks students to determine the missing starting number (dividend) by using repeated addition or multiplication. Each problem shows a divisor and quotient, and learners must rebuild the dividend by adding the divisor repeatedly until the total matches the missing starting number. The worksheet models this process with guiding “Think:” statements that scaffold students’ reasoning and show how equal groups accumulate. This develops a strong understanding of the inverse relationship between repeated subtraction and repeated addition. Students strengthen algebraic thinking, pattern recognition, and number sense as they reconstruct the full value. The format supports computation accuracy and reinforces that division, multiplication, and repeated addition are interconnected.
