Missing Dividend Finder Answer Key

Learners determine the missing starting number (dividend) by analyzing how many times a number was subtracted. Students use repeated addition (or multiplication) to reconstruct the original amount, showing the inverse relationship between repeated subtraction and repeated addition. Each item displays the divisor and number of groups, prompting students to rebuild the dividend through repeated addition patterns. This activity strengthens conceptual understanding and prepares learners for algebraic thinking involving unknown values.
