Students will learn how to divide numbers within 100 by one-digit numbers. They'll also learn how to use a known product to find an unknown quotient. For example, given \(8 \cdot 5 = 40,\) find \(40 \div 5.\) Students will solve both word problems and mathematical ones. Next, give your students this challenge. Finally, give them this one. The only prereq for both challenges is being able to divide within 100.

3.OA.C.7: Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division (e.g., knowing that 8 × 5 = 40, one knows 40 ÷ 5 = 8) or properties of operations. By the end of Grade 3, know from memory all products of two one-digit numbers.
