Math3-5
Multi-Step Multiplication and Division Detective Practice
By Valerie S.
A detective-themed practice packet for 3rd graders that combines multiplication and division fact practice with real-world, two-operation word problems, including worked solutions. It builds fact fluency alongside multi-step reasoning, using the commutative, associative, and distributive properties as strategy tools.
Customize for your classroom
Teacher Guide & Tips
- Use as a 30-45 minute math block, starting with the Rulebook section as a short mini-lesson before students attempt the case problems independently or in pairs.
- Discussion question: How could the distributive property help you solve 7 × 8 if you already know 5 × 8 and 2 × 8?
- Scaffold for struggling readers: Read each word problem aloud together, underline the two operations needed, and let students use arrays or skip-counting before writing the equation.
- Extension for advanced students: Ask them to write their own two-operation case for a classmate, including a worked solution and a check of their answer.
- Estimated time: About 5 minutes for the mini-lesson and 25-35 minutes for the practice problems and worked-solution review.
