Multiplication and Division Word Problems

Inside the case file

Multiplication and division word problems for 3rd grade, in ten no prep CSI Mini Mystery Detective math worksheets with a carnival theme. These one step word problems cover equal groups, arrays, measurement, sharing and grouping. Use them as math activities for math centers, morning work, homework, early finishers and sub plans. You get an answer key for each case.

Use this pack when your class is working on multiplication and division together. Students decide which operation each problem needs, then match each answer to a suspect and cross that name off. Every page is self-checking, and every problem uses times table facts within 100.

When to Use This Resource

This pack fits best once your class knows what multiplication and division mean and is ready to use them in word problems. Every page mixes the two, and students read each problem and choose the operation themselves. The cases stand on their own and are all the same level. You can hand out one at a time, keep a few back for review before a test, or give the whole set to a strong group as extension work. It also works for guided math groups, bell ringers, test prep, homeschool and end of year review.

Grade Levels

Written for 3rd grade, with every fact up to 10 x 10 and every answer within 100. It also works as a quick multiplication and division review at the start of 4th grade.
