Problem Solving with Multiplication and DivisionActivities & Teaching Strategies
Active learning turns abstract multiplication and division problems into concrete challenges that build reasoning skills. Students move from reading words to visualizing actions, which strengthens their ability to choose operations and sequence steps accurately.
Learning Objectives
- 1Analyze multi-step word problems to identify the sequence of multiplication and division operations required for a solution.
- 2Construct mathematical models, such as equations or diagrams, to represent word problems involving both multiplication and division.
- 3Calculate the correct solution for multi-step word problems by accurately applying multiplication and division strategies.
- 4Evaluate the reasonableness of a solution to a multiplication and division word problem by comparing it to estimations.
- 5Critique alternative strategies for solving a multi-step word problem, explaining the efficiency and accuracy of each approach.

Pair Relay: Operation Sequences
Pairs read a multi-step word problem and solve the first operation together using counters. They pass the model to the next pair for the second operation, repeating until complete. Pairs then explain their full solution to the class.
Prepare & details
Analyze a word problem to determine the appropriate operation(s) to use.
Facilitation Tip: During Pair Relay: Operation Sequences, provide each pair with a problem strip and a blank strip to write the next step, ensuring they physically construct the sequence.
Setup: Groups at tables with access to source materials
Materials: Source material collection, Inquiry cycle worksheet, Question generation protocol, Findings presentation template
Small Group Bar Model Challenge
Provide groups with word problems printed on cards. Groups draw bar models to represent each step, solve using multiplication or division, and label units. Groups swap models to check and critique another group's work.
Prepare & details
Construct a mathematical model to represent a complex multiplication and division problem.
Facilitation Tip: For Small Group Bar Model Challenge, give groups colored markers to label each bar with the operation it represents, making thinking visible.
Setup: Groups at tables with access to source materials
Materials: Source material collection, Inquiry cycle worksheet, Question generation protocol, Findings presentation template
Whole Class Strategy Carousel
Display 4-5 multi-step problems around the room. Students rotate in groups, solving one per station with a chosen strategy and noting it. Final rotation allows groups to review and select the most efficient method.
Prepare & details
Critique different strategies for solving a multi-step problem.
Facilitation Tip: In Whole Class Strategy Carousel, post sample problems on large sheets so students can annotate with arrows and notes as they rotate.
Setup: Groups at tables with access to source materials
Materials: Source material collection, Inquiry cycle worksheet, Question generation protocol, Findings presentation template
Individual Model Builder
Students receive a word problem and build a personal model using paper strips or drawings. They solve independently, then pair up briefly to compare models and operations before sharing one with the class.
Prepare & details
Analyze a word problem to determine the appropriate operation(s) to use.
Facilitation Tip: Have Individual Model Builder students write a one-sentence justification under each diagram to connect their visual model to the problem’s story.
Setup: Groups at tables with access to source materials

Teaching This Topic
Teachers approach this topic by asking students to narrate the problem as a story before modeling it mathematically. They avoid rushing to equations, instead guiding students to draw quick sketches or arrays that match the language of sharing, grouping, or totaling. Research shows that students who verbalize before calculating make fewer order-of-operations errors and better connect symbols to real situations.
What to Expect
Students will confidently select operations based on context, model solutions using diagrams, and explain each step aloud. They will compare strategies with peers and adjust models until their answers match the problem’s conditions.
These activities are a starting point. A full mission is the experience.
- Complete facilitation script with teacher dialogue
- Printable student materials, ready for class
- Differentiation strategies for every learner
Watch Out for These Misconceptions
Common MisconceptionDuring Pair Relay: Operation Sequences, watch for students applying operations in a fixed order without reading context clues.
What to Teach Instead
Have pairs build their operation strips side by side, then read the problem aloud while pointing to each step in the strip to reveal why context dictates order.
Common MisconceptionDuring Small Group Bar Model Challenge, watch for students skipping remainders or ignoring them in final answers.
What to Teach Instead
Prompt groups to place actual counters on the remainder section of their bar model and discuss whether the extra items are shared or left over.
Common MisconceptionDuring Whole Class Strategy Carousel, watch for students reusing the same numbers across all steps without parsing unique values.
What to Teach Instead
Ask stations to highlight each number used in a different color and label which operation it belongs to before solving.
Assessment Ideas
After Pair Relay: Operation Sequences, give each student the same word problem to solve individually and explain how the operation order matched the story.
During Small Group Bar Model Challenge, circulate with a checklist to note which groups correctly labeled bars with operations and justified their models aloud.
After Whole Class Strategy Carousel, pose a problem and ask groups to share how their annotated strategies revealed the most efficient path to the answer.
Extensions & Scaffolding
- Challenge students finishing early to create a new multi-step problem for peers using the same numbers but different contexts.
- For students who struggle, provide problems with highlighted key numbers and step-by-step sentence starters.
- Deeper exploration: Ask students to design a pricing scenario where multiplication and division interact, then trade with a partner to solve.
Key Vocabulary
| Multi-step problem | A word problem that requires more than one mathematical operation to find the solution. |
| Dividend | The number that is being divided in a division problem. It is the total amount being shared or grouped. |
| Divisor | The number that divides the dividend. It represents the number of groups or the size of each group. |
| Quotient | The answer to a division problem. It tells how many times the divisor goes into the dividend. |
| Factor | A number that divides another number evenly. In multiplication, factors are the numbers being multiplied. |
