Exploring Problem Solving StrategiesActivities & Teaching Strategies
Active learning turns abstract strategies into visible thinking. When students physically swap methods, hunt for patterns in teams, or explain their diagrams to peers, they move from hearing about problem-solving to experiencing how strategies shape solutions. This hands-on work makes strategy selection concrete rather than theoretical.
Learning Objectives
- 1Compare the effectiveness of working backwards, drawing diagrams, and looking for patterns for solving specific multi-step word problems.
- 2Design a step-by-step problem-solving plan for a given multi-step word problem.
- 3Justify the choice of a particular problem-solving strategy for a specific mathematical challenge.
- 4Create a new word problem that can be effectively solved using the 'look for a pattern' strategy.

Pairs Challenge: Strategy Swap
Pairs solve the same multi-step word problem using different strategies, such as one drawing a diagram and the other working backwards. They swap papers after 10 minutes, explain the approach used, and evaluate its strengths. Discuss as a class which worked best and why.
Prepare & details
Compare the effectiveness of different problem-solving strategies for a given problem.
Facilitation Tip: During the Pairs Challenge, provide a one-minute timer after each swap so students focus on articulating the method’s strengths, not just solving.
Setup: Groups at tables with problem materials
Materials: Problem packet, Role cards (facilitator, recorder, timekeeper, reporter), Problem-solving protocol sheet, Solution evaluation rubric
Small Groups: Pattern Hunt Relay
Divide a sheet of pattern-based problems among group members. Each solves one using a chosen strategy, passes to the next for verification and pattern extension. Groups race to complete and justify their full solutions.
Prepare & details
Design a step-by-step approach to solve a multi-step word problem.
Facilitation Tip: For the Pattern Hunt Relay, give each group a different colored marker to track their steps, making progress visible for quick checks.
Setup: Groups at tables with problem materials
Materials: Problem packet, Role cards (facilitator, recorder, timekeeper, reporter), Problem-solving protocol sheet, Solution evaluation rubric
Whole Class: Diagram Gallery Walk
Students create posters showing diagrams for various problems. Display around the room. Class walks, notes strategies, and votes on most effective visuals. Debrief on when diagrams outperform other methods.
Prepare & details
Justify the choice of a particular strategy for a specific mathematical challenge.
Facilitation Tip: In the Diagram Gallery Walk, ask students to carry a sticky note to jot down one question or observation per diagram to spark discussion.
Setup: Groups at tables with problem materials
Materials: Problem packet, Role cards (facilitator, recorder, timekeeper, reporter), Problem-solving protocol sheet, Solution evaluation rubric
Individual: Strategy Journal
Students tackle three problems solo, recording strategies tried, successes, and adjustments. Share one entry with a partner for feedback. Compile class insights on versatile strategies.
Prepare & details
Compare the effectiveness of different problem-solving strategies for a given problem.
Facilitation Tip: During Strategy Journal time, model how to write a clear justification by thinking aloud with a sample problem first.

Teaching This Topic
Teach strategies in short, focused bursts followed by immediate application. Avoid overwhelming students with too many methods at once; introduce one per lesson with guided practice. Emphasize that no single strategy is superior—context determines fit. Use anchor charts with visual examples to reinforce when to use each method. Research shows that students benefit from comparing strategies side-by-side, which builds metacognition and flexible thinking.
What to Expect
Students will confidently choose appropriate strategies, justify their choices, and compare effectiveness across problems. They will recognize when a diagram clarifies relationships, patterns reveal sequences, or working backwards untangles unknowns. Clear reasoning and flexibility in method use signal successful learning.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring Pairs Challenge: Strategy Swap, watch for students who treat the activity as a race to finish rather than a chance to compare method efficiency.
What to Teach Instead
Structure the one-minute swaps with a focus question: 'What made this strategy work well for this problem?' Collect responses and discuss as a class after each round.
Common MisconceptionDuring Small Groups: Pattern Hunt Relay, watch for students who search randomly without recording steps, assuming patterns will reveal themselves.
What to Teach Instead
Provide a template with columns for observations, predicted next steps, and justification. Require groups to fill one row before moving to the next station.
Common MisconceptionDuring Whole Class: Diagram Gallery Walk, watch for students who assume diagrams only belong in geometry or spatial tasks.
What to Teach Instead
Label each station with a word problem context (e.g., sharing items, scheduling tasks). After viewing, ask students to redraw one diagram for a new context to reinforce versatility.
Assessment Ideas
After Pairs Challenge: Strategy Swap, present two new word problems. Ask students to write down which strategy they would use for each and one reason why, using their notes from the swaps.
After Individual: Strategy Journal, give students a multi-step word problem. On their exit ticket, they should show their chosen strategy, the steps, and write one sentence explaining why their strategy fit the problem well.
During Small Groups: Pattern Hunt Relay, pose a complex word problem. Ask groups to discuss: 'What are two strategies we could use? How would the steps differ? Which seems more efficient and why?' Circulate and listen for reasoning about context.
Extensions & Scaffolding
- Challenge early finishers to create a new word problem where their strategy is the most efficient, then trade with a peer for solving.
- Scaffolding: Provide partially completed diagrams or scaffolded prompts with blanks for key steps in working backwards.
- Deeper exploration: Ask students to design a flowchart that guides peers in choosing a strategy based on problem features.
Key Vocabulary
| Working Backwards | A strategy where you start with the final answer and reverse the steps to find the initial value or unknown. |
| Drawing Diagrams | A strategy that involves visually representing the problem using pictures, charts, or graphs to understand relationships and find solutions. |
| Looking for Patterns | A strategy where you identify repeating sequences or relationships within the data of a problem to predict or solve for unknowns. |
| Multi-step Word Problem | A mathematical problem that requires more than one operation or logical step to find the solution. |
Suggested Methodologies
