C.U.B.E.S. Method: A systematic approach to solving word problems: Circle numbers, Underline the question, Box important words, Evaluate the steps, Solve and check.
- Model each step: Demonstrate the strategy while thinking aloud
- Practice together: Work through problems collaboratively
- Independent application: Allow students to use the strategy alone
- Reflection: Discuss which steps were most helpful
Sarah has 3 boxes × 8 markers per box = 24 markers total
She gives 5 markers away, so 24 - 5 = 19 markers left
If Sarah started with 24 and gave 5, she should have 19 left ✓
Sarah has 19 markers left after giving 5 to her friend
• Multiplication: Finding total in equal groups
• Subtraction: Taking away part of the whole
• Strategy: Using systematic approach to problem-solving
Read-Draw-Write Strategy: A three-step approach: Read the problem carefully, Draw a visual representation, Write the solution with steps.
4 tables × 6 students per table = 24 students total capacity
24 total - 3 absent = 21 students present
If 21 are present and 3 are absent, 21 + 3 = 24 total ✓
There are 21 students present in the class today
• Multiplication: Finding total capacity
• Subtraction: Accounting for absences
• Visualization: Drawing helps understanding
Step-by-Step Planning Strategy: Breaking down complex problems into smaller, manageable steps and solving each sequentially.
5 original shelves × 7 books per shelf = 35 books
2 new shelves × 6 books per shelf = 12 books
35 original + 12 added = 47 books total
5 × 7 + 2 × 6 = 35 + 12 = 47 ✓
There are 47 books in the store now
• Multiplication: Finding totals through repeated grouping
• Addition: Combining different amounts
• Planning: Breaking complex problems into steps
Multi-step word problem: A mathematical problem that requires more than one operation to solve, typically involving addition, subtraction, multiplication, or division in sequence.
Problem-solving strategy: A systematic approach to understanding and solving mathematical problems.
Key words: Words in problems that indicate which mathematical operation to use (e.g., "total" suggests addition).
- Model the strategy: Demonstrate each step explicitly
- Guided practice: Work through problems together
- Independent practice: Allow students to apply strategies alone
- Reflection: Discuss what worked and why
- Application: Connect to real-world scenarios
Multi-step word problem: A mathematical problem that requires students to perform multiple operations in sequence to find the solution. These problems often reflect real-life situations and require students to interpret language and translate it into mathematical operations.
Problem-solving strategy: A systematic approach that helps students understand, plan, and execute solutions to mathematical problems. These strategies provide a framework for approaching unfamiliar problems.
Metacognition: Thinking about thinking - students become aware of their own thought processes and problem-solving strategies.
Schema-based instruction: Teaching students to recognize problem types and apply appropriate solution strategies based on the problem's structure.
• Read thoroughly: Students must understand the entire problem before attempting to solve
• Identify key information: Extract numbers, operations, and relationships from the text
• Plan the sequence: Determine the order of operations needed to solve the problem
• Execute systematically: Follow the planned steps carefully
• Verify the solution: Check if the answer makes sense in the context of the problem
- Introduce the strategy: Explain the purpose and benefits of the problem-solving approach
- Model the process: Demonstrate each step while thinking aloud
- Guided practice: Work through problems together with student participation
- Collaborative practice: Have students work in pairs or small groups
- Independent application: Allow students to solve problems on their own
- Reflection and discussion: Review what strategies worked and why
- Transfer to new problems: Apply learned strategies to different problem types
C.U.B.E.S. for simple problems: Circle numbers (3, 4), Underline question, Box words like "total", Evaluate steps (addition), Solve
Read-Draw-Write for visual learners: Read problem → Draw representation → Write equation and solution
Step-by-step for complex problems: Break multi-operation problems into sequential steps
Questions & Answers
Question: Which problem-solving strategy is most effective for struggling readers who have difficulty with word problems?
Answer: For struggling readers, the Read-Draw-Write strategy is often most effective because:
- Visual representation bypasses some reading difficulties
- Pictures help clarify the problem situation
- Concrete representations make abstract concepts clearer
Additionally, consider supplementing with read-aloud accommodations and highlighting key information to support comprehension.
Question: How can I support my child in practicing these strategies at home?
Answer: Here are effective ways to support your child:
- Create real-world problems during daily activities (shopping, cooking, etc.)
- Practice one strategy consistently before introducing another
- Ask guiding questions: "What do you notice?" "What do you need to find?"
- Encourage your child to explain their thinking out loud
Remember to praise the process, not just the correct answer, to build problem-solving confidence.
Question: Why do we need special strategies for word problems? Can't I just guess?
Answer: Great question! Word problem strategies are important because:
- They help you understand what the problem is really asking
- They prevent you from mixing up numbers or operations
- They work for easy AND hard problems, so you'll use them as you grow
- Guessing might work sometimes, but strategies work every time
Think of strategies like training wheels - they help you learn to ride successfully every time!
