Students rely on keywords like "altogether" = add, "left" = subtract. But keywords can be misleading! "Maria has 3 times as many as her brother" uses "times" but isn't always straightforward multiplication.
Teach students to visualize the story first. Ask: "What's happening? What do we know? What do we need to find?" Draw pictures or act it out before choosing an operation.
In two-step problems, students may perform operations in the wrong order (e.g., adding before multiplying when they should multiply first).
Break the problem into parts. Ask: "What do we need to find FIRST before we can answer the final question?" Use step numbers: Step 1, Step 2.
Students calculate without checking if the answer makes sense. They might say "I have 500 cookies left" when the problem started with only 24 cookies.
Always ask: "Does this answer make sense? Is it too big? Too small?" Estimate first, then solve. Compare the answer to the estimate.
Teach the CUBES strategy or similar framework: Circle the numbers, Underline the question, Box key words, Evaluate what steps to take, Solve and check.
"When we solve word problems, we're like detectives. We need to understand the story first, THEN figure out the math. Let's learn a process to help us."
"Notice how I had to find something FIRST (total crayons) before I could answer the question. Two-step problems are like that—you need to figure out a piece before you can solve the whole puzzle."
Work through problems that use different combinations of operations:
Distribute worksheets. Remind students to: (1) read the whole problem first, (2) identify what they need to find, (3) break it into steps, (4) check if the answer makes sense.
Sketch the situation. Draw groups, arrays, or a simple diagram to visualize what's happening.
Use counters or students to model the problem physically. Great for "sharing" and "grouping" problems.
Translate the story into numbers and symbols. Use a box or question mark for the unknown.
Start from what you need to find. Ask: "What do I need to know to find this?"
For struggling students: Start with one-step problems only. Provide manipulatives. Use simpler numbers (single digits). Read problems aloud together.
For advanced students: Add a third step. Introduce problems with extraneous information. Ask students to write their own multi-step problems.
For home: Encourage parents to create word problems from real life: shopping (prices, quantities), cooking (recipes, servings), organizing (items, containers).
