Solve Word Problems Within 100

What students learn

Students learn to read a story, decide whether it asks for addition or subtraction, and represent the situation with an equation. Begin with to see how a real situation can be turned into math.

Why it matters

Word problems are where math meets meaning. Students must understand the language of the story before they can solve it. The comparison language in helps students notice that subtraction can be hidden inside everyday language.

Learn the idea

A good word-problem solver asks, "What is known? What is missing? What operation fits?" shows the move from a story to an equation. Then shows how comparison clues can point to a subtraction equation even when the sentence sounds like a story.

Try it

Read two story problems aloud and ask the student to underline the numbers, circle the clue words, and draw a quick model. If they are unsure, have them explain why the answer should be larger or smaller than the starting amount. Revisit the fence story and the comparison problems until the student can say why the chosen operation fits.

Parent guide

Do not rush to the answer. Ask the child to explain the story in their own words first, then ask which quantity is missing. Use drawings, counters, or a number line if the story feels abstract. The goal is to make the reasoning visible before the computation.
