💡 Key Ideas (Quick Guide)
✏️ Word Problems are stories that represent multiplication or division questions.
✏️ Step 1: Identify groups and items per group.
✏️ Step 2: Decide if multiplication or division is needed.
✏️ Step 3: Draw arrays, diagrams, or Think Boards for visual understanding.
✏️ Step 4: Write the number sentence and solve.
✏️ Creating your own word problems reinforces understanding and connects math to real life.
- ✏️ Example:
- “7 children each have 3 marbles. How many marbles in total?”
- Array: 7 rows of 3 dots
- Diagram: 7 children → 3 marbles each
- Number sentence: 7 × 3 = 21
