Division Word ProblemsDraw a diagram, then write a math sentence
Let's think about division word problems by drawing a tape diagram. If you find "the total" and "the number in one group," you can write the math sentence.
The narration and the pictures are in Japanese. You can hear the same words that are used in class at a Japanese school.

- Use a tape diagram to check which of the total, the number in one group, and the number of groups is known and which one you are finding. Please try not to decide the math sentence from words like "each" alone.
- Finding the answer by using the times tables backward, and checking it with multiplication, helps your child see how multiplication and division are connected.
