Ray's New Primary Arithmetic · Lesson XXIII · Unit 3: Addition
23. Story problems with addition
Goal: Your child solves story problems that add three or more amounts.
You'll need
- A slate, small whiteboard or paper and pencil
What's in the book
Story problems such as "Mary paid 5 cents for ribbon, 4 cents for thread, and 3 cents for tape: how much did she pay for all?" and "Joseph caught 6 fishes, Samuel 3, and Henry 5: how many fishes did they all catch?"
The lesson, step by step
Read slowly
Read the first problem aloud. Ask: What are we finding? What numbers do we need?
Answer in a sentence
Your child answers in a full sentence: "Mary paid 12 cents for all."
Work through the page
Do the rest of the problems the same way.
Act one out
Act one problem out with coins or toys, letting your child be the shopkeeper.
Afterwards
Unit 3 is done. Spend a day reviewing any addition table that is still slow before starting subtraction.
