🔍 Explanation:
Each number is represented visually using dot arrays (like ten frames), where full frames represent tens and partial frames represent ones. For example:
- A frame with 10 dots = 10
- A frame with 9 dots = 9
The total is calculated by adding the two numbers directly, which matches the visual count of dots.
For instance:
- In
9 + 11, we have 9 dots and 11 dots → 9 + 11 = 20
- In
19 + 19, we have two sets of 19 → 19 + 19 = 38
All answers are straightforward additions of the given numbers.
✔ You can now fill in the blanks on the worksheet with these results.
