Add three numbers – make ten
Key notes :
Understanding Making Ten:
- Explain that making ten means combining numbers to reach a total of ten.
- Use visual aids like ten frames or counting blocks to illustrate the concept.
Combinations of Numbers:
- Introduce different combinations of numbers that add up to ten. For example:
- 1 + 2 + 7 = 10
- 3 + 4 + 3 = 10
- 5 + 5 + 0 = 10
- List all possible combinations for students to see and practice.
Using Addition Strategies:
- Teach students to look for pairs that make ten, such as:
- If they know 8 + 2 = 10, they can think of adding 8 + 2 + 0.
- Encourage them to break down numbers into parts that help make ten.
Learn with an example
🖋️ Add: 5 + 5 + 1 =
Hint: Start by adding two of the numbers to make a 10.
First, add 5 and 5 to make a 10:
5 + 5 + 1 = ?
10 + 1 = ?
Now add 10 and 1:
10 + 1 = 11
The sum is 11.
