Complete the addition sentence – make ten
Key notes:-
ππ‘ What is βMake Tenβ?
βMake Tenβ means finding two numbers that add up to 10.
Example:
β‘οΈ 6 + 4 = 10
π§ π’ Use the Missing Number
In an addition sentence like
β‘οΈ 7 + ___ = 10
we find the number that joins 7 to make 10.
Answer: 3
ππ¦ Use Counting On
Start from the first number and count up to 10.
Example:
β‘οΈ 8 + ___ = 10
Count: 8β¦ 9, 10 β 2
π¨π Ten Frame Helps
A ten frame shows how many more boxes we need to fill to reach 10.
If 5 boxes are filled,
empty boxes = 5,
so β‘οΈ 5 + 5 = 10.
π―πββοΈ Make Ten Facts
These pairs always make 10:
- 1 + 9
- 2 + 8
- 3 + 7
- 4 + 6
- 5 + 5
Students can memorize these β
πβοΈ Fill the Missing Number
Examples:
- 4 + ___ = 10 β 6
- 9 + ___ = 10 β 1
- ___ + 7 = 10 β 3
ππ Making Ten Makes Addition Easier
If kids learn make-ten combinations, bigger additions become easier later!
