The 3 Magic Steps to Make 10
Strategy Steps
STEP 1
Find the Leader
Spot the bigger number that is already close to 10 (like 9, 8, or 7).
"8 is super close to 10!"
STEP 2
Break the Partner
Ask: "How many more to make 10?" Split the other number to give it what it needs!
8 needs 2. Break 5 into 2 + 3!
STEP 3
Add to Ten
Combine your new 10 with whatever is left over for an easy teen number.
10 + 3 = 13! Done!
Remember: A number bond helps us split numbers into friendly pieces! Letβs see it in action! β

Modeling: 9 + 5
Watch Me Model
Top Ten-Frame: 9 blue dots Needs 1 more!

Break It Down:
9 + 5 = ?
9 needs 1 to become 10.
Split 5 into 1 and 4.
The New Easy Problem:
10 + 4 = 14
So: 9 + 5 = 14!
Look how the 1 completed the top frame into a solid 10! Next: What if we start with 8? β
