When you bundle you always group 10 ones into one ten.
That way you find out the name of the number.
Example: You have 4 tens and 13 ones.
Ten ones become 1 ten. Then 3 ones are left over.
Now there are 5 tens and 3 ones, so 53.
Example
- 53
- 37
- 61
- 49
For parents
What does this exercise practice?
Bundle more than 9 ones into tens and name the number correctly.
Common pitfalls
Children often forget that a new ten is added and only copy the ones. Count the tens again after bundling.
How to practice at home
Use matchsticks to build bundles of ten and single sticks. Bundle together and name the number.
