In the place value chart you show each number in tens (Z) and ones (E).
Example: 47 has 4 tens and 7 ones.
So the chart shows Z=4 and E=7.
You can also work the other way round, build the number from Z and E!
The numbers already filled in show the solution.
Example
- 4,7
- 38
For parents
What does this exercise practice?
The place value chart makes bundling into tens and ones visible.
Common pitfalls
The order matters, tens on the left, ones on the right. Swapping them changes the number.
How to practice at home
Bundle with sticks, 10 sticks make one tens bundle.
