Every two-digit number is made of tens and ones.
You write down how many tens and how many ones the number has.
Example: The number 23 has 2 tens and 3 ones.
You write the 2 in the T box and the 3 in the O box.
The numbers you write in show the answer.
Example
- 2,3
- 4,7
- 6,5
- 9,2
For parents
What does this exercise practice?
Split a two-digit number into tens and ones.
Common pitfalls
For 40 there are 4 tens and 0 ones. The 0 belongs in the ones box and must not be left out.
How to practice at home
Build numbers with ten-rods and one-cubes, then write down the split.
