- The child learned that numbers can be written using a place value system.
- They learned that the ones column represents single digit numbers (0-9).
- They learned that the tens column represents numbers in multiples of 10 (0, 10, 20, etc.).

- Practice different addition and subtraction problems within the tens column.
- Use real-life situations to reinforce the concept of ones and tens, such as counting groups of objects by tens and ones.
