Tens and ones
Tens and ones helps children practise splitting any two-digit number into its tens and ones, and building numbers back from their parts. Read the short guide and look through the examples before choosing online practice or a printable worksheet.
How to solve this
- Every two-digit number is made of tens and ones: in 47, the 4 stands for 4 tens (40) and the 7 for 7 ones.
- Identify the tens digit first, multiply it by 10, then add the ones digit to get the full value.
- Check by reading aloud: "four tens and seven ones" — does the written number match?
Examples
47 = ?
4 tens + 7 ones
6 tens + 3 ones = ?
63
80 + 5 = ?
85
