This activity is about making two-digit numbers from tens and ones.
Remember that 3 tens is the same as thirty.
3 tens = 30
What about 3 tens and 5 ones?
This is 30 + 5.
So 3 tens and 5 ones make 35.
Examples
5 tens and 2 ones make 52.
2 tens and 5 ones make 25.
7 tens and 0 ones make 70.
Now that we've seen how two-digit numbers are made, let's try some questions on it, shall we?
