Two-digit numbers can be partitioned into tens and ones.
The order of the digits tells us their value.
We can use a Gattegno chart or a place value chart to help us remember what the digits on a two-digit number represent.

Children may not understand the importance of the order of the tens and ones digits in indicating the value of each part of a two-digit number.

Use place value charts, place value arrows and Gattegno charts to reinforce the value of each digit.
