In Year 3 we are learning how to add and subtract 3 digit numbers using the column method.

We have been using manipulatives to help us combine numbers to add and then take away amounts using subtraction. We all had our own HTO place value grid and have been using counters to represent hundred, tens and ones,

We then carries out some pictorial calculations then abstract – we have been making sure that all of our ones are in the same column, all our tens are in the same column and then all our hundreds are in the same column.

We are becoming fluent at this and are now using our knowledge to solve problems.
