Addition and Subtraction

We have been using our Base 10 resources this term to help us with addition and subtraction. We call these resources 'concrete' as they are ones we can physically manipulate whilst working out our calculations. We often use concrete resources when we start a new topic to help us understand visually.


Using the Base 10 has enabled us to consolidate and refine our column addition/subtraction methods up to 4 and 5 digit numbers.
