# Year 2 Autumn Term Block 2: Addition and Subtraction

For the next five weeks addition and subtraction takes centre stage. Starting with numbers up to a total of 20, children will be expected to understand the relationship between addition and subtraction and identify related facts.

Mental skills are vital when adding a single digit to a 2-digit number and subtracting a single digit from a 2-digit number. This will continue when working with 2-digit numbers as children gain a range of strategies to work out answers.

Children will also be introduced to the column method of addition, leading to an exchange when there are more than ten ones. In a similar way subtraction using columns will be introduced where children use their knowledge that one ten is the same as ten ones.

A great deal of progress is expected here, especially in a relatively short time in the first term of the school year. Addition and subtraction are not considered as a block again during the year but it is essential to provide plenty of opportunities to use both in other areas, such as measurement and problem solving.
