# Year 1 Autumn Term: Block 2 Addition and Subtraction

For the next five weeks addition and subtraction are the key targets. This begins with adding, using pictures to help count on, the introduction of the add sign and solving missing number problems. Understanding that numbers can be broken into parts (partitioned) is crucial and plenty of partitioning work needs to be done.

Bar modelling is an excellent way to bridge the gap between using concrete objects and the more abstract number sentence and we have included sets for this. The ultimate aim is that children develop sound mental strategies rather than relying on modelling or number lines.

It is also important that children get the chance to look at more open ended tasks of the ‘How many different ways..?’ style of question, where they are encouraged to say how they know that they have found all the possibilities.
