Number Facts and Times Tables

At Harris Primary Chobham, we prioritise students mastering the number facts and times tables relevant to their year level. This is crucial because having quick recall of these key number facts helps lighten the cognitive load and frees up working memory. Unfortunately, our 'working memory' is very limited and it is all too easy to overload it! If number facts are securely learnt and stored in our 'long-term memory', then we can simply draw upon them when we need them ... and not use up our limited working memory by having to calculate facts. A freed up working memory allows us to focus on the real maths - usually a problem - at hand! Overlearning can only happen with dedicated practice, which requires opportunity and motivation.

At Chobham, we plan maths using NCETM. Our whole curriculum can be accessed by clicking this link which will take you to their website. The website also has plenty of resources to support your child with their learning at home for example, here.
