Mastery is the idea of applying mathematical skills in a flexible and adaptive way. We sometimes call this being "agile" with Maths.
From feedback, we are hearing that some children are flying through calculations. This is obviously great as they are showing sound skills but they need an additional challenge.
If your child is storming their worksheets, consider giving them these tasks instead.
They will rely upon their calculation skills but this should push them a little further.
In school, when children approach this mastery work, we tend to allow a little bit of struggle before offering support. Such support is often through questioning rather than demonstration.
We would be happy to talk bout how to use these resources further if you contact us via email to arrange a suitable time.
