It’s a lot, right?
Don’t worry … MathsBites walks you through every single one, so that you are:
clear on exactly what your child is learning and how to help using the language and strategies they’ll use in class
ready to help them work with the maths concepts that are a part of their everyday lives
prepared, so when they get ‘stuck’, you can help them through
proactive rather than reactive.
