MathsBites provides real maths help
for real families

Stage 2, Part B - Year 4

MathsBites is built using the NSW syllabus, giving you peace of mind,
that what you'll get mirrors what your child will say and do in maths in their classroom.

Every concept below will be covered by your child during Stage 2,

and every concept is explained and demonstrated by your MathsBites videos.

Your child will revisit these concepts many times across the year - it’s normal if it takes a while to click.

What this means for you at home:

You don’t need to teach these concepts - just understand what they mean

The videos give you the language and strategies to use with your child, as well as ways to practice the concepts at home.

It’s normal for children to move back and forth between concepts.

You're now proactive rather than reactive.
