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.
You'll be clear on exactly what your child is learning and how to help
You're now proactive rather than reactive.
