We have been learning some really good things about our body recently and we now know lots about our skeleton and muscles. We have also been focusing on how puberty affects and changes our bodies.
I have attached a link to a website which is really useful for the children to explore themselves and also for parents to use alongside your child.
I hope you find this of some use to you.
