Thinkuknow have created some more activity packs that you may find useful. There are now three packs for the age groups: 4-5 yrs, 5-7 yrs and 8-10 yrs plus ones for secondary if you have older children too. They are intended to provide you with support and resources to help you learn about online safety at home with your child.
