What is an easy way of teaching maths to primary school kids?
You've to connect with them physically mentally and emotionally too. For that you need to teach in such way that even they enjoy and find learning math as fun. Everyday objects also help you teach your child that objects don't have to be identical to be important in math. Counting apples is a great math lesson, but counting apples, oranges, and watermelons together expands the thought process. The child is connecting counting with various objects, instead of running through a routine numbers game of 1, 2, 3.
Try to connect as much as you can and try to keep that session as something funny and enjoyable, that everyone enjoys.
Best wishes. Thank you.
