There are many ways. Start from simple and everyday objects, best to encourage children’s curiosity.

Not sure but you can tell their interest level with logics and numbers

Think it's easier for them to grasp the concept with everyday items

I use everyday scenario, even when we are in the supermarket

There are great online maths games! My kids love Prodigy

Involve it with everyday routine is much better I think

Probably doing the math itself to be honest

We can teach them in every day life

Play little games here and there

Let them pay for their own food
