Ok, 15 in your head, let’s fold the two fingers as we count, look at the fingers 14, 13! Yes, where did we stop? 12! YAY

You might think that this game is too easy because it is using numbers up to 10 (children will be trying to snap cards with matching answers, for example 6 + 2 with 4 + 4) but it is perfect if your child needs to speed up mental calculations.
