Math is a difficult subject. Sometimes you’re “fighting” with one task and it seems like you’ve already tried everything but it still can’t be solved! When I was at school, my teachers used to tell me  that sometimes the solution lies on the surface, you need just a little distraction. How about this DIY calculator? It starts off as a blank sheet of lined paper that your kid can customize however he or she likes. Your child still has to draw the right numbers in the correct locations but apart from that he or she can let imagination go wild! Your kid will start thinking outside the box and the solution will come by itself. Good luck!
