Feb 2, 2022 | Roslyn

Math is a subject that is both loved and hated simultaneously. This subject relates to everything we do in our daily lives, making learning and understanding important. However, how can we indulge the young and tender minds in such a complex subject?


Forcing them to solve math problems will not draw their attention or help them. Hence, in this case, “Brain games and teasers for kids” come in handy. Kids have so much fun solving problems and playing games that they will not even realize they are applying math concepts, practicing computation skills, and using logical reasoning.

We have put together some interesting and fun brain teasers for kids with answers that kids of all ages cherish.
