85 brainteasers for kids (and their answers) to battle boredom (2024)

Want to help your kids build critical thinking skills? There's a surprisingly fun way to do it: keep them entertained with a constant supply of brainteasers.

“I am a huge fan of this type of activity for children,” said Laura Linn Knight, author of“Break Free from Reactive Parenting,” who is a mother and a former teacher.
