# Math quiz questions for kids — easy & challenging

Math isn’t boring. Math is fun. You just need to present it to the child correctly. Parents should not completely shift responsibility for their child’s education to the school. If you can get your kids interested in math and other sciences, it will be a huge advantage because it will increase their motivation and academic performance.

Let’s take a look at interesting math problems for children of different ages: from 4 to 11 years old. Then we will analyze some trick tasks for logic and fun tasks. Children would like this.

Do not show this page of the site to children because the answers are visible here. Have the child sit across from you. Just read the assignments and give some time to think. There will be no problems with a long solution. An adult can solve these problems in their head, but a child can use paper and pen if needed.
