Lily is the oldest, then Max and then Zoe. If Max is older than Zoe, Zoe must be the youngest of the three.

Answer: Down
Up and down point in opposite directions, just like hot and cold are opposite temperatures. Opposites help children learn new words.

Kids IQ Test – Fun Brain Games for Children

Children love puzzles, and brain games are a great way to practice thinking skills while having fun. This kids IQ test uses simple questions about numbers, letters, shapes, words and order. Each answer comes with a short explanation, so children can learn how to solve the puzzle, not just whether they were right.

The first intelligence tests were made for children. In 1905, the French psychologist Alfred Binet and his colleague Théodore Simon created a test to find pupils who needed extra help at school. Their questions asked children to name objects, repeat numbers and compare things. Modern children's tests are still given only by trained psychologists.

This quiz is not one of those official tests and does not give an IQ score. Instead, it is like a playful warm-up. Questions about patterns help with math, odd one out puzzles train sorting and grouping, and word pairs build vocabulary. Questions about who is older or what day comes next teach children to keep several facts in mind at once.

Parents and teachers can make puzzles more fun by solving them together and talking about the answers. Asking a child to explain why an answer is right is a powerful way to build reasoning. Children can also create their own patterns and odd one out puzzles for friends and family.

Brain clubs such as Mensa run puzzle activities for young people, and many schools use logic games in class.

Please note: this quiz is made for fun and brain practice. It is not a standardized intelligence test and it does not measure or give an IQ score.
