Fun and Challenging Math Problems for the Young, and Young At Heart These problems are aimed at junior high and high school students with a flare for mathematics and logic.

These are "real world" problems, rather than abstract riddles about sets or trigonometry etc. The questions should be accessible to a wide audience, even if the answers are not. When you find a question that interests you, it's tempting to just read the answer at the end of this web page, but please don't - that would spoil the fun.

Instead, think about the problem in your spare time for a few days. Talk about it with your friends. Then, if you're really not getting anywhere, or you think you've got the answer, come back and read the answer. Educators might want to present the problem on Friday, let the students think about it over the weekend, and talk about it on Challenging math problems.

This is a high traffic, well focused web page; see how you can advertise with us. A school has 1, students and 1, lockers, all in a row. They all start out closed. The first student walks down the line and opens each one.

The second student closes the even numbered lockers. The third student approaches every third locker and changes its state. If it was open he closes it; if it was closed he opens it.

The fourth student does the same to every fourth locker, and so on through 1, students. To illustrate, the tenth locker is opened by the first student, closed by the second, reopened by the fifth, and then closed by the tenth. All the other students pass by the tenth locker, so it winds up being closed.

How many lockers are open? A checkerboard is missing two of its squares. The lower left square and the upper right square are gone. That leaves 62 squares on the board. You are given 31 dominoes. Each domino is a rectangle that can cover exactly two squares on the checkerboard.

Can you place all 31 dominoes on the checkerboard so that all 62 squares are covered?

There are six people at a party. Prove that there are three people in this party who know each other, or three people who are complete strangers to each other. There are two correct answers. There are many variations floating around. This configuration has only one answer. You're on a high bridge one mile long.

If your life depends on it, you can sprint at 10 miles per hour mph. Indeed your life depends on it, because you look behind you and see a train coming. If you run back to the beginning of the bridge you'll jump out of the way just in time - just as the train reaches the bridge.

If you keep going across the bridge you'll reach the end of the bridge just in time, just as the train reaches the end of the bridge. How fast is the train going? There are 3 cannibals and 3 missionaries on one side of a river.IXL is the world's most popular subscription-based learning site for KStandards-based Learning · K Math & English · Adaptive & IndividualizedCourses: Math, English, Science, Social Studies, Spanish.
