This week's PoW is another student submitted problem. In it, Sam is trying to figure out what 0.9 repeating could be since he can find fractions to represent all other repeating decimals like 0.1 repeating. He thinks it might be the same thing as 1. Do you? Use mathematical reasoning to support your answer. Good luck!

This week's Problem of the Week is a student submitted problem from a recent PoW Hand-in. In it, you are challenged to determine which thief is guilty based on truths and lies told by five suspects. Give it a try and good luck!
Welcome back from Spring Break everyone! Time is flying by and the next few months will be gone before we know it. This week's PoW is an interesting one that was not as easy as I thought when I came across it. You must place 4 coins at the vertices of a square and then create a smaller square by only moving two of the coins. Many questions have been asked, but here's what counts as a square: all four sides must be the same length and all four corners must be right angles. So no, a rectangle will not solve this one. Sorry! Give it a try and good luck!!

What are PoWs?Problems of the Week are puzzles, problems and questions I give out in a 4 week cycle. The first three weeks are new problems for students to try. The fourth week is a chance for reflection and an opportunity for students to choose one of the three PoWs to hand in as a showcase of their problem solving abilities. Hand-in OutlineArchives
