I am all about brainteasers and puzzles that motivate students to experience math. When we show students that math is more than rules and numbers, we can open a world of problem solving and logic. Here are some of my favorite websites to find those for your classroom or home:
Riddledoo.com offers not only math riddles, but brainteasers too!
Well known author and math expert Greg Tang offers not only engaging and wonderful games you can purchase through his website, but also a subscription to his Tangy Tuesday Puzzle Packs. Below the option to purchase the Tangy Tuesday Puzzles are a few of his FREE puzzles.
Brainfans.com provides a fun and engaging puzzles and pictorial equations at varying levels. Best yet- there are hints and answers at the bottom if needed for support!
