Welcome to a new NYA blog for students in Math 7. Here we will be discussing how we think WITH math strategically.  Each week I will post a new Puzzle of the Week. Do NOT post your answer to the puzzle. Instead, explain your thinking strategy or write a helpful hint to allow others to solve the puzzle. If you find and interesting puzzle that you think would make a great Puzzle of the week, please send it in!
