Once students understand the order of operations, they often just get stuck doing increasingly difficult practice problems. That's a sure-fire way to squelch learning, though. Here, students determine where to place parentheses to make the greatest change in an expression.
Students uncover patterns with exponents and then make predictions about the powers of 0 and 1.
