What do students understand? What gaps do they have in their understanding? What's greater, 2 to the third power or 3 to the second power? Students take a quiz and then work to understand that repeated multiplication is represented with exponents.
What do students already know about number characteristics and the order of operations? What gaps do students have in their understanding? Students take the Unit 1 pretest in order to inform instruction.
Why do we need an Order of Operations? What is 5 + 3 x 4? What is 3 x 4 + 5? Students work through examples to get at these questions and work with the order of operations to simplify numerical expressions.
