=Chapter Three:Arithmetic Strategies and Area =

In this chapter, you will learn how to:

 * Calculate sums and products efficiently with a variety of strategies.
 * Define and measure area of rectangles and shapes that can be broken into rectangles.
 * Make sense of the standard algorithms for addition, subtraction and multiplication.
 * Use a generic rectangle to multiply, both on paper and mentally.
 * Make reasonable estimates of complicated products mentally.
 * Subtract and multiply positive and negative numbers.

**Think about these questions throughout this chapter:**

 * What strategy can I use ?
 * How can I calculate it?
 * What is another way to show it?
 * How can I measure area?
 * How do area and perimeter change?
