### Big Ideas

Integers:

• are a set of numbers that include the following: (… –3, –2, –1, 0, 1, 2, 3, …)
• include positive and negative whole numbers
• add to number the idea of opposite, so that every number has both size and a positive or negative relationship to other numbers. A negative number is the opposite of the positive number of the same size (Van de Walle and Lovin 2006, p. 131)
• are successive numbers that differ by 1
• form a subset of the rational numbers
• represent the difference between two objects in a set
• are numbers that deal with direction and magnitude.
