Major Objectives of Chapter 5: Understanding Integer Operations

Students will be able to:

o use real-world situations to illustrate/model the meaning of an integer;

o use equations to demonstrate the mathematical need for integers;

o use models and mathematical reasoning to explain integer operations;

o identify the properties of integer addition and multiplication;

o compare two integers and order a set of integers;

o choose an addition or multiplication equation and verify it using the basic properties;

o state the absolute value of a number;

o state the opposite (additive inverse) or a given number;

o illustrate and explain addition and subtraction of integers using the two-colored chip model, the pattern model, the charged-particle model, and/or the number line model; and

o given two integers, determine which is greater and explain and/or illustrate why.
