8.6.3 By the end of eighth grade, students will describe and represent relations, using tables, graphs, and rules.


Use variables to recognize and describe patterns.

    Integers Add and subtract positive and negative integers.   Use red and black checkers. Let the red checkers stand for positive numbers and the black checkers stand for negative numbers. Randomly create problems as +3 - +4 and solve them using the checkers. Create a number line from –20 to 20.
Create problems with positive and negative integers. Show how the solutions can be found by using the number line.
