Have students verbalize how to locate the point for each of the other ordered pairs.Students should say to 'start at 0, move 6 units to the right, then 4 units up.' Mark this point on the grid for the class to see. Ask: How would you locate the point for (6,4) on the grid?.Say: Let's locate these ordered pairs on a grid.You can help them by using the rule to write each ordered pair as an equation: 6 – 2 = 4, 7 – 2 = 5, 8 – 2 = 6, 9 – 2 = 7. Students should notice that each ordered pair follows this rule. Ask: Does the same rule apply to the other ordered pairs?.Ask: What rule describes the relationship between the numbers in this ordered pair?Īlthough many rules work for this pair in isolation, elicit from students this rule: the first number minus two equals the second number.Write these ordered pairs where all students can see them: (6,4) (7,5) (8,6) and (9,7).Prerequisite Skills and Concepts: Students should know about ordered pairs and locating points on a grid. Label the x- and y-axes from 0 through 10. Preparation: Draw a large coordinate grid that the entire class can see. Materials: Poster paper or a way to display a coordinate grid publicly for the class straightedge Key Standard: Graph points on the coordinate plane.

A day spent plotting coordinates that fall in a straight line will be a day well spent. Your students may have encountered ordered pairs last year, but it's a good idea to start by reviewing how to locate a point on a grid from an ordered pair.
