![]() Label the first column x, the second column x + 5, and the third column y. Draw a table with four columns and five rows.Students should say that the equation means "a number plus five equals another number," or a comparable statement. Ask: How could you say this equation in words?.Write the equation x + 5 = y publicly for the class to see.They should also be able to recognize and interpret an equation. ![]() Prerequisite Skills and Concepts: Students should know about ordered pairs and locating points on a grid. Ensure all students have a copy of the grid. Label the x- and y-axes from 0 through 10. Preparation: Draw a coordinate grid where all students can see it. Materials: Poster paper or a way to display a coordinate grid publicly for the class straightedge one copy of a coordinate grid, a straightedge, and lined paper for each student Key Standard: Interpret an equation as a linear function, whose graph is a straight line. One example could read, " Rule: The first number plus three equals the second number ordered pairs: (2,5) (3,6) (4,7) and (5,8)."ĭeveloping the Concept Finding and Graphing Points for Linear RelationshipsĪt this level, students will begin to see the relationship between equations and straight-line graphs on a coordinate grid. Have students identify the rule and explain how to graph the points.
