E-book, Lesson Plan


Beginning with pictorial representation, this lesson teaches students to write expressions for linear story problems that include a rate of change and an initial value. Students progress from concrete answers ("How much will 4 pizzas cost with delivery?") to abstract ("How much will x pizzas cost?").

Reviewer Comments:

This lesson discusses linear patterns starting from word problems and leading to algebraic equations. In each case, students see the linearity relationship clearly motivated. As the cases become more complex, students see the separate roles of the multiplier and offset., This is a nicely done lesson.
