Reflection: Staircase of Complexity A Friendly Competition - Section 3: Discussion + Closing


I like how the end of this task surfaces the idea of systems of equations without being explicit about them. Students will get to systems of equations and inequalities in the next unit and I think it's important that they develop a conceptual understanding of a system before they are formally introduced. I like how that is done in the context of this task.  I think students can get an intuitive sense first without getting bogged down in the mathematical language of systems.

A Friendly Competition

Unit 2: Multiple Representations: Situations, Tables, Graphs, and Equations
Lesson 10 of 17

Objective: SWBAT interpret key characteristics of graph including rate of change and y-intercept. SWBAT write equations describing graphs. SWBAT begin to conceptualize a system of equations.

Big Idea: Who saves more during the school year? Students graph real world situations, interpret graphs, and write equations to describe graphs.
