Lesson Plan 1: Left Hand, Right Hand - Solving Systems of Equations
In this lesson, students compare the speed at which they write with their left hand to the speed at which they write with their right hand. The experiment serves as a vehicle to help students develop a conceptual understanding of the three different types of possible solutions to a system of two equations with two unknowns. This lesson plan is based on the activity Jenny Novak uses in the video for Part I of this workshop.
Two 50-minute periods
Systems of equations
Students will be able to:
Create scatterplots for two sets of data and find the equation of a line of best fit for both sets of data.
Determine the three different types of possible solutions to a system of two equations with two unknowns.
Interpret the meaning of the intersection of two lines as a solution to a system of equations.
