Instructions

Play through this interactive game to learn about Understand Systems Of Equations. Suitable for Grade 6, Grade 7, Grade 8.

Main Concepts

A system of equations refers to a number of equations with an equal number of variables.
Understand that solutions to a system of two linear equations in two variables is an intersection of the graph of their two equations.
Solutions for system of equations is an ordered pair and a solution to both equations.
Solutions to Systems of equations that are independent are lines that intersect at one particular point.
Solutions to Systems of equations that are dependent describe the same line, they have all their points in common; hence there are an infinite number of solutions to the system.
Graphs of equations that are Parallel lines will never intersect and so have no solutions.

Discussion Questions

Before the Game

What is a system of linear equations? How are systems of linear equations classified? What are the three types of classifications for systems based on their solutions? What is the point of intersection when you graph two equations on the same coordinate plane? How does the slope of an equation affect its graph? How does the y-intercept of an equation affect its graph?

After the Game

How did you solve the equations so your shot would be at the intersection of the two lines? What does the solution look like when there are an infinite number of solutions? What does a system of equations look like when there is "no solution"? What strategies did you use to figure out which slope to use? What strategies did you use to figure out which y-intercept to use?
