System of Equations Halloween Math Game gives you a good challenge to your math skills as you solve these system of equations problems in order to get to the bonus round. In this bonus round, you must do your best to vaporize as many spooky monsters as you can within the time given. For each correct answer to a math problem, you will enter a 30-second bonus round.

In this game, try to use substitution to solve these system of equations problems. Instead of getting an estimate for the solution by graphing, use substitution as an algebraic model to find the exact solution. For each bonus round, you will have 30 seconds to smash and destroy different monsters by clicking on them. Watch out for a few fast moving monsters, as they are not too easy to catch. The game can be played on computers, smart boards, iPads, and other tablets. You do not need to install an app to play this game on the iPad.

The game **is aligned to these standards:**

**CCSS.8.EE.8.a**

Understand that solutions to a system of two linear equations in two variables correspond to points of intersection of their graphs, because points of intersection satisfy both equations

simultaneously.

**CCSS.8.EE.8.b**

Solve systems of two linear equations in two variables algebraically, and estimate solutions by graphing the equations. Solve simple cases by inspection. For example, 3x + 2y = 5 and 3x + 2y = 6 have no solution because 3x + 2y cannot simultaneously be 5 and 6.
