Solving+Systems+of+Linear+Equations

Part II (after spring break) Part I (before spring break)


 * Day 1(Wednesday March 2nd and Thursday March 3rd): Identify a system of equations, interpret the meaning of the solution to a system and use the a graph and table to find the solution to a system **


 * Bell Buzzer: In your groups work through the "Systems of Equations" handout. You will need a calculator.
 * Unit Introduction: Systems of Linear Equations
 * Gizmo Exploration
 * //Before exploration group discussion questions//
 * 1) What variable is being graphed on the x-axis?
 * 2) What variable is being graphed on the y-axis?
 * 3) What does each line represent?
 * 4) What is the y-intercept of each graph and what does it mean in the context of this problem?
 * 5) How far is it from where the cat starts to the mouse's hole and how is this represented on the graph?
 * 6) Why are both graphs linear? Can this be true?


 * //After exploration group discussion questions//
 * 1) Describe the instances when the cat was able to catch the mouse. Specifically talk about the affects of changing the slopes or the y-intercepts on whether or not the cat caught the mouse.
 * 2) Describe the instances when the cat was unable to catch the mouse. Why was he unable to do this?
 * 3) How can you tell graphically that the cat caught the mouse?
 * 4) How can you tell in a table that the cat caught the mouse?


 * Solve the System Graphically[[file:Solving Systems using Calculator.pdf]]
 * Homework: Pg. 343 #13, 14, 23, 24, 33 and 39


 * Day 2 (Friday March 4th and Monday March 7th): Solve a system by graphing **
 * Bell Buzzer: Have one person from your group please see me. You will have 5 minutes to prepare your answer to that homework question on paper. Also be prepared to present the answer to the class. All of you, be prepared.
