The 4 page packet is a great way to introduce systems of equations and solving them through gra, Instructions:Included in this set of digital pages are 3 pages introducing systems of equations. The 2nd and 3rd review types of solutions and has students determine how many solutions each given system has. to a system of equations from a graph. As an extension of this activity, I have students work together with their partner to write 2 equations that have no solution, and 2 equations that have infinitely many solutions. Can you identify 3 solutions on this line? This allows students individual think time, and the ability to discuss their thoughts with another student. The table of values are already created for students to fill in as well as guidelines to help students discover the point of intersection. Here is a activity that really delivers! Each worksheet has its own QR code, which is a bar code that links directly to a webpage or online location. Graphic organizers are powerful learning tools that can help a. This activity will help students to understand that the intersection of two lines is a point. It then discusses different ways of solving systems along with the graphical representation of the solution. What does it mean to call a point a solution? * In this lesson, students will: - Learn the definition of a system of equations - Explore what it means for an ordered pair to be, Introduce students to real world systems of equations with this activity.
