Three students will come up to the board to display their responses for the class. Next a student will read the objective, "SWBAT solve real world scenarios using systems of inequalities".
Using Guided Notes, students will solve linear systems of inequalities. By this point in the year students will have solved many Algebraic word problems. Today's task should feel familiar.
Example One: I will ask the class to read the prompt first, and then underline the information that we will need to construct 2 inequalities. Once we have created our system, I will ask students to graph it on their paper.
The best part of this lesson lies in the analysis of each solution set. Once the system has been graphed, I will probe students understanding by asking them to fully answer each prompt:
Students will work with a partner in 10 minute time-chunks to complete the remaining examples. We will review responses as a whole group at the end of each chunk, with heavy emphasis on analyzing possible solutions, and using the graph to choose the best answer.
