This weekly lesson plan outlines math instruction for 8th grade students on functions over five days. On Monday, students will be introduced to the difference between functions and relations. Tuesday through Thursday focus on representing functions in different ways such as algebraically, graphically, and numerically. Students will use iPads and apps to learn about functions through videos, practice problems, and quizzes. On Friday, students will review the week's content through another quiz and vocabulary activity. The plan incorporates individual, group, and whole-class activities using various technologies to differentiate instruction for different students.
