Lesson Plan
Performance Objectives:
Given the equation of a line in slope-intercept, standard, or point-slope form, students will be able to recognize and/or solve for the slope of the line and recall that parallel lines have equal slopes 4 out of 5 times.
Given a point that lies on the line and the slope of the line, students will be able to substitute the values appropriately into slope-intercept form and solve the resulting equation for the y-intercept 4 out of 5 times.
Given the slope and the y-intercept, students will be able to substitute the values into slope-intercept form of the equation of a line 5 out of 5 times.
Step 1: Pre-Instructional Activities: Check students’ homework and project answers on the board, answer student questions about the homework.
Step 2: Content Presentation: n/a.
Step 3: Learner Participation: Students will be completing problems in assigned small groups. Groups should have 3 or 4 students at varying levels (heterogeneous groups). Each student is responsible for completing all the problems. Remind students that they can use their Desmos Scientific Calculator as a tool to help them! Each student in the group will become the ‘expert’ on two problems, by working out the answer. After all students have become the ‘experts,’ they then will explain their answers and the process to the others in the group.
Step 4: Assessment: Teacher will circulate throughout the groups. Formative assessment through teacher observation.
Step 5: Follow-Through Activities: These types of problems will be included as future “Do-Nows” so learners continue to practice. The skills practiced here will continue to be used when learning how to write equations of lines parallel or perpendicular to a given line throughout the remainder of the unit.
