The first step is to print the angles on cardstock, laminate and then cut into two angles. L and G are labeled on both sides so that when the angles are cut apart both will be labeled. I give each set of students a set of the angles and a couple of dry erase markers. I like to work this activity in groups of three. When working with three students…students 1 and 2 get a smaller angle and student 3 will represent the two angles added together. Students 1 and 2 should first label their angles and then place the two angles together for student 3. Next have the students write the equation representing what they have and then solve.
I work #1-3 with the students as examples. My email is firstname.lastname@example.org if you have any questions.
