The teacher will need to preview the video to determine good places to stop and ask questions and allow the students to ask questions. The teacher will need to adjust the vocabulary of the student to the vocabulary of college and career ready standards. Students in different locations may use different vocabulary words for the types of angles. The angles are listed in the bell ringer attachment. The teacher can develop a word wall with the names of the different angles such as complementary angles, supplementary angles, vertical angles, adjacent angles, exterior angles, and remote interior angles. The teacher will need to visit the website http://www.commoncoresheets.com/Angles.php for worksheets for the students ("Finding Missing Angles" and "Finding Complementary and Supplementary Angles").
The student will need to understand the meaning of the following terms: complementary angles, supplementary angles, parallel lines with a transversal, and vertical angles. The student will need to have experience in writing multi-step equations.
