Technology Resources Needed: 
Desktop computer with interactive whiteboard for teacher and lesson iPad, Chrome book, or MacBook for all students Web 2.0 Scientific Calculator website Web 2.0 is a website that can be saved to Apple or Android devices. If the program cannot be used on the school network, then just use the website. A regular scientific calculator can be used. Khan Academy Website "Missing Angles" interactive lessons: https://www.khanacademy.org/math/ccseventhgrademath/cc7thgeometry/cc7thunknownanglealgebra/v/solvingforunknownangles http://www.commoncoresheets.com/Angles.php for worksheets to copy for all students ("Finding Missing Angles" and "Finding Complementary and Supplementary Angles") 
Background/Preparation: 
Teacher: 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"). Student: 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 multistep equations. 
Before: Bell Ringer: The teacher will have the bell ringer, “Bell Ringer Angles” (see attached document), on the interactive whiteboard for the students to begin working as they come into the classroom. The teacher will have students to write their answers on the interactive whiteboard. The teacher should encourage students to explain their reasons behind their answers. During:
After: While the students are checking their work, hand out the exit slip. The exit slip is in the attachments section called "Exit Angles with Answers". The students will turn in the exit slip as they leave the room. If students finish early, then the assignment is a worksheet called "Early Finishers Angles" in the attachment section. 
Attachments: **Some files will display in a new window. Others will prompt you to download. 
Assessment Strategies 
Informal: The teacher will ask questions to check for understanding of the standard. While visiting the website, Khan Academy, the teacher will select students to come to the Smart board to answer problems. Informal assessments are constantly being made as the lesson is taught. Formal: After the students complete the exit slip, the teacher will check for mastery of the content. 
Acceleration: 
The accelerated students will have a challenging assignment. The problems have multiple variables and steps. The name of the worksheets is Early Finishers (see attached document). 
Intervention: 
The intervention for the students is to allow more time to complete the worksheets. The students can work in groups of 3 or 4 students. The teacher can assign an accelerated student to be the peer tutor for the group. The teacher can also modify the assignment by removing some of the questions.
