1. Record homework in planner. 2. Bellwork: Complete 8th Grade Math Minute 89. Go over correct answers, correct mistakes and record score in Math Minute journal. Lesson (Congruent TrianglesSSS, SAS, ASA) 1. Learn Zillion video: "Identify Congruent Figures" 2. Discuss results of the triangles exploration activity from last week. 3. Remind the class that we did nothing with the angles only the side lengths. The angles "took care of themselves." This is called SSS congruence. All we need are two congruent corresponding sides in 2 triangles, and we know all 3 sides are congruent. 4. Have students draw another triangle using the 3 objects, but this time they should make one side only 8 or 9 inches. Discuss the findings. How do we know if any two of their triangles are congruent? 5. Relate SSS Congruence to the yacht problem. 6. Journal entry: If two triangles are congruent, all of their corresponding parts are congruent. Draw 2 triangles. Color code and list their corresponding parts. 7. Independent practicecomplete SSS Congruence worksheet for homework. Color code corresponding sides. Homework Complete "SSS Congruence" worksheet. Color code corresponding sides. Other Please keep your math binder organized. Refer back to your journal entry if you need help with the homework. There will be a brief quiz over congruent triangle "rules" on Thursday. Files

Bellwork
1. Record homework in planner. 2. Bellwork: Complete 8th Grade Math Minute 92. Papers will be collected and graded. Lesson (Introduction to Scale Factor) 1. Question: What is the difference between congruent and similar? 2. Journal entry: definitions of congruent and similiar 3. Give students each a ruler, protractor, and a worksheet with similar polygons. Ask students to measure and record all of the side lengths in centimeters. 4. Question: How can we prove that these polygons are similar? 5. Learn Zillion video: "Determining Similarity by Comparing Angles" 6. Journal entry: Corresponding sides in similar polygons are proportional. 7. Refer to the "Similar Polygons" worksheet. Color code and list the corresponding sides. 8. Question: How do we prove that our sides are proportional? 9. Refer back to similar polygons worksheet. Create proportions. Check the proportions. 10.
