  2. A Boot-Up 9.9.13 / 6 min. What is the measure of each angle shown? mBAC = ______ mACB = ______ mCBA= ______ 2x x - 16 x B C TTW Intro: We’ve been working w/ s, incl s within s. Today, we’ll continue to work w/ s, but will focus on finding areas of s, as well as other shapes. TSW: Find 2.2.2

  3. 4b. SWBAT: Calculate the perimeter and area of regular and irregular shapes using a variety of methods.

  4. Today’s Vocabulary Perimeter: The total distance around the outside of a 2-dimensional shape. You calculate it by adding together lengths of all the sides of a shape.

  5. PERIMETER

  6. How are Perimeter & Area different?

  7. AREA

  8. What is the area of this basketball court?

  9. Today’s Vocabulary Area: The measure of the space (or region) inside a 2-D shape. It’s measured in square units.

  13. Why would calculating the area of a parallelogram be the same as that of a rectangle? PARALLELOGRAM AREA: A = b x h 10 ft. 50 ft. TSW: Text p.573 #1, 3, 9

  14. The area of the rectangle below is 120 ft.2 How can you figure out what the area of a triangle would be? TRIANGLE AREA: A = b x h ÷ 2 12 ft. 10 ft. TSW: Text p.570 # 5, 9, 2

  15. 2-72-a,b

  16. 2-72-c

  17. 2-73

  18. AREA Warm-up Review your notes from yesterday to find the area formulas for the following polygons. Write down each formula next to its corresponding polygon. Then calculate the areas for each polygon. 10 ft. 8 ft. 18 in. 45 ft. A = ? 50 ft. A = ? A = ? 15 in.

  19. 3mins 3/8/13 DO NOW What is the area of the red shape below? A) 15 u2 B) 18 u2 C) 21 u2 D) 36 ft2 Put your Homework on your desk for teacher to pick-up.

  21. What is the measure of each  shown below? Boot-Up 9.10.13 / 6 min.

  22. 1) You may use a calculator, but you MUST SHOW ALL WORK for full credit. You will not pass the test if all you show is the final answer. 2) You may not speak or make any other type of noise during test. 3) You must keep your eyes on your own papers. 4) If you finish early, raise your hand silently & teacher will give you assignment. Failure to follow these instructions will result in a failure on the test. You have all the skills & knowledge you need to perform well on this test. Just remember what we discussed in class & do your work slowly & carefully. Check your work several times. Good luck!

  40. Mathematical Product: SWBAT:* Learn what qualities make shapes alike & what makes them different. Mathematical Practice / CCSS Standard: SWBAT: 1) Make sense of problems, 2) Persevere; 3) Attend to precision as they describe common shapes & their characteristics. Today’s Objective: *SWBAT= Student Will Be Able To 2 Lessons Today Participation Quiz Today Teamwork important

  41. Resource Manager: Make sure to get all of the supplies & call the teacher over, if needed. Take shape inventory at beginning & end. Make sure all shapes are returned to bucket. Facilitator: Make sure that everyone can participate & that no one dominates the process. Recorder/Reporter: Make sure that everyone can reach & see the Venn diagram & the shapes. Record shape placements / present findings at end of lesson. Task Manager: Make sure each team member justifies statements & decisions.
