  1. WELCOME TO CAHSEE Week Four

  2. NOTES- any slide with a green title should be written down in your notebook.

  3. Lesson #7- Measurement and Geometry 2.1

  4. Perimeter, Area, Volume(10 mins) • Perimeter- the distance around the object. • Area- the inside of a 2-D shape. • Volume- if you filled a 3-D shape. • Surface Area- the covering of a 3-D shape.

  5. Perimeter 18 feet 10 feet 10 feet 18 feet Perimeter = side + side + side + side = 10.5 ft + 18 ft + 10.5 ft + 18 ft = 57 feet

  6. 8 cm 6 cm 12 cm The area of a Trapezoid 7cm Length of side Area = A= *h 2 h height Length of side h = 6cm, a = 8 cm, b = 12 cm A = (8 cm+ 12 cm) x 6 2 = 20 cmx 6 2 10 x 6 = 60 cm2

  7. Volume of a CylinderA=  3 in 6 in

  8. Area of base = 3.14 x (3x3) x 6= 28.26 in228.26 x 6 = 169.56 in3 3 in 6 in

  9. Surface Area- Rectangular PrismSA= 2lw+ 2lh+ 2wh Length = 5 Width = 3 Height = 4 4 3 5

  10. Bootcamp Practice (15 mins) • Pages 85-86 you may not write on. Copy the questions into your composition notebook and solve.

  11. Bootcamp Practice • Raise your hand if you need any help • Ask questions NOW, the Cahsee will be too late! *Teacher will determine grouping (independent, pairs, etc.)

  14. Lesson #8- Measurement and Geometry 2.2

  15. Composite Figures- 8 mins • Two or more shapes formed together. • In order to solve: • Separate the shapes • Find the area of each • Add/ Subtract them together.

  16. #1 A= l xw A= 8 X 4 A= 32 #2 A= l xw A= 10 X 2 A= 20 Composite Figure 4 yd #1 32 +20= A= 52 8 yd 10yd 6yd #2 2 yd 10yd

  17. Shaded region only #1 A= l xw A= 3 x 3.4 A= 10.2 #2 A= l xw A= 7.3 x 5.8 A= 42.34 #2 #1 42.34 -10.2 = A= 32.14

  18. Bootcamp Practice (10 mins) • Pages 87- 88- you may write on.

  20. Page 88 CHECK YOUR WORK- 3 mins

  21. Bootcamp Practice • Raise your hand if you need any help • Ask questions NOW, the Cahsee will be too late! *Teacher will determine grouping (independent, pairs, etc.)

  22. Turn in all handouts that you couldn’t write on, the ones that you did write on, you may keep those to study.

  23. Exit Slip: (10 mins) • Get your assigned computer/ close notebook • Log-on/ www.achievedata.com/zoom/test • Use the test key from the CAHSEE BOOTCAMP file cabinet under Mrs. Kelley’s page • Exit Slip Name- CB Math Week Four Exit Slip (6 questions)

  24. Time to Switch (1 minute stretch break before we start the next subject)

  25. Reminders: (1 min) • Sign in Laptops • Bootcamp next Saturday • Study over your notes nightly • Room must be left spotless (no trash, chairs on desks, I will check your desk before dismissal)
