Page 24, Problem 3.1 A/B/1/2/3 start
OBJECTIVE: •To develop a strategy for finding the volume of a rectangular prism by filling it with unit cubes. and to recognize that the number of cubes in the bottom layer is equal to the area of the base •To determine that the total number of unit cubes ina rectangular prism is equal to the area of the base times the height (the volume), and to discover that this strategy works for any prism •To learn that the surface area of a prism is the sum of the areas of its faces, and to apply this strategy to any right prism •To reason about problems involving volume and surface area ACTIVITIES/ASSESSMENT: Page 24, Problem 3.1 A/B/1/2/3 start today. Finding Volumes of rectangular prisms. NOTES: HOMEWORK: Page 29 1-3

OBJECTIVE: See 5-10 above. ACTIVITIES/ASSESSMENT: Finish Page 24, Problem 3.1 A/B/1/2/3; Start page 26, Problem 3.3 A/1/3 start. Discuss/review finding the area of irregular figures - find the meanof the inner and outer measures. Inner measure = the number of whole squares in the area. Outer measure means the number of squares INSIDE OF and touching the figure anywhere. NOTES: HOMEWORK: Page 32 #11

OBJECTIVE: •To develop strategies for finding the volume and surface area of a cylinder •To compare the process of finding the volumes and surface areas of cylinders and rectangular prisms •To investigate interesting problesm involving the volumes and surface areas of cylinders and prisms. ACTIVITIES/ASSESSMENT: Page 39 Problem 4.2 - making a cylinder from a net. NOTES: Labsheet/scissors. Will need a session on comparing the volumes of the rectangular prism with the formulas for the cylinder as an intro to lesson 4.3. HOMEWORK: Page 41 #1

Page 40 Problem 4.3 + Follow Up 2&3
OBJECTIVE: See 5-12 above. ACTIVITIES/ASSESSMENT: Page 40 Problem 4.3 + Follow Up 2&3. In this lesson students will create a package for a juice box to replace a juice can. They will make a flat pattern and assemble both items. they will need to keep a neat record of their calculations. NO DIMENSION MAY BE LESS THAN 2cm NOR MORE THAN 10cm! NOTES: Volume of a cylinder = PI x r² x h HOMEWORK: Page 64 #14
