HOMEWORK: Finish P28 Prob 3.3 A/B/1a/1b/3
Paper Pool Project Due
Page 38 Problem 4.1 A/B/C

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 erqual 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: Paper pool project Due. Page 38 Problem 4.1 A/B/C. NOTES: HOMEWORK: Make a conjecture (a proposition (as in mathematics) before it has been proved or disproved) about the number of sides of a prism (including the cylinder) and the volume.

HOMEWORK: Make a conjecture about the number of sides of a prism and volume
Page 39 Problem 4.3 A/B/C/2/3 Start

OBJECTIVE: [WASL Testing Day] •To develop streategies 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 4.3 A/B/C/2/3 Start. There can be no box dimensions less than 2cm or more than 10cm. You must have a paper showing all of your labelled calculations. You must make a DECORATED model (net) for the specified juice can AND your designer juice box. This will probably be due the end of class on Friday 4-22 NOTES: HOMEWORK: None

OBJECTIVE: See 4-19 above. ACTIVITIES/ASSESSMENT: Page 39 Problem 4.3 A/B/C/2/3 Assemble. Start on the project to make a largest possible volume cylinder from a single sheet of 8-1/2x11 paper. Be sure to document how you know it is the largest possible. This will be continued next week. NOTES: HOMEWORK:
