3x+4=9 5x-6=12 3/5=2/3x÷3/4 3.74x/2=162. Page 16, Problem 2.1 A & B (table)
OBJECTIVE: •[1.2.1]To develop strategies for finding the surface area of a rectangular box •To determine which rectangular prism has the least(greatest) surface area for a fixed volume •{1.2.2}{1.2.3]To reason about problems involving surface area ACTIVITIES/ASSESSMENT: Page 16, Problem 2.1 A & B (table) Investigate the possible number of whole cube rectangular arrangements. Use a table for the data. If time permits, migrate to problem 2.2 on page 17. Create the data necessary to investigate 8, 12, 18, 27, 30 32, and 64 cube arrangements into rectangular packages. Use this data to make a general conjecture about the rectangular arrangement of cubes that requires the least amount of packaging materials. NOTES: HOMEWORK: Page 22 #13 a/b/c

Pick's Theorem simply has us count up the number of points on the boundary of the polygon (where the rubber band touches a nail head) and divide this number in half. Then add the number of points in the interior of the polygon (inside and not touching the rubber band) and subtract 1.
Area = Boundary points/2 + interior points -1

3. Pick's Theorem
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: Introduce Picks on 10x10 geoboard paper - then continue to Introduce and use Pick's Theorem to calculate the area of students hand (on CM paper) NOTES: Area = Boundary points/2 + interior points -1 HOMEWORK: Finish Hand Calculation
