2-23-2004 Bring your ruler! Bring your scissors!
1. -Paper Pool Rules .
2. -Pentominos......

OBJECTIVE: [1.2.1]•To develop the concept of surface area by counting the number of unit squares needed to wrap (enclose) a rectangular box •To explore the realtionship between the surface area of a box and the total area of the unit squares needed to wrap the box •To develop the concept of volume of a rectangular box, and strategies for finding it. by filling a box with unit cubes. ACTIVITIES/ASSESSMENT: Warm-Ups: Rates, Standard and Metric measures: IN class - variation of Problem 1 on page 10. Make up a set of pentominos (arrangements of 5 squares) How many of them will form an open box? NOTES: Paper Pool rules check. HOMEWORK: 3 Fraction Problems + P10-11 2-7

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: Warm-Ups: Rates, Standard and Metric measures: Do page 16, Problem 2.1 plus follow-Up. Start on ACE problems page 19 1-7 NOTES: HOMEWORK: 3 Fraction Problems + Paper Pool Report

2-25-2004 Bring your calculator!
1. -PaperPoolReport.

OBJECTIVE: •To select and apply appropriate strategies to make comparisons •To review when ratio and difference strategies are useful in solving problems •To use proportional reasoning to fairly apportion available space so that the group is representative of the larger community ACTIVITIES/ASSESSMENT: Warm-Ups: Rates, Standard and Metric measures: Evaluate the Paper Pool report using the provided scoring guide. If finished, continue with P19 1-7 NOTES: HOMEWORK: 3 Fraction Problems + Finish P19ff 1-7

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: Warm-Ups: Rates, Standard and Metric measures: Start on page 17, Problem 2.2 plus follow-Up NOTES: HOMEWORK: 3 Fraction Problems + P20 #8 and P21 #11

2-27-2004 Bring your ruler! Bring your calculator!
1. =WarmUps Test....
2. =Fractions Test..
3. -Homework: Page 20#8,Page 21#11..

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 in a 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 problmes involving volume and surface area. ACTIVITIES/ASSESSMENT: Warm-Ups Test: Rates, Standard and Metric measures: Fractions Test 14-16: Page 25, Problem 3.1 'Finding the Volumes of Boxes' Do the problme and the follow-up. NOTES: HOMEWORK: P23 1&2
