1. Pp103-105 Unit Test
2. Warm-Ups:Fraction/Decimal Division

OBJECTIVE: 1.3.1 Understand the concept of similarity. 1.1.4 Understand the concept of direct Proportion. ACTIVITIES/ASSESSMENT: Finish Pp103-105 Unit Test if not already done so. Expnad on the concept of probability to include pricing and similar shapes other than triangles. Start a review of area and perimeter and include volumes of rectangular prisms. NOTES: •determine circumference, perimeter, and/or area of a circle, rectangle, and/or triangle. •determine volume and/or surface area of a rectangular prism. •determine linear dimensions of a circle, triangle, or rectangle based on a given circumference, perimeter, or area. •determine linear dimensions of a rectangular prism based on a given volume or surface area. From Measurement. HOMEWORK: Define exponent

C=πd
P_n=s₁+s₂+...+s_n
A = πr²
A = lw
A=½(bh)
x² = units of area measures
v=lwh
Surface Area = 6 surfaces on rectangular prism
(prism - parallel bases)
x³ = volume

1. HOMEWORK Due today: Define exponent
2. Warm-Ups:Fraction/Decimal Division
3. Review Perimeter, Area and Volume

OBJECTIVE: 1.2.1 Analyze how a change in a linear dimension affects other linear measurements (perimeter, circumference) and area measurements. 1.2.5 Apply formulas to find measurements of circles, triangles, and rectangular prisms. ACTIVITIES/ASSESSMENT: Review of area and perimeter and include volumes of rectangular prisms; Review the use of exponents in calculations. Set up problems where changes in a dimension is reflected in the results. NOTES: See ME01 HOMEWORK: Draw (not sketch) a triangle and square w/ same perimeter.

2. Warm-Ups:Fraction/Decimal Division

OBJECTIVE: 1.2.1 Analyze how a change in a linear dimension affects other linear measurements (perimeter, circumference) and area measurements. 1.2.5 Apply formulas to find measurements of circles, triangles, and rectangular prisms. ACTIVITIES/ASSESSMENT: Using exponents, set up the measuremetns for the George Morph family. Linear, surface and volume. Give considerations to systems and units. NOTES: HOMEWORK: Triangle and Square of the same area >10 un²

AVERAGE VOLUME: Find your weight in pounds. Divide by 62.42 pounds per cubic foot. -or- Find your weight in Kilograms. Change to grams. Divide by .9225 grams per cubic centimeter (ml).

"The surface area may be calculated by multiplying 0.007184 times the weight in kilograms raised to the 0.425 power and the height in centimeters raised to the 0.725 power." [Assume a height of 5'8" (170 cm) and a mass of 150 lb (68 kg).]
