Objective / Students will be able to construct a scale model. / The students will be able to find the unit rate using proportions. / Student will be able to write formulas in Excel to calculate the cost and weight of various mammals if they were converted to a metal. / Students will be able to construct a scale model. / The students will be able to find the unit rate using proportions. / Student will be able to write formulas in Excel to calculate the cost and weight of various mammals if they were converted to a metal.

3. CA State Standards  Number Sense  1.2 Interpret and use ratios in different contexts (e.g., batting averages, miles per hour) to show the relative sizes of two quantities, using appropriate notations (a/b, a to b, a:b).  1.3 Use proportions to solve problems (e.g., determine the value of N if 4/7 = N/21, find the length of a side of a polygon similar to a known polygon). Use cross- multiplication as a method for solving such problems, understanding it as the multiplication of both sides of an equation by a multiplicative inverse.  Number Sense  1.2 Interpret and use ratios in different contexts (e.g., batting averages, miles per hour) to show the relative sizes of two quantities, using appropriate notations (a/b, a to b, a:b).  1.3 Use proportions to solve problems (e.g., determine the value of N if 4/7 = N/21, find the length of a side of a polygon similar to a known polygon).

CA State Standards Cont’d  Number Sense  2.3 Solve addition, subtraction, multiplication, and division problems, including those arising in concrete situations, that use positive and negative integers and combinations of these operations.  Algebra and Functions  2.2 Demonstrate an understanding that rate is a measure of one quantity per unit value of another quantity.  Number Sense  2.3 Solve addition, subtraction, multiplication, and division problems, including those arising in concrete situations, that use positive and negative integers and combinations of these operations.  Algebra and Functions  2.2 Demonstrate an understanding that rate is a measure of one quantity per unit value of another quantity.

5. Project Description / Have you ever loved a pet so much that you wanted a statue made of it? Imagine a statue of your pet on the front steps of your home. "Gee, what a wise way to spend hard-earned money," your admiring neighbors would say, or maybe not. In addition to being expensive, these statues would also be heavy. For instance, a 35-lb dog cast in gold would weigh about 670 lb. / You will choose your top 5 favorite mammals to research. From the top 5 mammals you researched, you will choose 1 to build a model, draw a diagram, or create in Google Sketch-up. Your model, diagram, or Google Sketch up must be to scale. You will also find the weight of the different animals and the weight of different metals. Your final project will be an Excel table of the animals with their weights. Visit PHSchool.Com for the links. You will need the following Webcode: avd- 0561 / This project will be completed in class and at home. Any necessary materials for a model or diagram must be provided by the student. It will be due on Friday, March 5,, 2010. Please remember, projects are 20% of your grade. / Have you ever loved a pet so much that you wanted a statue made of it? Imagine a statue of your pet on the front steps of your home.
