Previously Published Data 

1.) Students will determine the height of an unknown object, such as a building or a flagpole. They will use proportion to determine the unknown height. First, students will go outside and determine the ratio of their height to the length of their shadow. Then they will measure the shadow of the unknown object. Using a proportion, the height of the unknown object will be calculated. Next, cross products will be used to find the solution. 

2.) Students will order a series of fractions. They will use a variety of strategies, such as fraction strips, common denominator, reducing to lowest terms, and/ or number lines. 
3.) Students will place the following fractions in order, from least to greatest: 2/5, 1/2, 12/4, 3/9 
4.) Students will work on problems dealing with: Interest Earned: If the bank will pay 5% interest a year on the money you deposit, how much interest will you earn on a deposit of $225.00? Sales Discounts: The sweater you like costs $42. There is a 60%-off sale. How much money will you save? How much will the sweater cost? Tips: Your family has gone out for dinner. The bill for the meal is presented to the table. You want to leave a 10% tip. If the total bill for the meal equals $36.30, how much of a tip will you leave? 
Previously Published Data 

1.) Students will explain, with examples, strategies for comparing and ordering decimals, fractions, and mixed numbers 

2.) Students will find the missing side of a similar polygon by using proportion. 
3.) Students will solve percent problems, such as you are shopping at a sale. The $40 pants are on sale at a 20% discount. Find the amount of the discount and the new price.
