Unit 5: Proportions
1. I can represent a ratio in lowest terms in three different ways. (7.C.6, 7.C.7, 7.C.8)
2. I can calculate unit rates using proportions (7.C.5, 7.C.6, 7.C.7, 7.C.8)
3. I can use proportions in real world situations. (7.C.6, 7.C.7, 7.C.8)
4. I can create scale drawings and find the scale factor using proportions. (7.C.6, 7.C.7, 7.C.8)
5. I can calculate the missing sides of similar figures (7.GM.3)
Proportional Relationship - when two ratios are equal, they are said to have a proportional relationship.
Algorithmic approach - using a list of well-defined instructions or a step-bystep procedure to solve a problem.
Fluently – efficient and accurate
Unit Rate - when rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour.
Scale drawings - a drawing that shows a real object with accurate sizes except they have all been reduced or enlarged by a certain amount (called the scale).
Origin - the point on a coordinate plane in which the x and y axes intersect; the ordered pair for the origin is (0, 0).
