I Can…. Identify and calculate unit rates.

Unit Rates Essential Understanding: • A unit rate is a rate that has been reduced to a comparison of 1. Example: • A rate can be reduced by I. Using division- To use this method begin by expressing the rate in the correct order using a fraction bar. (Don’t forget your units). Then you simply divide the top quantity by the bottom quantity. Finally write the quotient as a comparison to 1. II. Using proportional reasoning- This method uses a proportion, in which the first ratio is the given rate and the equivalent ratio is set up to have a denominator of one. To determine the numerator of the equivalent ratio, simply calculate the scale factor of the denominators and use it to scale the given numerator. III. Using cross products/ One step equations. -This method uses your knowledge of cross products to create a one-step equation when you are unable to scale a proportion mentally.

I Can…. Identify and utilize map scales to determine distance.

Map Scales Essential Understandings: • A map scale is defined as the ratio of the distance between two points on the map to the corresponding distance on the ground. • Map scales are typically given in two ways – Verbally: 1 inch = 1 mile – Visually: • A proportion can be used to calculate the actual distance on the ground. Example:

Quick Quiz Please clear your desk of everything except for a pencil and the provided quiz.

I Can…. Utilize map scales

Map Quest • You will work with the people in your row to complete the provided map quest. • You will need a pencil and scratch paper to work each proportion, and a ruler to measure the distances. • You are not to write on, step on, or damge the maps in anyway. • When your time is up, you are expected to fold the map correctly, return all supplies, and turn in the completed quest with all group members names.
