General Activity Information
 Activity ID: 1899 Title: Ratio and Unit Rates Digital Tool/Resource: Matching Rates Game Web Address – URL: http://www.sheppardsoftware.com/mathgames/ratios/MatchingRates.htm Overview: The activity will reinforce a lesson about unit rates and ratios. This learning activity should be used after a lesson on unit rates and ratios. The activity will ask the student to match the ratio with the unit rate. The winner of the game will be the student with the lowest time.This activity results from the ALEX Resource GAP Project.
Associated Standards and Objectives
Content Standard(s):
 Mathematics MA2015 (2016) Grade: 6 2 ) Understand the concept of a unit rate a/b associated with a ratio a:b with b ≠ 0, and use rate language in the context of a ratio relationship. [6-RP2] Examples: "This recipe has a ratio of 3 cups of flour to 4 cups of sugar, so there is 3/4 cup of flour for each cup of sugar." "We paid \$75 for 15 hamburgers, which is a rate of \$5 per hamburger." (Expectations for unit rates in this grade are limited to non-complex fractions.) NAEP Framework NAEP Statement:: 8NPO3a: Perform computations with rational numbers. NAEP Statement:: 8NPO4a: Use ratios to describe problem situations. NAEP Statement:: 8NPO4b: Use fractions to represent and express ratios and proportions. NAEP Statement:: 8NPO4d: Solve problems involving percentages (including percent increase and decrease, interest rates, tax, discount, tips, or part/whole relationships). Alabama Alternate Achievement Standards AAS Standard: M.AAS.6.2- Recognize rate vocabulary in a real-world situation (e.g., miles per hour, dollars per pound).
Learning Objectives:

The student will be able to use rate language to determine the relationship between a ratio and its unit rate. The student will be able to solve real-world problems with unit rate.

Strategies, Preparations and Variations
 Phase: After/Explain/Elaborate Activity: After teaching a lesson about unit rates and ratios, the teacher will show students how to manipulate the website for the Matching Rates Game. The teacher will use the projector to show the Matching Rates Game activity to the students. The students will work individually matching the unit rate with the correct ratio on the timed version of the game. As the student finishes the game, he/she records his/her time. The lowest time wins the prize! Assessment Strategies: The teacher will monitor the students' work and times. The student should be able to complete the game within three minutes. The students will complete the following exit pass to use rate language to determine the relationship between a ratio and its unit rate.Exit SlipIn a cookie mix, we find molasses cookies, thumbprint cookies, and no-bake cookies in a ratio of 1 : 2 : 2. If a bag of the mix contains 30 no-bake cookies, how many molasses cookies are there?A bag contains 56 marbles, some green and some white. The ratio of green marbles to white ones is 5 : 2. How many white marbles are there? Advanced Preparation: The teacher will need projector and computer with internet access.The teacher will need to be familiar with the website, Matching Rates Game.The students will need their own devices and internet access.The teacher will need to decide what prizes or incentives to use for the winners. Variation Tips (optional): The teacher can place students in pairs. Notes or Recommendations (optional):
