Week 18

(Unit Rate - cont'd)

Learning objective = Students use their understanding of ratios to solve problems using rate, defined as a special type of ratio. They write two unit rates for the same situation and consider which one is most useful based on the question. Students solve problems by determining the better buy, comparing rates in real-world situations, and using rates to make predictions.

Parents can support learning at home by helping students connect this week’s lesson to real-life examples and practice explaining their thinking. Encourage your child to explain each step aloud rather than simply memorize a rule = SAMPLE TEST QUESTIONS + MORE QUESTIONS

***If your child needs more challenge, they can move at a faster pace by using this site to study the concepts of future lessons. Mr. Pierre will strive to prepare lessons two weeks ahead of the current week. Also, Khan Academy is a great enrichment resource***

Lesson 3Seeing Things Differently Multiple Representations of Unit Rates 1 TOPIC 3 Unit Rates and Conversions Many Ways to Measure What Is the Best Buy? Seeing Things Differently 1 2 3

I <3 Math: Percent as a Rate | Grades 3-5, 6-8 The Ratio Concept and Ratio Language (Grade 6) Teaching and Lesson ResourcesA presentation of multistep ratio and percent problems to illustrate the concept of percent as a rate. This I <3 Math episode uses real-world comparisons to convert rates into equivalent percentages.

Statistical Variability: Time (to) Travel | Grades 6-8 The Ratio Concept and Ratio Language (Grade 6) Teaching and Lesson ResourcesDiscover travel times for trips you may not have even realized were happening all around you, every day. This video focuses on unit rates, specifically the speed of light and speed of sound and providing an opportunity for students to discuss other unit rates. This video was submitted through the Innovation Math Challenge, a contest open to professional and nonprofessional producers.

Estimating Time from Rate | Cyberchase | Grades 3-5 Solving Problems With the Four Operations Teaching and Lesson ResourcesIn this video segment from Cyberchase, Harry is in line to buy a ticket to a Broadway show, but the line is moving very slowly. He is not sure if the line is moving fast enough for him to get to the front and buy his ticket before the ticket window closes. Finally, Harry makes an estimate to decide whether he should stay in line or go see a movie instead.

Scale City | Proportional Relationships in the Real World | Grades 6-8 Unit Rates and Rate Language (Grade 6) Teaching and Lesson ResourcesIn this video, students visit the Kentucky Horse Park where they are introduced to the question How are speed, time, and distance interrelated? The accompanying activity builds on a demonstration from the video of the length of Man o’ War’s stride versus the length of a person’s stride by allowing students to measure their own strides versus that of the great racehorse.
