Week 5

(Module 1 Topic 2 Lesson 4 - 6: Constant of Proportionality)

Learning objective = Students will use use the constant of proportionality to write and solve equations. Students will determine and interpret the constant of proportionality for quantities that are proportional and represented in words, tables, equations, and graphs.

Living with Diabetes | Calculating Carbohydrates | Grades 3-5, 6-8 Mathematics Teaching and Lesson ResourcesIn this video segment from TV411, a patient discusses how he keeps his diabetes under control. He explains how he keeps track of his carbohydrate intake by carefully reading food labels and keeping a daily journal used to calculate how many carbohydrates he consumes during each meal.

Real-Life Math | Restaurant Manager | Grades 3-5, 6-8 Mathematics Teaching and Lesson ResourcesRestaurant manager Tad Peelen explains how he uses math in his work in this video from KAET. In the accompanying classroom activity, students complete an activity involving one aspect of math that Mr. Peleen mentions: determining quantities of food needed to cater an event, and in the process, converting among measurement units. To get the most from the lesson, students should be comfortable multiplying fractions by whole numbers. They should also be familiar with customary units for weight (oz., lbs.) and capacity (cups, gallons).

A Cage to Save a Whale | Cyberchase | Grades 3-5, 6-8 Mathematics Teaching and Lesson ResourcesIn this video segment from Cyberchase, Matt and Inez have to choose a cage for Spout the Whale. The cages they find in a store come in different sizes and Matt and Inez are not sure of Spout’s exact size. They use estimation and non-standard measurements to estimate Spout's size and select the best cage.

Random Sampling and Estimation: Lake Victoria | Grades 6-8 Mathematics Teaching and Lesson ResourcesLearn how scientists in Kenya are trying to determine the populations of endangered species in the Lake Victoria region. This video focuses on how random sampling and statistics are used during conservation efforts and how the mean can be used to estimate the size of a population, taking math out of the classroom and into real world problem solving.
