Part 1: Lesson Description
Recipes & Ratios: Mobile Learning Exercise
Abstract
Proportional relationships are everywhere. They are used to compare professional athletes and to help shoppers get the “best bang for their buck” at the grocery store. They help us build models and designs and are used in many business applications. This lesson plan introduces proportional relationships, ratios and unit rates at the grade 6/7 (C) level and requires adult learners to identify and compare ratios using the Padlet application.
Targeted Skills
Key skills covered in this lesson include:
- Identifying and comparing ratios
- Problem-solving using proportional relationships
Learning Objectives
By the end of this lesson, the learner should be able to:
- Identify ratios and briefly describe the concept of a ratio using an example, e.g., a ratio of 3:4 means that for every 3 of one thing, there is 4 of another (CCR, 6.RP.1)
- Identify unit rates a/b can be associated with a ratio a:b with b ≠ 0 (CCR, 6.RP.2)
- Use proportional relationships to solve simple real-world problems (CCR, 6.RP.3).

2. Presentation / Modeling / Demonstration
Instructor sends email to students.
Time: 6 minutes
'Here is a link to a presentation that teaches you to identify and compare ratios. Take a few minutes to review the information before we complete our exercise. If you need an app to open the file, the Prezi app is available for free from the App store (www.apple.com/appstore). Adobe Flash Player will also open the presentation.'
3. Practice
Instructor sends an email to students.
Time: 8 minutes
'Now that you have more experience in identifying and comparing ratios, go to the Padlet site and follow the instructions on the screen. Your answers will be reviewed by the instructor and you will receive private feedback via email.'
