These are the booklet/worksheets that I use to form the basis for my each of my lessons for the Ratios & Proportions unit.
Unit: Equations & Inequalities
Lesson 1a: Rate & Unit Rate
Lesson 1b: Unit Rate
Lesson 1c: Unit Rate Comparison
Lesson 2a - Part 1: Proportional Relationships
Lesson 2a - Part 2: Proportional Relationships
Lesson 2b: Representing Proportional Relationships
Lesson 2c: Proportional or Non-Proportional
Lesson 3a: Constant of Proportionality (Unit Rate)
Lesson 3b: Representing Proportional Relationships with Equations
Lesson 4a: Ratios of Fractions and Their Unit Rates – Part 1
Lesson 4b: Ratios of Fractions and Their Unit Rates – Part 2
Each lesson is split: firstly, group discovery/investigation - secondly, space for lesson notes - finally, straight forward skill practice. Of course, you can have your students complete this in the order of your choosing.
I, personally, use them as a basis for accelerated groups and students who are able to move independently through a lesson and then adapt them for use with other student groups. Feel free to use and adapt for differentiation towards tiered groups.
