These are the booklet/worksheets that I use to form the basis for my each of my lessons for the Percentages unit.
Unit: Equations & Inequalities
Lesson 1a: Percentages & The Percent Proportion
Lesson 1b: Quantity = Percent × Whole
Lesson 2a - Percentage Change
Lesson 2b: Finding 100%
Lesson 2c: Percent Review
Lesson 3a: Markup and Markdown Problems
Lesson 3b: Markup and Markdown Problems
Lesson 4: Percent Fluency – What do we know?
Lesson 5: Percent Error
Lesson 6: Consumer Math with Interest
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.
