This file includes a flipchart, PowerPoint presentation, multiple formats of notes (color, grayscale, and skeletal), two worksheets to use as practice after the lesson or for homework, and the answer key for the worksheets. The flipchart has 12 pages that explain an introduction to ratios and equal ratios. There are examples and interactive Activboard elements on the flipchart. The PowerPoint does not have those interactive elements. The color and grayscale notes contain 4 flipchart pages per 8.5x11 for a total of 3 pages of notes. The skeletal notes are 3 pages also and follow along with the flipchart. The worksheet is a 2 page document that contains practice problems for the skills taught in the flipchart as well as problem solving word problems. If you would like to see a sample, you can download the worksheet and grayscale notes for FREE in my store. If you have any questions, please email me!
