I made this file to help introduce students to ratios. It's a 6 slide PowerPoint presentation that walks students through what a ratio is, when you use them, and how to write them. This is a great supplement to your ratios teaching. Be sure to view it as a show. By the way, I have another one of these files for proportions.

Maps are a great way to examine proportions because they are drawn to scale using proportions. In this activity, students use the classroom map and a ruler to figure out the actual size of states and actual distances between locations in the United States. Students use the map scale (i.e., 1 inch = 30 miles) to set up a proportion with the measurements they get. This is a fun way to get students up and moving and practicing proportions in a real-world context.

I've bundled together my 3 ratios and proportions activity. Included in this download are 2 slideshows that can be used to introduce students to ratios and proportions. These shows will assist you in a classroom discussion/lecture on the topics, and they are a great resource for students to take notes from. The last file in this download is an activity requiring students to use the classroom map and its scale (i.e., 1 inch = 500 miles) to figure out the actual sizes and distances of objects o

This PowerPoint can be used to introduce students to graphing linear equations. It should be played as a slideshow, where it steps students through linear equations by starting with the basic idea of graphing a function. The presentation ramps up to focusing on real-life situations that might be represented by a function. The show ends by looking at different graphs and asking students to think of a real-world situation that might match the given graph.

I made this file to help introduce students to proportions. It's a 4 slide PowerPoint presentation that walks students through what a proportion is, when you use them, and how to solve them. This is a great supplement to your proportions teaching. Be sure to view it as a show.
