SMARTBOARD lesson on ratios, fractions, percentages, and more

This smartboard lesson showcases how ratios, fractions, decimals, probabilities, and percentages are all similar ways of looking at the same thing. Each page has a spinner with a different amount of colored slices on it. As you go from many slices to fewer slices, the chance of correctly predicting what color comes up gets much better.

Have students 'bet' classroom rewards like tickets or candy to see who can correctly guess the most colors as you go through the lesson.
