Hi professor, This is a voki of myself teaching the students how to work with ratios. If you could have the students watch the youtube video first this will give them a basic understanding and introduction into how to work with ratios. Next if you could compare the red, yellow, and green marbles and have them determine what the ratio of each color is left when taken out of the bag this will help the students get a hands on approach to ratios.

For example: If two red marbles are taken out of the larger bag, what is the ratio of red marbles left: Answer ( 1:2 red marbles)
