Essential Question for students (objective): How can you use proportions in real world problems using measurement conversions? Supplies: video (length 0:50), note-maker

Instructional Format: Video, student problem-solving, group or individual work

Lesson Description: There are many ways to use this video in your math class. I filmed it with the express purpose of using ratios and proportions with measurement conversions in a real-world setting. This is also a great opportunity to apply proportions in a multi-step problem.

1) You can show this video (0:50) at the beginning of a unit on proportions (dimensional analysis) as a hook that will keep the students interested in learning about proportions. You can have them work on the problem at the end of daily lessons (or once a week) armed with new knowledge that they are exploring in class. Students use the note-maker to help record their problem-solving work. Or you could revisit the video at the end of the unit as a formative check to see what the students have learned about using proportions and whether they can apply that knowledge.

2) You could show this video as a warm-up activity after the students have learned some basic proportion computation. It is a great way to show context to math that connects to the world we live in.
