Dimensional Analysis Shape Cards Activity

I am a huge fan of these dimensional analysis shape cards that were created by Kathryn Freed to introduce students to the concept of converting units. I have used them with both my physical science students and my chemistry students.

To use them, I give students a starting shape and an ending shape. They have to determine a way to “convert” from one shape to another.

I especially like that the cards can be flipped over, just as conversion factors can be flipped over when doing dimensional analysis.
