We all know it is best to learn

Math by using our hands (interactive stuff) and using our heads (critical thinking). But how about if we also use our faces?

The students would use rulers to measure sms service a partner’s facial features, then put the measurements into unit rates to see how close they were to the Greek Golden Ratio. It was a really fun activity, but definitely one that would benefit from a technology update.

(Hint: Middle schoolers plus wooden rulers plus classmates’ faces are not always a good mix.)

So, I have updated the activity with the use of Google Docs, webcams, and a digital ruler web app. See below for all the details on how the “Golden Ratio Face” project works, as well as access to all the needed templates and resources.

The focus of the

Golden Ratio Face” activity is to teach about unit rates by using the Greek idea of perfection through the Golden Ratio.

For example, the height of your head, when  compared to the width of your head, should be about 1.62 to 1. Many other features on the face could be compared the same way.

In this activity students will do the following

Add a picture of their bz lists face (or someone else’s) via their webcam or by inserting an image.

Use a digital ruler web app to measure 12 different facial features.

As we continue to move more into digital activities for our students, some things that often stay non-digital are physical manipulatives including rulers and protractors. Certainly there is nothing wrong with using wooden or plastic rulers and protractors (our students do need to know how to use them) but there are also benefits to having online alternatives
