Today we did one of my favorite activities- Skin and Guts. It is from an AIMS book- Effects of Changing Lengths. I love AIMS products and I highly suggest checking them out if you haven’t already.

The kids are given nets of 3 rectangular prisms. They create 3 people- One Man, Two Man, and Three Man.

In groups the kids measured the height of each man, the belt length of each man, the area of the face of each man, the area of the skins (surface area), and the guts (volume). Then they looked at the scale factors of the length measurements (height and belt length) vs the area measurements (area of face and skins) vs the body measurements (guts).

I love this activity because the kids get hands on measuring experience and they can visualize how changing one dimension vs two dimensions vs three dimensions really changes the numbers.

I also had one of those great teaching days when I felt like so many connections were made and the kids were working on an activity that provided them with exactly the right amount of challenge that they could handle but yet kept them interested and working. So many kids told me how much they loved this activity, which is also a plus!

It was from the Effects of Changing Lines book, but it looks like it is no longer available! Boo!

I haven’t been able to find this book to do this lesson. It looks great. The AIMS store doesn’t show it available or I’m not finding it. Can you steer me?

It looks like it is no longer available!

This looks like a great activity. However, the book is no longer available.

That is so sad! I will email them and ask about it!

Where did you get the printable sheets for this activity?

One of the AIMS books, but it is no longer available 😦

Did you get a reply from Aims? If not, can you make a PDF of it?
