The material set up for this one is a bit labour intensive. There are some that require taping multiple sheets together

- Michael Phelps - this is probably the hardest to pull off. We took this image of Phelps and wanted to blow it up so that it's arm span matches his actual arm span of 6'7" (201cm). To do this we changed the contrast so that the face was less recognizable then used the Poster Razer to slice the image up into 8 pieces (this is actually a free program that is great for making large posters out of smaller pieces of paper). We then printed them on 31"x23" poster sheets and then taped them together and laminated them.

- Shaquille O'Neal - Shaq's feet come in two pieces that have to be taped together
- Michael Jordan - No special instructions for the hands
- Height Wall - We have provided for you some samples to include on the height wall, including some really tall and really short ones and some popular culture examples. We encourage you to add your own examples (ones that resonate with your own students). Cut these out to be placed on the height wall for students to see and compare to.
- Other materials that you will need are measuring devices (metre sticks, measuring tapes etc)

- Prior to students arriving in class, tape the feet to the floor at the classroom entrance, tape the hands on the wall where they will be visible, tape the arm span on the wall so there is room for kids to measure up to it and find a spot to make your height wall. The height wall should have a measuring tape on it (or metre sticks) so students can measure themselves but also stick the sample heights of the famous people on the wall to have students compare to them.
- As a Minds On you might want to show this image and ask "How tall would the person be to fit this shoe?"
- Students start by completing p. 4 from TIPS.
- Students record their measurements on p. 5 and as they circulate they can compare their own measurements to those on the walls and floor. Along the way they can make guesses as to who the mystery feet, hands and arm span are.
- Collect students' data
- Ask students to reveal their guesses. Have them discuss why they chose these people.
- Invite students to add there own person to the height wall.
- As an extension, you can collect this data in a spreadsheet or online form. We have created a sample Google form (or use this link http://bit.ly/relationshipform). If you want your own copy, contact us and we will share one with you. Here is a link to the spreadsheet of data. When you use this form be sure to have students put in a unique class identifier so that you can find your class data in our spreadsheet of data.
- You can analyse the data with students using Fathom. (What is the best predictor of your height? Is your foot length the same as your forearm length?)
- Some extension material on Michael Phelps can be found in this Smart Notebook file and this documentary called Miracle Body.

- Scans of the feet and hands (pdf) - note Phelps is light here and you can recognize him
- Scans of arm span posterized (pdf) - this is a darker scan of just the arm span pieces.
