Teaching circumference and diameter conversions? Teaching graphing or data literacy? If you schools has any trees, this hands-on outdoor activity is for you! All you need are flexible measuring tapes, chalk, and this sheet for students to gain real-life experience converting circumference to diameter. It is also a great lab for learning graphing! I use it when teaching variability and frequency graphs (dot plots, box plots, histograms). Please download the
Free Tree Measurement Data for students to practice with more data. The Graph Choice Chart Worksheet is also helpful.
