Is It Possible: Estimating Measurement

In this activity, learners will decide together on a question about how far, long or high the group could reach together. For younger learners, choose something a few learners can easily test out: If we joined hands, could we circle the tree? For a medium level of challenge, pick something the whole group can test out: If we lie head to foot, could we reach across the playground? Older learners investigate by estimating: If we stood on one another’s shoulders, could we reach the top of the building? Learners make predictions based on mental calculations and estimates of size; then, if possible, they try it out. [Activity is publicly available through a web crawler capture on Archive.org.]
