Students needed to get their robot to deliver mail to specific locations. The teachers and I wanted to have them to estimate and check using rotations as the unit (1 wheel rotation is ~ 17 cm). The teachers and students took lots of pictures and described what they did:
The buzz was everywhere as we set off in hopes of programming our robots to deliver the mail throughout our ‘communities.’ Tying in with connections to our inquiry study “Our Never-ending Story – What’s in the World Around Us?” and Mathematics, we challenged the students’ estimation abilities by focusing on decimal rotations in programming. How can we make the robot turn, travel and deliver the mail exactly the way we want it to without having to use whole values that would lead to inaccuracies in travel? Students discovered that by placing markers along their routes they could make plausible estimations for how to program their machines with less frustration.
