These are the guided notes for our lesson about wheels and how their sizes affect distance traveled when programming. We complete this lesson before starting the "Moving Forward Challenges" found here:
Moving Forward Challenges
Included in this purchase are the student guided notes and the "answers", or what I use as answers in class.
This took about one 50min class period. Here is what we did the next day:
I created 4 programs "tiny, small, standard, large" that were simple straight forward move blocks and had the students download them to the robots from my computer (so they couldn't see the number of rotations). The name of the programmed matched what wheel they should use for each. So the student would put the "tiny" wheel on their robot and run the "tiny" program. Based on their measurements of wheel's diameter and the distance the robot traveled, their goal was to tell me how many rotations I had programmed each program. I had them do this on large poster sized paper (I used our bulletin board rolls of paper). This way, they could create 1 "starting line" and draw out how for the robot went with each program and do the math right on the paper. If you have more questions about this, please let me know and I'd be happy to share more details!
