On the move

Thanks to generosity of Chevron through Donors Choose , my math class experienced a new mobile technology, Ollies! Ollies are programmable robots made by  Sphero . We used the app,  Macrolab  to program the Ollies. I modified a lesson from the Sphero website to teach the concepts of measurement and data. The first day, we explored how to program the Ollies and how changing the variables in the program affected what Ollie did. The students recorded data to capture what they were seeing. On day 2 it was time to be more methodical with our data collection. Students only changed one variable at a time. This allowed students to discover the relationship between time and the distance that the Ollie traveled. The students changed the variable of the delay between the roll and stop commands to develop this understanding. There was definitely a lot of excitement and motivation to learn measurement. On Day 3, we analyzed the data recorded from each group. There were some noticeable differences
