Can you ever be truly prepared? I have come to the conclusion there are only varying degrees of preparation and the rest is how much uncertainty can be tolerated. Monday some of my students will arrive for lunch and to begin our summer program. I do not know exactly how many will come, it could be the full 70 that expressed interest or more or possibly fewer. I cleaned the computer lab, printed passwords and usernames to facilitate logging in, I planned some off-line activities for younger students and printed registration forms. I am prepared to the point that I can accept the uncertainty as excitement about a new venture.
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
