Day 156: Probability Boot Camp
Every year it seems my students need additional practice with probability. I was Twitter-lurking again this week and came across Bob Lochel‘s response to a post asking about how people are prepping their kids. Just as David Griswold shared, I had searched for this gem and never did find it. Thanks Bob for sharing!
The questions in this review are thoughtfully put together, mixing in different key concepts and processes for probability. As a class, we talked through the first question together. Then I had the students work on the second question, and did a Navigator quickpoll with the intent to talk about the different answers. I was pleasantly surprised with how many answered correctly (although they didn’t follow directions for sig-figs). But we also were able to analyze the errors: gave the z-score, didn’t subtract from 1…and we followed that up with what might have happened).
As we continued, their success rate improved as is evidenced in this quickpoll results.
I particularly like these two questions as they ask students to put together multiple ideas and solve the problem using a multi-step process…so AP-like!
I really do like to use the quickpoll function of the Navigator to encourage mistake-analysis and engagement. What do you do to help students analyze mistakes?
