Remember a few weeks ago when I said that our kids tend to be low in Graphing, Probability and Statistics? I’ve been doing lots of hands on activities to help my students really understand probability and statistics, here are a couple of the ones that the kids really liked:
We discussed the probability of spinning each color, something we have done lots of times. Red is 4 out of 8, or 4:8, or 4/8, green is 1 out of 8 and so on… They get that, but they don’t “get” what it means. So, we did an experiment. I give the kids spinners and they used a paperclip to see how our probabilities matched up.
The kids worked in partners and spun 32 times, keeping tally of what color the paper clip landed on. They they determined what the actual probability of spinning each color. We compared their outcomes to our original probability and students were able to see that it was pretty close to what we had predicted. By the end of this activity they really “got” that probability is not just a random number that means nothing, it is actually predicting what would happen.
Another fun activity to learn about probability is the probability of getting the different colors M&Ms. I think they might have liked this one better, mostly because I gave them a cupful of M&Ms :)
Here is the record sheet I made for this activity:
Here is what we did:
I gave each student a Dixie cup full of M&Ms (I used to buy the mini bags of MMs, but now I just buy the big bag and use mini cups…way cheaper!) They separated them into colors and counted them.
Then we determined the probabilities and created graphs of the different colors.
There was lots of learning happening here with probability and graphing. The kids had to reduce their fractions and compare the probabilities. They also had a choose a scale for their graph that worked for the number of M&Ms they had. Hands-on, minds-on!
There you have it! Two hands-on activities that will help kids understand probability and statistics…and give you a little snack (great for a Friday afternoon :)
