First Class On Probability!

For our first lesson on probability we did an experiment with gold fish, or at least we would have but the goldfish had sadly been thrown away! So, we had to just use our imagination!



Activity Name:” Healthy Fish”

What you need: Colored goldfish in a bag that will represent either healthy or sick fish.

Once all your groups have the goldfish you than need to count and see how many fish you have that are healthy or sick. The green ones are sick and the other colors are healthy fish.

After counting how many fish you have, or in my classes’ case being told how many fish you have, you need to compute different kinds of probabilities. Such as, computing “the probability that a fish in your sample is healthy.”

When teaching and trying to understand probability it is so much easier to actually have some kind of item, like goldfish, that you can actually feel and move around. For me, it makes it so much less confusing!
