What’s the Chance?

IMG_2629Probability is chance or how likely something will happen.  Having a good grasp of fractions, decimals, and percents certainly helps with understanding probability because probability is often expressed as a fraction or decimal or percent. For example, we often hear the chance of rain expressed as a percent such as a 60 % chance or 0% chance.

We’ve been conducting some experiments using spinners and plotting our results on a lineplot. We’ve learned there is a difference between theoretical probability (what we expect to see happen) and experimental probability (what actually happened).

We can show the likeliness that an event can occur by using a probability line where 0 is impossible and 1 is certain.

Of course, you can’t have a probability unit without some engaging and interactive games! So far, we’ve played SKUNK, PIG, and recently a horse race game.

Have a look!
