Maths in Grade 3

Probability of Precipitation

The class began by exploring the language we use to describe the likelihood of things happening, creating a ‘probability line’ with events ranging from impossible to certain (and all between!).

Making a link to our geography topic about Extreme Weather, the pupils then looked at how probability is used in the forecast of rain. They created an experiment, in which they drew blue or yellow counters (representing rainy or dry days respectively) from a jar. Repeating the experiment with varying proportions of blue and yellow counters allowed the ‘probability of rain’ to be more meaningfully understood.

With the ever-changing weather we have been experiencing in recent weeks, the pupils have been able to put their learning to use making good decisions about when to wear their raincoats!
