This contextualized lesson was designed as part of a science unit on weather, climate, and climate change, with the recognition that an understanding of basic probability and statistics is required to understand the scientific concepts. This lesson could also be used in a math unit on probability to provide a context for students to apply their math skills.

Lesson objectives:

• understand probability as the long run frequency of an event occurring
• identify general probabilities along a spectrum from “impossible” to “certain”
• connect probabilities with benchmark fractions and percentages from 0% to 100%, multiples of 10% only
• identify different terms, symbols, and numbers common to weather reports
• interpret a weather report to make decisions

The lesson includes a lesson plan, as well as student materials/handouts.
