CCSS.Math.Content.7.SP.C
The standard
Investigate chance processes and develop, use, and evaluate probability models.
Common Core State Standards for Mathematics
What this standard means
Students need to connect chance events to numbers from 0 to 1, build simple probability models, and use them to predict results. They should compare what a model says should happen with what actually happens in trials or simulations.
Mastery looks like explaining why a probability is reasonable, using fractions, decimals, or percents, and revising a model when results do not fit. Students often get stuck thinking small samples prove a rule, confusing experimental and theoretical probability, or assuming all outcomes are equally likely.
Ways to teach it
- Have students roll two dice 50 times, record sums, then compare their results to a table of all possible outcomes.
- Ask students to write: If a spinner lands on red 70% of the time, what might the spinner look like?
- Show 10 trial results from a bag draw and ask students to choose the most likely bag contents from three options.
- Use weather forecasts to compare a 30% chance of rain with what happens over many days in local data.
