Math
In Real Life Math, Will threw balls toward targets to explore the probability of accuracy. He connected repeated attempts with the chance of a successful hit, considering accuracy as an outcome that could be observed across throws. The activity helped him see how probability can describe performance in a practical setting rather than only in an abstract problem. Will practiced approaching an everyday task as a way to investigate mathematical likelihood.
Tips
Tips Extend the activity by having Will record each throw as a hit or miss, then calculate the proportion of hits; repeat the same number of throws from different distances and compare the results; invite him to predict how many hits he might make in a new round and discuss how the evidence compares with his prediction; and use a simple target diagram to explore whether aiming at different regions changes the observed accuracy.

Learning Standards
- Virginia SOL Mathematics, Grade 9 — A.ST.1.a: The target-throw activity can lead to an investigative question about accuracy and chance.
- A.ST.1.b: A follow-up can identify variables such as throw outcome and number of attempts.
- A.ST.1.c: Recording outcomes over repeated throws provides a way to collect data.
- A.ST.1.g: Calculating and discussing the observed hit rate can support communicating results in response to the investigative question.
