Math
In the Probability/Statistics “Real World Math” class, Will used a deck of cards to explore probability through different prompts. He worked with theoretical probability, considering how likely a card outcome should be based on the possible outcomes in the deck, and experimental probability, using results from trials to examine observed likelihood. Comparing these two approaches helped Will see how mathematical predictions relate to outcomes produced by an experiment. This activity developed his ability to reason about chance and interpret probability in a familiar real-world context.
Tips
Tips Extend Will’s learning by having him predict and record the likelihood of several card outcomes before testing each one. He could repeat the same card experiment with different numbers of trials, then compare how the experimental results change as the sample grows. Invite him to create a simple table or graph of predicted and observed probabilities and explain any differences. To make the investigation creative, ask him to invent a fair card-based game and justify its rules using probability.

Learning Standards
- Virginia Mathematics SOL—Algebra I, A.EO.1 (partial connection): The activity involved mathematical reasoning, but the stated standard focuses on simplifying and evaluating algebraic expressions; no direct match to its listed skills is established by the activity description.
- Virginia Mathematics SOL—Grade 5, 5.PFA.1 (partial connection): Recording and comparing repeated outcomes could support describing patterns, although numerical patterns or input-output relationships were not specifically described.
- Probability and statistics: Will directly explored theoretical and experimental probability with card-based prompts. The supplied SOL framework does not list a specific probability standard for his grade, so no closer code can be confirmed from the provided information.
