Core Skills Analysis
Mathematics
The 15‑year‑old completed a series of interactive modules on the Brilliant platform that focused on probability, chance, and percentages. They learned how to calculate the likelihood of single and combined events, express probabilities as fractions, decimals, and percentages, and apply the rules of complementary and independent events. In the percentages section, they practiced converting between fractions, decimals, and percent form, determining percentage increase or decrease, and solving real‑world word problems such as discounts and tax calculations. By the end of the activity, they demonstrated proficiency in manipulating ratios and interpreting probabilistic outcomes in everyday contexts.
Digital Literacy
Through the self‑directed work on Brilliant, the student navigated a digital learning environment, selecting appropriate modules, interpreting on‑screen prompts, and using built‑in feedback to guide their problem‑solving strategies. They engaged with interactive visualisations that illustrated probability trees and percent bar models, strengthening their ability to read and create digital representations of data. The experience also required time‑management and metacognitive reflection as they monitored their progress and adjusted their approach based on instant performance analytics.
Tips
To deepen understanding, have the student design a simple board game that requires calculating odds for different moves and then play it to test their predictions. Next, create a mini‑budget project where they must apply percentage calculations to track income, expenses, and savings over a month. Incorporate a real‑world data set—such as sports statistics or election polls—and ask them to compute probabilities and present findings with digital graphs. Finally, encourage them to teach a peer or family member a tricky probability problem, reinforcing mastery through explanation.
