Mapping the math of luck: conceptual walkthrough

Section role: supports the 'Mapping the Math of Luck' section while the teacher formalizes mathematical definitions on the whiteboard and bridges them with English modal verbs. Slides: (1) Title — 'Mapping the Math of Luck'; (2) Ratio Definition — bullets: expressing comparison as A:B or A/B, using the marble bag scenario data (3 Red to 12 total); (3) Proportion Equality — bullets: defining proportion as equal ratios, showing the scaling example 5/12 = 25/60 from the previous challenge; (4) Probability Formula — bullets: favorable outcomes divided by total possible outcomes; (5) Likelihood Scale — visual of the 0 to 1 scale, linking 0 to 'won't happen', 0.5 to 'might happen', and 1 to 'will happen'; (6) Dispelling Misconceptions — bullets: probability predicts likelihood, it does not guarantee an outcome; Closing slide: 'How does our calculation change if we add 4 more blue marbles?' — hands control back to the teacher for discussion.
