Unit 9

This math unit progresses from fundamental to more intricate probability calculations. Initially, students practice calculating probabilities of specific outcomes using dice and coins, expressing results in fractions and decimals. The unit advances into scenarios involving multiple probabilities and dependent events, with problems framed around spinners, cards, and shapes to enhance real-world applicability. As students progress, they calculate probabilities for sequences of events, such as drawing cards or shapes in specific orders and conditions, represented through equations and percentages. This gradual increase in complexity helps students build a robust understanding of basic probability concepts, practice essential counting principles, and apply these skills to complex, multi-event scenarios using different representations like fractions, decimals, and percentages.
