Unit 26

This math unit starts with basic permutation concepts, teaching students to calculate the number of ways to order cards and letters without repetition, gradually advancing from three to five items. As the unit progresses, it introduces problems involving spinning a labeled spinner, first teaching students to calculate specific outcomes in multiple formats (equations, fractions, percentages), and then broadening to include calculations for any occurrence within two spins, expressed in various numerical forms. The unit deepens understanding by exploring factorial notation in probability scenarios, leading to advanced applications in combinatorics. The skills progress from foundational permutations to complex factorial operations and probability calculations involving multiple scenarios and various forms of numerical expression, reinforcing the understanding and application of probability through diverse practical examples and increasingly complex mathematical operations. Toward the end, the unit integrates the concepts of factorials more directly, culminating in practical applications related to card-drawing probabilities.
