Unit 72
This math unit focuses on developing student proficiency with factorials, starting from the basics and progressing to more advanced applications within probability and combinatorial contexts. Initially, the unit introduces students to converting factorials into multiplication strings and calculating factorial values. Students are then guided through recognizing and converting multiplication strings back into factorials, an essential skill for understanding permutations and combinations. Further into the unit, more complex operations involving factorials are taught, such as simplifying factorial expressions through division and understanding the equivalent values of factorial divisions. By converting factorial multiplication strings to divisions, students enhance their ability to manipulate and rationalize factorial expressions crucial for accurate probability computations. Towards the later part of the unit, students engage with a variety of factorial calculations, including those with simpler forms, and gradually move to manipulating expressions involving brackets and mixed operations. This progression sharpens their skills in handling complex factorial-based calculations, underpinning higher-level studies in statistics and probability.Skills you will learn include:
