Fraction Laws and Division: Walkthrough

Section role: supports Section 3 to formalize the student discoveries from the garden challenge into mathematical laws and introduce division of unit fractions. Slides: (1) Title - 'Formalizing Fraction Operations'; (2) Garden Area Review - bullets: showing 2/3 times 3/4 equals 6/12, explaining why multiplying denominators sets the new unit fraction size; (3) Multiplication Rule - bullets: numerator times numerator, denominator times denominator formula; (4) Division Story Context - bullets: 1/3 of a pizza shared among 4 people; (5) Visual Proof of Division - bullets: demonstrating (1/3) divided by 4 equals 1/12 using area and multiplicative inverse; (6) Core Identity - bullets: defining a/b equals a times (1/b) as a foundational principle. Closing slide: 'How does knowing that division is the inverse of multiplication help us solve complex fraction problems?' - sets up the individual verification in Section 4.
