  1. How to Model Fraction Division Georgia Performance Standard: M5N4 Fifth Grade Bob Gregg, Hollydale Elementary School, Cobb County September, 2009

  2. Essential Questions • Unit: How do I work with numbers that are part of a whole? How do I compute with fractions? • Lesson: How many groups of the divisor can I get from the dividend?” • Enduring Understanding: To divide fractions we ask how many groups of one fraction are found in the other fraction.

  3. Vocabulary • Dividend: (the amount you begin with) • Divisor: (the size of each group you will make) • Quotient: (the number of groups of the divisor that are in the dividend) • Compute: (a math process like +, -. x, ÷ • Whole: (one complete thing)

  4. Vocabulary 25 ÷ 5 = 5 Dividend Divisor Quotient 3/4 ÷ 1/4 = N
