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?”

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
