Big Ideas: Non-unit fractions can be thought of as the numerator times the unit fraction with the same denominator. There is an analogy between fractions and whole numbers, such that 3 x ⅖ can be thought of as ⅖ +⅖ + ⅖ and as (3 x 2)/5 The task in this lesson requires students to interpret the meaning of multiplication beyond whole numbers. Students will see that when multiplying whole numbers by fractions, they can employ their understandings of what multiplication means with whole numbers. For example, they will use an area model to think of a variety of student generated equations with fractions to represent the problem. Vocabulary: multiple, equation, factors, products, numerator, denominator, fraction, whole number, area Special Materials: Pattern Blocks Pattern Block grid paper
