Multiplication and Division of Fractions: Lesson 5 (Multiplying a Fraction by a Whole Number)

Match Fishtank 50 min(s)

In this lesson, students will relate multiplication of a fraction by a whole number to multiplication of a whole number by a fraction and use this to develop a general method to multiply any fraction by any whole number (or vice versa). Use this generalized method to compute products of whole numbers and fractions or fractions and whole numbers. Before computing a product of a whole number and a fraction, predict whether the product will be greater than, equal to, or less than the whole number (as an introduction to the idea of scaling).
