Apply and extend previous understandings of multiplication to multiply a fraction by a whole number.
Understand that a fraction, such as 4/7, is equal to 4 * (1/7). That is, 4/7 is equal to 4 pieces, each of size 1/7.
Understand that 2 * (3/7) = 6 * (1/7).
Solve word problems involving multiplication of a fraction by a whole number. Start with manipulatives and pictures, then gradually move away from them. Conclude by giving your students this challenge. After they've attempted the problem, show them the video, as it explains the solution.
