Students will be able to write and solve word problems that require the multiplication of fractions by whole numbers.
Pose the following word problem to students: Sally ate 1/8 of a pie. Suzy ate 3 times more than Sally. How much of the pie did Suzy eat?
Have students talk with each other about how they would solve this word problem.
Call on some students to share how they would solve the problem. Explain that students could use either multiplication or addition. Remind students that repeated addition is another form of multiplying, so multiplication is the most efficient way to solve this problem.
Explain that today, students will be learning how to multiply fractions by whole numbers. They will also be writing their own word problems that require this type of math.
