Big Idea: We can draw a picture to divide whole numbers by unit fractions. This lesson introduces students to the concept of dividing a whole number by a unit fraction. This task gives students a situation where they must divide several wholes by fractional pieces. The suggested method of drawing a picture will help them understand that instead of just thinking of it as dividing by a fraction, they should realize that they are trying to find how many groups of that fractional size will fit into the number of wholes given. Using pictures to complete the task may help students develop a concrete and conceptual understanding of dividing whole numbers by unit fractions. The mathematical concepts in this lesson build toward students' future work with division of fractions in sixth grade. Vocabulary: unit fraction, dividend, divisor, quotient, whole number Special Materials: None
