Big Ideas: A fraction describes the division of a whole into equal parts. The denominator of a fraction tells how many equal parts the whole or unit is divided into. The numerator of a fraction tells how many equal parts are indicated. A fraction greater than one can be represented using a visual model. This lesson builds on students’ work with representing fraction less than one with visual representations such as pictorial models and number lines. The task presents students with a situation in which they have to create a visual representation of a fraction greater than one. Students will be asked to reason about the size of the fraction to determine the correct number of pizzas to order. This builds towards students’ future work with operations involving fractions greater than one in grades 4-5. Vocabulary: numerator, denominator, unit fraction, mixed number, partition Special Materials: Students should have access to the following materials for this lesson: Pattern blocks (optional) Fraction strips (optional) Fraction tiles/circles (optional)
