Big Ideas: A fraction describes the division of a whole into equal parts. The denominator describes how many equal parts the whole or unit is divided into, and the numerator describes how many equal parts are indicated. Fractions can be represented using models. This lesson builds on students' work visual representations. In this lesson, students will strengthen their understanding of fractions by focusing on fractions with a numerator other than one. The task requires students to demonstrate their knowledge of what a fraction is by dividing the shape into equal shares. Students will create their own cake scenario and represent certain fractions by drawing a visual model. Students will focus on how to represent fractions greater than one. This lesson builds towards future work with fraction sense and developing understanding of non-unit fractions and mixed numbers. Vocabulary: numerator, denominator, unit fraction, partition, equal Special Materials: Students should have access to the following materials for this lesson: Pattern blocks (optional) Fraction strips (optional) Two sided counters (optional)
