Learning Intention: Understand the denominators of unit fractions

Objective: By the end of the lesson, students will be able to identify the denominator of common unit fractions.

Materials: Whiteboard, whiteboard marker, fraction tiles, fraction number lines

Procedure:

1. Introduce the topic by writing the learning intention on the board - “Understand the denominators of unit fractions”. Explain what a unit fraction is and how it is defined.

2. Have the students create a fraction number line using the fraction tiles. Explain that the denominators of unit fractions will always be the number of parts on the fraction number line.

3. As a class, name common unit fractions and their denominators. Discuss why the denominators of unit fractions are always whole numbers.

4. Check for understanding by using an analogy with a pizza: explain that unit fractions are like slices of pizza and the denominator of a unit fraction is equivalent to the total number of slices.

5. Hand out fraction number lines and have the students fill it in with the different unit fractions and their denominators.

6. Have students complete a worksheet or a written exercise to check their understanding.

7. Wrap up the lesson by having a discussion about the importance of understanding unit fractions and denominators.
