## Lesson details

### Key learning points

- When the numerator and denominator are the same, the fraction is equal to 1
- Repeated addition of unit fractions forms a fraction equal to 1
- A number line represents the repeated addition of unit fractions to total 1

### Common misconception

When counting, children might think that 1 comes one step after the numerator and denominator are the same. For example, "...five-sevenths, six-sevenths, seven-sevenths, 1".

As the teacher, count in a given unit fraction and ask the children to stand up, wave or respond in some way when you get to the unit fraction that's equivalent to 1 (when the numerator and denominator are the same).
