Teacher's Notes

These exercises and activities are for students to use independently of the teacher to practice number properties.

### Number Framework domain and stage:

Fractions stages 7 to 8. Advanced multiplicative to advanced proportional

### Curriculum reference:

Number, levels 4 and 5

### Numeracy Project book reference:

These activities can be used to follow the teaching episodes based on, **Book 7, pages 31 to 33** and are for those students who are able to use the associated number properties.

### Prior knowledge. Students should be able to:

- Simplify fractions
- Convert fractions to decimals
- Understand the double number line and how to use it proportionately

### During these activities, students will meet:

- Converting fractions to percentages using the double number line

### Background

Note that this strategy is nice when the number is easy to convert to 100, but becomes much harder to use on fractions like . Even can be problematic, especially if students do not simplify the fraction first, so some discussion is needed about this before setting the activity.
