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 5 - 6, early additive part-whole to advanced additive

### Curriculum reference:

Number, level 3

### Numeracy Project book reference:

These activities can be used to follow the teaching episodes based on, **Book 7, pages 14 and 15** and are for those students who are able to use the associated number properties.

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

- Find a simple fraction of an amount using addition facts

### During these activities, students will meet:

- Using multiplication facts to find a simple fraction of an amount

### Background

Remember that students who have not reached stage 6 in the "basic facts" domain have not learned all of their basic multiplication facts, so a multiplicative strategy based purely on the numbers may not work for all students. Keeping to simpler numbers has been attempted in the activities for this reason.
