# Stage 1, mathematics, Year B – Unit 35

This two-week sample Stage 1 unit develops student knowledge and skills in understanding that a fraction can mean half a collection or half a measure.

Students are provided opportunities to:

• engage in meaningful activities using repeated halving to explore halves, quarters and eighths
• create and explore collections of objects that have or have not been divided into halves, quarters and eighths
• investigate division through sharing and grouping a collection, including leftovers.

### Syllabus focus and content groups
