# Stage 1, mathematics, Year B – Unit 31

This sample Stage 1 unit develops students' knowledge, understanding and skills of place value, number representation and data.

In this unit 'Collections of ten are really useful', students are provided with opportunities to:

• investigate the base 10 numerical system
• quantify, organise and represent a variety of collections
• order and compare numbers through different representations
• collect and organise categorical data
• interpret data to ask questions and make informed decisions
• identify simple objects on a map and describe their position in relation to another object
• create and follow instructions along a path from the beginning to the end.
