# Stage 1, mathematics, Year A – Unit 11

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

Students are provided with opportunities to:

• use representations of groups of 10
• quantify, organise and represent large collections
• explore place value through partitioning
• demonstrate equivalence
• compare numbers through different representations
• find patterns when representing large numbers
• see and explore that an analog clock is made by curving a number line
• use a grid structure to describe the paths between numbers.
