# Stage 1, mathematics, Year A – Unit 20

This two-week unit develops student knowledge, understanding and skills that problems can be solved and represented in different ways.

In this unit, 'Problems can be solved and represented in different ways', students are provided opportunities to:

• solve modelled problems concretely, pictorially, and symbolically to help develop fluency
• count and order a collection of items
• place numbers accurately on a number line
• use symbols to represent a story.
