An inspiring resource for learning numeracy

### Work with numbers to explore different ways of solving mathematical scenarios

Numeracy Focus: Developing number sense

This engaging task requires students to arrange nine digits (1-9) to make three 3-digit numbers whose sum is 999.

The investigation builds fluency as students generate different solutions by flexibly interchanging digits to work towards building a total of 999.

The task also encourages reasoning and understanding as students begin to recognise and explain why certain numbers need to appear in certain places.
