Description

“Subtraction” is a compilation of activities designed to introduce subtraction and provide strategies for numbers to 20
and beyond. Initial activities encourage the use of concrete materials to establish the concept of subtraction through
‘real life’ number stories. The activities which follow allow students to consolidate the subtraction concept while providing
a pool of strategies to promote written and mental computation.
The simple format of each task allows students to work independently or in small groups.
Consolidation tasks have been included to allow students to practise strategies they have learnt mentally and in
an abstract written form.
Assessment pages have been included to assist the monitoring of student progress.
These activities are also suitable for inclusion in student portfolios.
The activities included in “Subtraction” will complement the teaching and learning of subtraction in the lower primary
classroom and help students create a solid foundation on which to build further numeration skills.
