This Mathematics unit covers a range of mental computation strategies for addition.
It consists of 8 lessons of approximately 60-minutes duration.
The sequence of lessons and suggested time frames should be regarded as a guide only; teachers should pace lessons in accordance with the individual learning needs of their class.
An assessment task for monitoring student understanding of the unit objectives is included and will require an additional lesson.
