Outcomes
MAE-CSQ-01 reasons about number relations to model addition and subtraction by combining and separating, and comparing collectionsMAE-CSQ-02 represents the relations between the parts that form the whole, with numbers up to 10Content dot points
Each dot point has its own page with resources matched to it.
Model additive relations and compare quantities
- Identify situations in which addition and subtraction may be applied
- Combine two or more groups of objects to model addition, identifying the relationship between the parts and the whole
- Separate and take away part of a group of objects to model subtraction
- Use concrete materials or fingers to model and solve addition and subtraction questions, counting forwards or backwards by ones as necessary
- Compare two groups of objects to determine how many more (Reasons about quantity)
Identify part–whole relationships in numbers up to 10
- Use visual representations of numbers to assist with combining and separating quantities, identifying the relationship between the quantities
- Describe the action of combining, separating and comparing
- Use five as a reference in forming numbers from six to ten
- Create, model and recognise combinations for numbers up to ten (Reasons about relations)
- Count by ones to find the total or difference
- Use drawings, words and numerals to record addition and subtraction, and explain their thinking (Reasons about relations)
