Mathematics:

The Number StrandEarly Stage One and Stage One

Presented byConnie Sawyer & Emily HewittMathematics Information Session1The K-6 Mathematics Syllabus is structured using:one process strandWorking Mathematicallyand five content strandsNumberPatterns and AlgebraDataMeasurementSpace and GeometryThe K-6 Mathematics Syllabus2The Number strand encompasses five sub-strands:Whole NumbersAddition and SubtractionMultiplication and DivisionFractions and DecimalsChance (no outcomes for ES1)The Number strand3The Best Start Numeracy Assessment provides Early Stage One teachers with a starting point. It helps teachers identify the numeracy knowledge and skills that each child brings to school as they enter Kindergarten. It enables teachers to plan appropriate learning experiences that make connections with existing mathematical understanding. Prior learning indicates pathways for further learning.

Where do we begin?4NumberEarly Stage One5Whole NumbersOutcome: Counts to 30, and orders, reads and represents numbers in the range 0 to 20

Count forwards to 30, from a given numberCount backwards from a given number, in the range 0 to 20Compare, order, read and represent numbers to at least 20Read and use the ordinal names to at least tenthUse the language of money6Learning Tools:

9Addition and SubtractionOutcome: Combines, separates and compares collections of objects, describes using everyday language and records using informal methods

Combine groups to model additionTake part of a group away to model subtractionRecord addition and subtraction informally10

12Multiplication and DivisionOutcome: Groups, shares and counts collections of objects, describes using everyday language and records using informal methods

Model equal groups or rowsGroup and share collections of objects equallyRecord addition and subtraction informally13

14

15Fractions and DecimalsOutcome: Describes halves, encountered in everyday contexts, as two equal parts of an object

Divide an object into two equal partsRecognise and describe halves16

What is 10 more than a number?
