1. Statistics and Probability (Data Analysis)

1. Pictograms and tally charts: Interpret and construct simple pictograms, tally charts, block diagrams, and simple tables
2. Measuring & Plotting Lengths: Generate measurement data by measuring lengths to the nearest whole unit and display the data on a line plot

2. Shape and Space

1. 2-D shapes: Recognise and name common 2-D shapes (circles, triangles, rectangles including squares)
2. Composing Shapes: Compose two-dimensional shapes (rectangles, squares, trapezoids, triangles, half-circles, quarter-circles) to create composite shapes, and compose new shapes from the composite shape
3. 2-D shapes (age 7+): Draw 2-D shapes and make 3-D shapes using modelling materials; recognise 3-D shapes in different orientations and describe them
4. Building with 3-D Shapes: Compose three-dimensional shapes (cubes, right rectangular prisms, right circular cones, right circular cylinders) and create composite shapes; build new shapes from component shapes
5. Sorting 2-D and 3-D shapes: Compare and sort common 2-D and 3-D shapes and everyday objects by their properties
6. Measuring with different units: Measure the length of an object using two different length units and describe how the measurements relate to the size of the unit chosen
7. Comparing and ordering measurements: Compare and order lengths, mass, and capacity and record results using >, <, and =
8. Measuring length: Order three objects by length and compare the lengths of two objects indirectly using a third object
9. Comparing lengths by measuring: Measure to determine how much longer one object is than another, expressing the length difference in terms of a standard length unit
10. Days, Weeks, Months & Years: Recognise and use language relating to dates, including days of the week, weeks, months, and years

3. Patterns and Relations (Patterns)

1. Patterns & Sequences: Order and arrange combinations of mathematical objects in patterns and sequences

4. Number

1. Addition and subtraction strategies: Use counting on and counting back as strategies for addition and subtraction
2. Addition and subtraction within 20: Add and subtract within 20 using strategies such as making ten, decomposing a number leading to ten, and using known facts
3. Adding numbers: Add up to four two-digit numbers using strategies based on place value and properties of operations
4. Numbers on a number line: Represent whole numbers as lengths on a number line and represent sums and differences within 100 on a number line diagram
5. Adding two two-digit numbers: Add and subtract two two-digit numbers using concrete objects, pictorial representations, and mental methods
6. Place Value to 1000: Solve number problems and practical problems involving place value of numbers up to 1000
7. Estimating by rounding: Estimate the answer to a calculation and use inverse operations to check answers; apply to increasingly large numbers using rounding and inverse reasoning
8. Comparing Large Numbers: Order and compare numbers beyond 1000
9. Representing numbers with objects: Represent numbers using objects, pictorial representations, and the number line
10. Counting in 2s: Count in multiples of 2, 5, and 10 (skip counting)
11. Odd or Even: Determine whether a group of objects (up to 20) has an odd or even number of members
