1. Geometry · Compose shapes.

1. 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
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

2. Measurement and Data · Investigate questions involving categorical data.

1. Sorting Data into Categories: Organise and represent data with up to three categories by counting objects in each category and sorting categories by quantity
2. Sorting into categories (age 6+): Interpret categorical data by asking and answering questions about totals, how many in each category, and how many more or less one category has than another

3. Measurement and Data · Assign values to time and money.

1. Halves and quarters (age 7+): Solve word problems involving dollar bills, quarters, dimes, nickels, and pennies, using $ and ¢ symbols appropriately
2. Telling Time: Hours and Half Hours: Tell the time to the hour and half past the hour, and draw clock hands to show these times
3. Telling Time: Minutes: Tell and write the time to five minutes, including quarter past and quarter to, and draw clock hands to show these times
4. Telling time to the minute (age 7+): Tell and write time from analogue and digital clocks to the nearest five minutes, using a.m., p.m., and 12-hour and 24-hour notation

4. Numbers and Operations in Base Ten · Subtract multiples of 10 in the range 10-90 from multiples of 10 in the range 10-90 (positive or zero differences).

1. Subtracting multiples of 10: Subtract multiples of 10 (10–90) from multiples of 10 using place value strategies

5. Numbers and Operations in Base Ten · Add within 100 including adding a two-digit number and a one-digit number. Add a two-digit number and a multiple of 10.

1. Adding numbers: Add up to four two-digit numbers using strategies based on place value and properties of operations

6. Numbers and Operations in Base Ten · Understand the two-digits of a two-digit number represent amounts of tens and ones. Understand the following as special cases:

1. A Ten Is Ten Ones: Understand that 10 can be thought of as a bundle of ten ones — called a 'ten'
2. The two digits of a two-digit number: Understand that the two digits of a two-digit number represent amounts of tens and ones

7. Numbers and Operations in Base Ten · Count and represent numbers.

1. Representing Numbers: Identify, represent, and estimate numbers using different representations including the number line
2. Counting forwards and backwards (age 6+): Count forwards and backwards in tens from any number (not just multiples of 10)
3. Counting forwards and backwards: Count forwards and backwards in steps of 3 from 0

8. Operations and Algebraic Thinking · Add and subtract within 20.

1. Fluent adding and subtracting within 10: Fluently add and subtract within 10
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. Fluent adding and subtracting within 20: Fluently add and subtract within 20 using mental strategies; know from memory all sums of two one-digit numbers
