1. Geometric & Spatial Reasoning · Draw and partition shapes and other objects with specific attributes, and conduct observations of everyday items and structures to identify how shapes exist in the worl

  1. Fractions as parts of shapes: Partition shapes into parts with equal areas and express the area of each part as a unit fraction of the whole
  2. Halves & Quarters of Shapes: Partition circles and rectangles into two and four equal shares and describe them using the words halves, fourths, and quarters
  3. Patterns & Sequences: Order and arrange combinations of mathematical objects in patterns and sequences
  4. Sorting 2-D and 3-D shapes: Compare and sort common 2-D and 3-D shapes and everyday objects by their properties

2. Measurement & Data Reasoning · Solve real-life problems involving 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: Minutes: Tell and write the time to five minutes, including quarter past and quarter to, and draw clock hands to show these times
  3. 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

3. Measurement & Data Reasoning · Estimate and measure the lengths of objects and distance to solve problems found in real-life using standard units of measurement, including inches, feet, and yards and

  1. 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
  2. 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
  3. Measuring & Plotting Lengths: Generate measurement data by measuring lengths to the nearest whole unit and display the data on a line plot
  4. Estimating Lengths: Estimate lengths using units of inches, feet, centimetres, and metres

4. Patterning & Algebraic Reasoning · Identify, describe, extend, and create repeating patterns, growing patterns, and shrinking patterns.

  1. Extending Table Patterns: Recognise and use repeated reasoning to generalise: extend multiplication table patterns, derive unknown facts from known ones, and describe rules for sequences

5. Numerical Reasoning · Work with equal groups to gain foundations for multiplication through real-life, mathematical problems.

  1. Arrays for multiplication (age 7+): Use addition to find the total number of objects arranged in rectangular arrays with up to 5 rows and 5 columns; write an equation to express the total as a sum of equal addends
  2. Odd or Even: Determine whether a group of objects (up to 20) has an odd or even number of members

6. Numerical Reasoning · Apply multiple part-whole strategies, properties of operations and place value understanding to solve real-life, mathematical problems involving addition and subtraction within 1

  1. Adding within 100: Add within 100 using strategies based on place value, including adding a two-digit and one-digit number, and a two-digit and a multiple of 10
  2. Fluent adding and subtracting within 100: Fluently add and subtract within 100 using strategies based on place value, properties of operations, and the relationship between addition and subtraction
  3. Addition and subtraction strategies (age 7+): Explain why addition and subtraction strategies work, using place value and the properties of operations
  4. Adding numbers: Add up to four two-digit numbers using strategies based on place value and properties of operations
  5. 10 or 100 More or Less: Find 10 or 100 more or less than a given number up to 1000

7. Numerical Reasoning · Using the place value structure, explore the count sequences to represent, read, write, and compare numerical values to 1000 and describe basic place-value relationships and stru

  1. Ordering Numbers to 1000: Compare and order numbers up to 1000 using >, =, and < symbols, based on place-value understanding
  2. Place value of each digit: Recognise the place value of each digit in a four-digit number (thousands, hundreds, tens, and ones)
