1. Data Analysis and Probability

  1. Pictograms and tally charts (age 6+): Read, write, and use the vocabulary of data collection and display — data, tally, tally chart, frequency, frequency table, survey, pictogram, bar chart, axis/axes, scale, label, category, discrete data, continuous data, line graph, pie chart — and apply these terms when collecting, organising, and presenting data
  2. Pictograms and tally charts: Interpret and construct simple pictograms, tally charts, block diagrams, and simple tables

2. Geometric Reasoning

  1. Measuring Perimeters: Measure the perimeter of simple 2-D shapes
  2. Perimeters of polygons: Solve problems involving perimeters of polygons: find perimeter from side lengths, find an unknown side length, and explore rectangles with same perimeter but different areas (or vice versa)
  3. 2-D shapes (age 8+): Identify lines of symmetry in 2-D shapes presented in different orientations; recognise line-symmetric figures and draw lines of symmetry
  4. Classifying shapes by line properties: Classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines, or angles of a specified size; recognise right triangles as a category
  5. Angles in triangles (age 6+): Distinguish defining attributes of shapes (e.g. triangles are closed and three-sided) from non-defining attributes (e.g. colour, orientation, overall size)

3. Fractions

  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

4. Measurement

  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. Calculating with measurements: Measure, compare, add, and subtract lengths (m/cm/mm), mass (kg/g), and volume/capacity (l/ml) using standard units
  4. 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
  5. Estimating Lengths: Estimate lengths using units of inches, feet, centimetres, and metres
  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

5. Algebraic Reasoning

  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
  3. Unknown in Addition & Subtraction: Determine the unknown whole number in an addition or subtraction equation relating three whole numbers
  4. Finding a missing number in addition: Understand subtraction as finding an unknown addend (e.g. 10 − 8 = ? is the same as 8 + ? = 10)
  5. Two-step addition and subtraction problems: Solve addition and subtraction two-step problems in contexts, deciding which operations and methods to use and why

6. Number Sense and Operations

  1. Adding numbers: Add up to four two-digit numbers using strategies based on place value and properties of operations
  2. 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
  3. The three digits of a three-digit number: Understand that the three digits of a three-digit number represent amounts of hundreds, tens, and ones
  4. 10 or 100 More or Less: Find 10 or 100 more or less than a given number up to 1000
  5. Fluent addition and subtraction: Recall and use addition and subtraction facts to 20 fluently, and derive and use related facts up to 100
  6. Rounding to 10, 100, 1000: Round any number to the nearest 10, 100, or 1000
  7. Comparing Large Numbers: Order and compare numbers beyond 1000
  8. Reading and writing numbers to 1000: Read and write numbers to 1000 in numerals, number names, and expanded form
