1. Geometry · SHAPES & SPATIAL UNDERSTANDING

  1. Positional Language: Describe the position of objects using terms such as above, below, beside, in front of, behind, next to

2. Geometry · SOLIDS AROUND US

  1. 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. Sorting 2-D and 3-D shapes: Compare and sort common 2-D and 3-D shapes and everyday objects by their properties
  3. Understanding angles: Recognise angles as a property of shape or a description of a turn
  4. Parallel and perpendicular lines: Identify horizontal and vertical lines and pairs of perpendicular and parallel lines

3. Numbers · DEVELOPING A SENSE OF NUMBERNESS, COUNTING AND OPERATIONS OF NUMBERS 1 - 9 AND ZERO

  1. One-to-one counting: One-to-one correspondence when counting objects: each object is paired with exactly one number name
  2. Counting objects to 20: Count a set of objects to answer 'how many?' for sets up to 20 (arranged in lines, arrays, circles, or scattered)

4. Numbers

  1. Reading and writing numbers to 100: Read and write numerals from 0 to 100
  2. Reading and writing numbers to 120: Count to 120 starting at any number less than 120; read and write numerals to 120
  3. Counting forwards and backwards: Count forwards and backwards in steps of 3 from 0
  4. Representing Addition and Subtraction: Represent addition and subtraction using objects, drawings, and mental images
  5. Reading +, −, and = symbols: Read, write, and interpret the symbols +, −, and = in number sentences
  6. Addition and subtraction strategies: Use counting on and counting back as strategies for addition and subtraction

5. Numbers · NUMBERS FROM (10 - 20)

  1. Reading and writing numbers to 20: Read and write numerals from 0 to 20
  2. Number Words to Twenty: Read and write number words from one to twenty
  3. Tenths: Count up and down in tenths; recognise that tenths arise from dividing an object into 10 equal parts and from dividing one-digit numbers or quantities by 10
  4. Counting in 2s: Count in multiples of 2, 5, and 10 (skip counting)

6. Numbers · ADDITION AND SUBTRACTION (UPTO 20)

  1. Adding and subtracting: Add and subtract one-digit and two-digit numbers to 20, including zero

7. Numbers · NUMBERS FROM 21 - 99

  1. The teen numbers: Understand that the teen numbers (11–19) are composed of ten ones and some further ones (early place value)

8. MENTAL ARITHMETIC

  1. Mental addition and subtraction (age 7+): Mentally add and subtract a three-digit number and ones

9. Money

  1. Coin Values: Recognise and know the value of different coins and notes
  2. Mental and written addition and subtraction: Solve addition and subtraction problems using mental and written methods, including problems involving numbers, quantities, and measures

10. Measurement · LENGTH

  1. Comparing Lengths & Heights: Compare two objects directly by length or height and describe the difference using language such as long, short, tall, longer, shorter, taller, double, half
  2. Measuring length: Order three objects by length and compare the lengths of two objects indirectly using a third object
  3. 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
  4. 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. Estimating Lengths: Estimate lengths using units of inches, feet, centimetres, and metres

11. Measurement · WEIGHT

  1. Measuring mass and weight (age 4+): Compare two objects directly by mass or weight and describe the difference using language such as heavy, light, heavier than, lighter than

12. Measurement · TIME

  1. Comparing durations: Use comparative language for time: quicker, slower, earlier, later
  2. Comparing Time Durations: Compare durations of events and calculate the time taken by particular events or tasks
  3. Ordering Events in Time: Sequence events in chronological order using language such as before, after, next, first, today, yesterday, tomorrow, morning, afternoon, evening
  4. Sequence intervals of time: Compare and sequence intervals of time

13. Data Handling

  1. Measuring & Plotting Lengths: Generate measurement data by measuring lengths to the nearest whole unit and display the data on a line plot

14. Patterns

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