1. Statistics: The science of collecting, analyzing, visualizing, and interpreting data can inform understanding and decision making. · Skills & Procedures

  1. Pictograms and tally charts: Interpret and construct simple pictograms, tally charts, block diagrams, and simple tables

2. Time: Duration is described and quantified by time. · Skills & Procedures

  1. Comparing Time Durations: Compare durations of events and calculate the time taken by particular events or tasks
  2. Comparing durations: Use comparative language for time: quicker, slower, earlier, later

3. Patterns: Awareness of patterns supports problem solving in various situations. · Skills & Procedures

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

4. Patterns: Awareness of patterns supports problem solving in various situations. · Knowledge

  1. Shape patterns: Look for and use mathematical structure: apply properties of operations, place-value patterns, and relationships between shapes to solve problems efficiently

5. Measurement: Attributes such as length, area, volume, and angle are quantified by measurement. · Skills & Procedures

  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. Estimating Lengths: Estimate lengths using units of inches, feet, centimetres, and metres
  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

6. Measurement: Attributes such as length, area, volume, and angle are quantified by measurement. · Understanding

  1. Measurable Attributes of Objects: Describe and identify measurable attributes of objects such as length, height, weight, and capacity; use comparative language (longer, shorter, heavier, lighter, more, less)

7. Measurement: Attributes such as length, area, volume, and angle are quantified by measurement. · Knowledge

  1. Measuring length (age 6+): Measure the length of an object using same-size length units laid end to end with no gaps or overlaps

8. Geometry: Shapes are defined and related by geometric attributes. · Skills & Procedures

  1. Understanding angles: Recognise angles as a property of shape or a description of a turn
  2. Edges, vertices, and faces: Identify and describe properties of 3-D shapes including the number of edges, vertices, and faces
  3. Transformations on a grid: Represent and carry out geometric transformations on squared paper or a coordinate grid: reflections (in horizontal, vertical, and diagonal mirror lines, including the axes), translations (described as a vector or as left/right/up/down moves), and rotations (90° or 180° about a stated centre point); describe each transformation precisely using the correct language; identify which transformation maps one shape onto its image by comparing position, orientation, and size
  4. Sorting 2-D and 3-D shapes: Compare and sort common 2-D and 3-D shapes and everyday objects by their properties

9. Geometry: Shapes are defined and related by geometric attributes. · Understanding

  1. Transformations on a Grid: Identify, describe, and represent the position of a shape following a reflection or translation using appropriate language; know that the shape has not changed

10. Geometry: Shapes are defined and related by geometric attributes. · Knowledge

  1. 2-D shapes (age 6+): Identify and describe properties of 2-D shapes including the number of sides and line symmetry in a vertical line

11. Number: Quantity is measured with numbers that enable counting, labelling, comparing, and operating. · Skills & Procedures

  1. Fractions of amounts: Recognise, find, name, and write fractions 1/3, 1/4, 2/4, and 3/4 of a length, shape, set of objects, or quantity
  2. Fractions of a whole: Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts; understand a/b as a parts of size 1/b
  3. Unit fractions: Recognise, find, and write fractions of a discrete set of objects: unit fractions and non-unit fractions with small denominators
  4. Adding numbers: Add up to four two-digit numbers using strategies based on place value and properties of operations
  5. Division as equal sharing: Understand division as sharing equally into groups or as grouping (how many groups of a given size can be made)
