1. Data & Probability · Collect, organize, and interpret data.

  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
  3. Picture & Bar Graphs: Draw a picture graph and a bar graph (with single-unit scale) to represent a data set with up to four categories; solve put-together, take-apart, and compare problems using information presented in a bar graph

2. Geometry & Measurement · Tell time to the quarter hour.

  1. 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
  2. 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. Telling time to the minute (age 8+): Tell and write time to the nearest minute using analogue and digital clocks

3. Geometry & Measurement · Understand length as a measurable attribute and explore capacity.

  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)
  2. 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
  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. Geometry & Measurement · Analyze attributes of two- and three-dimensional figures and develop generalizations about their properties.

  1. Understanding angles: Recognise angles as a property of shape or a description of a turn
  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. 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

5. Algebraic Reasoning & Algebra · Use number sentences involving unknowns to represent and solve realworld and mathematical problems.

  1. Connecting Representations: Move between real-world situations, drawings, and number sentences, explaining how each representation connects to the others (quantitative reasoning)

6. Algebraic Reasoning & Algebra · Describe the relationship found in patterns to solve real-world and mathematical problems.

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

7. Numbers & Operations · Determine the value of a set of coins.

  1. Adding money and giving change: Find different combinations of coins that equal the same amount of money
  2. Halves and quarters (age 7+): Solve word problems involving dollar bills, quarters, dimes, nickels, and pennies, using $ and ¢ symbols appropriately

8. Numbers & Operations · Explore the foundational ideas of fractions.

  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. 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
  4. Unit fractions: Recognise, find, and write fractions of a discrete set of objects: unit fractions and non-unit fractions with small denominators
  5. Fractions on a number line: Recognise and use fractions as numbers: place unit fractions and non-unit fractions with small denominators on a number line

9. Numbers & Operations · Add and subtract one- and two-digit numbers in real-world and mathematical problems.

  1. Adding numbers: Add up to four two-digit numbers using strategies based on place value and properties of operations
  2. Adding two two-digit numbers: Add and subtract two two-digit numbers using concrete objects, pictorial representations, and mental methods
  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
