Units
Unit 1
Numbers to 1000
Reading, building, comparing and ordering numbers to 1000 as hundreds, tens and ones, including tricky zeros and regrouping (12 tens is 1 hundred and 2 tens).
Curriculum outcome: Operation sense (by Grade 3) · saying, representing, comparing, estimating and placing numbers to 1000
Unit 2
Facts to 20
Building fast, flexible recall of addition and subtraction facts to 20 with strategies like making ten, near doubles, fact families and thinking addition to subtract.
Curriculum outcome: Operation sense (by Grade 3) · quick recall of basic addition and subtraction facts
Unit 3
Add & Subtract
Adding and subtracting 2- and 3-digit numbers by place value, number-line jumps and counting up, plus estimating by rounding to the nearest hundred.
Curriculum outcome: Operation sense (by Grade 3) · adding and subtracting 2- and 3-digit numbers, with mental math and estimation
Unit 4
Multiplication
Understanding multiplication as equal groups, arrays, repeated addition and skip counting. Easier sets use 2s, 5s and 10s; stretch sets go beyond 5 × 5.
Curriculum outcome: Operation sense (by Grade 3) · multiplication to 5 × 5
Unit 5
Division
Understanding division as sharing fairly and as making equal groups, and using multiplication facts to divide (3 × 4 = 12, so 12 ÷ 3 = 4).
Curriculum outcome: Number sense and number theory (by Grade 3) · division as sharing and grouping
Unit 6
Fractions
Naming fractions of a shape, a set and a number line, knowing what the top and bottom numbers mean, and comparing fractions by the size of their parts.
Curriculum outcome: Number sense and number theory (by Grade 3) · fractions as parts of a whole and of a set
Unit 7
Patterns & Equations
Extending increasing and decreasing patterns, describing pattern rules in words and tables, and solving one-step equations like ☐ + 8 = 23.
Curriculum outcome: Patterns and relationships (by Grade 3) · increasing and decreasing patterns, and one-step equations with an unknown
Unit 8
Measuring
Measuring with centimetres and metres, grams and kilograms, millilitres and litres: choosing sensible units, estimating, comparing and solving measurement problems.
Curriculum outcome: Measurement (by Grade 3) · measuring length in centimetres and metres and mass in grams and kilograms
Unit 9
Time
Telling time on an analog clock, working out start and end times, and knowing how seconds, minutes, hours, days, weeks, months and years relate.
Curriculum outcome: Measurement (by Grade 3) · the passage of time in minutes, hours, days, weeks, months and years
Unit 10
3D Objects
Naming 3D objects, counting their faces, edges and vertices, and thinking about how they are built from flat faces or from straws and clay.
Curriculum outcome: Spatial sense (by Grade 3) · describing 3-D objects by the shape of their faces
Unit 11
Graphs & Chance
Reading pictographs and bar graphs where one symbol can stand for one vote or several, and describing how likely outcomes are with spinners, marbles and number cubes.
Curriculum outcome: Data management (by Grade 3) · collecting data, tally marks, line plots and bar graphs
Unit 12
Area & Perimeter
Finding the perimeter (distance around) of rectangles and triangles, finding a missing side, and measuring area in square centimetres and square metres.
Curriculum outcome: Measurement (by Grade 3) · perimeter of regular, irregular and composite shapes
Unit 13
Sorting Polygons
Practises naming polygons by their number of sides and sorting them as regular (all sides and angles equal) or irregular.
Curriculum outcome: Spatial sense (by Grade 3) · naming, describing and sorting polygons
