Year 1 Maths Curriculum Australia: What Students Learn and How to Practise
Year 1 Maths extends early number sense into more deliberate strategies. Students begin working with larger quantities, partitioning numbers, skip counting, addition and subtraction, equal groups, measurement, time, shape, position, patterns and data.
What changes in Year 1 Maths?
Children still benefit from concrete materials, but they increasingly connect those models to diagrams and symbols. For example, an addition story can be acted out, shown with counters, represented as a part-part-whole model and finally written as a number sentence. Good practice keeps those representations connected.
Use the curriculum unit as your map
The Year 1 Maths curriculum units separate broad maths into precise learning goals. This avoids the common problem of finding a worksheet labelled “Year 1” that does not match what the child is currently learning. Choose the unit first, then use its topic guide, teacher slide, worksheet, Practice and Test.
Build fluency without losing understanding
Short recall practice is useful, but students should also explain strategies and solve unfamiliar examples. Ask questions such as “How did you know?”, “Can you show it another way?” and “What would change if the number were one more?” This develops flexible number thinking rather than dependence on one memorised procedure.
When to use worksheets
Printable sheets are useful for handwriting, drawing models and showing working. Keep the sheet tied to the current topic. A targeted addition worksheet after an addition lesson provides useful evidence; a random mixed sheet may make it difficult to tell whether an error comes from the new concept or an unrelated skill.
Free Year 1 Maths practice
SkillrHub connects teaching and practice by curriculum unit. Users can move from a concept explanation to a printable activity, online practice and a separate test without searching across multiple sites.

Year 1 Maths curriculum codes at a glance
This guide is linked to the exact Australian Curriculum v9 content descriptions used by SkillrHub. There are 15 Year 1 Maths curriculum codes in this subject. Use the code list below to move from the broad year-level overview to the exact skill a student is learning.
Number
AC9M1N01 — Numbers to 120
recognise, represent and order numbers to at least 120 using physical and virtual materials, numerals, number lines and charts.
AC9M1N02 — Partitioning tens and ones
partition one- and two-digit numbers in different ways using physical and virtual materials, including partitioning two-digit numbers into tens and ones.
AC9M1N03 — Skip counting and equal groups
quantify sets of objects, to at least 120, by partitioning collections into equal groups using number knowledge and skip counting.
AC9M1N04 — Addition and subtraction within 20
add and subtract numbers within 20, using physical and virtual materials, part-part-whole knowledge to 10 and a variety of calculation strategies.
AC9M1N05 — Additive problem solving and money
use mathematical modelling to solve practical problems involving additive situations including simple money transactions; represent the situations with diagrams, physical and virtual materials, and use calculation strategies to solve the problem.
AC9M1N06 — Equal sharing and grouping
use mathematical modelling to solve practical problems involving equal sharing and grouping; represent the situations with diagrams, physical and virtual materials, and use calculation strategies to solve the problem.
Algebra
AC9M1A01 — Skip-counting pattern sequences
recognise, continue and create pattern sequences, with numbers, symbols, shapes and objects, formed by skip counting, initially by twos, fives and tens.
AC9M1A02 — Repeating patterns
recognise, continue and create repeating patterns with numbers, symbols, shapes and objects, identifying the repeating unit.
Measurement
AC9M1M01 — Comparing length, mass, capacity and duration
compare directly and indirectly and order objects and events using attributes of length, mass, capacity and duration, communicating reasoning.
AC9M1M02 — Measuring length with informal units
measure the length of shapes and objects using informal units, recognising that units need to be uniform and used end-to-end.
AC9M1M03 — Time: years, months, weeks, days and hours
describe the duration and sequence of events using years, months, weeks, days and hours.
Space
AC9M1SP01 — Familiar shapes and objects
make, compare and classify familiar shapes; recognise familiar shapes and objects in the environment, identifying the similarities and differences between them.
AC9M1SP02 — Directions and location
give and follow directions to move people and objects to different locations within a space.
Statistics
AC9M1ST01 — Collecting categorical data
acquire and record data for categorical variables in various ways including using digital tools, objects, images, drawings, lists, tally marks and symbols.
AC9M1ST02 — Representing and comparing data
represent collected data for a categorical variable using one-to-one displays and digital tools where appropriate; compare the data using frequencies and discuss the findings.

Free-first learning
Try the free resources first
Before committing to another monthly or yearly learning subscription, use the free curriculum-linked resources available for the student’s current topic. Start with the Topic Guide, use Practice, review mistakes and then take the separate Test.
A larger paid question bank or learning program can be useful, but paying for more volume does not guarantee that a student will use it consistently. If the learner is already working through the free resources and still needs extra tutoring, marking, adaptive practice, reporting or more question volume, compare paid options for that specific need.
Free-first check: establish a consistent Learn → Practice → Test routine before deciding whether an additional paid service offers something the learner will genuinely use.
