The journey
The confidence journey starts with understanding.
Every stage builds on the one before it. Nothing is skipped, and nothing is rushed to get to an exam.
Understand the idea
Visual models and plain language, before any question is asked.
Build fluency
Practice sequenced so skills become reliable, not just familiar.
Explain the thinking
Worked examples show the method, not only the answer.
Practise with feedback
Answers marked as they go, with the reasoning laid out.
Go deeper over time
Four difficulty tiers per unit, from fluency to genuine challenge.
Meet senior maths ready
Full-length exam-style papers, in your state's own credential.
Inside PiGrids
One learning journey. Clear at every step.
The same six moves, whether the learner is in their first year of school or their last.
See the idea before solving the question.
Visual models and clear language explain what the maths means, so a new concept starts as something to understand rather than a rule to remember.
Builds understanding
Learn the method one step at a time.
Worked examples set out the reasoning line by line, so a student follows the thinking instead of copying an answer.
Builds strategy
Practise at the right level, four tiers deep.
About 150 questions per unit from Foundation to Year 6, and 400 per unit from Year 7 to Year 12, across four difficulty tiers. Typed answers are marked automatically.
Builds fluency
Find the gaps before they matter.
A short diagnostic at the start of every chapter shows which ideas are secure and which need another look. Free on every plan.
Builds resilience
Know the next helpful step.
A parent dashboard in plain words: what each child is working on, what they finished, how the week went, and what to do next. Up to five children on one account.
Builds confidence
Help the moment it is needed, not before.
Every question carries a ladder of hints. Nothing opens unless a student asks for it, and no rung gives the answer away, so the help builds the method instead of replacing it.
Builds independence
A wrong answer that explains itself.
When an answer matches a known misconception, the feedback names it and explains the thinking behind it, rather than only marking it wrong. Here, subtracting the squares instead of adding them.
Builds insight
Bring strong foundations into high-stakes maths.
Over 3,100 practice exam papers across every state credential, with marks allocated and solutions after submission.
Builds exam readiness
The long view
A maths platform that grows with your child.
The habits that make early maths feel achievable are the same ones that make senior maths approachable. We support them at every stage.
Foundation to Year 2
Number sense and early confidence
Visual models, counting and early strategies, with maths as something that makes sense.
Years 3 to 6
Fluency and reasoning
Problem solving and the working habits that carry into high school. In New South Wales, this is also where Opportunity Class and Selective test practice sits.
Years 7 to 10
Core concepts and algebraic thinking
Connected skills across number, algebra, geometry, measurement and data.
Years 11 and 12
Course pathways and exam preparation
Deeper problem solving, in the streams your state actually offers.
New South Wales · Opportunity Class and Selective
Practice for the Opportunity Class and Selective High School tests.
For New South Wales families, PiGrids includes Mathematical Reasoning practice for both entry points: the Opportunity Class test in Year 4 and the Selective High School placement test in Year 6. Timed papers show where a child stands. The Skill Builder then teaches one question type at a time, with a visual model and a check, so the next paper goes better.
Year 4 into Year 5
Opportunity Class
Timed Mathematical Reasoning papers and Skill Builder units, from reading a question closely to using a table, a bar or a picture to solve it.
Year 6 into Year 7
Selective High School
Timed Mathematical Reasoning papers and Skill Builder units, from careful reading and checking to pacing the whole paper.
How a child uses it
Sit, review, then build the skill
Sit a paper, review every answer with the reasoning laid out, then open the Skill Builder unit for the question types that cost marks.
Included on every plan, and it stays open after the free trial. Independent practice written by PiGrids, not provided by or affiliated with the NSW Department of Education. A band is a practice guide, not a prediction of placement. These papers cover the Mathematical Reasoning section.
Specialised topics
The exam, taught by its question types.
Senior maths rewards pattern recognition. Alongside the year courses, PiGrids has twelve topic masterclasses that cut across year levels and teach the exam the way an examiner sets it: by archetype. Each one names the question form, how to recognise it, the steps, the marks it carries, the band-level insight and the pitfall that costs students most.

Senior maths
When senior exams matter, preparation has already begun.
Strong exam performance is not built in a few weeks. It grows from years of clear understanding, regular practice and the confidence to meet an unfamiliar problem. PiGrids builds those habits early, and gives older students structured course and exam preparation when they need it.
