Easy Memory Tricks for Maths Study

These are Pi Leo Academy’s suggested activities to adapt at home; names such as practice modes describe routines, not additional software features. They do not guarantee a score improvement.

Many students say the same thing before a test: “I understand it when I study, but I forget it later.”

That does not usually mean the student is careless or “bad at remembering”. It often means they are using a study method that feels busy, but does not help the brain bring information back when it matters.

The secret to memorising is not staring at notes for longer. It is practising how to recall them.

Whether your child is preparing for NAPLAN Maths, Selective Entry, a school test, or weekly homework, these simple memory tricks can make revision calmer and more effective.

1. Use the cover-and-recall method

Reading notes can feel familiar because the answer is visible. Assessments may ask students to recognise an answer, recall information or apply an idea. Trying to recall before checking can make gaps easier to notice.

Try this in 4 steps:

  1. Read one small section of notes.
  2. Cover the page.
  3. Say or write everything remembered.
  4. Check the notes and fill the gaps in a different colour.

This turns study into a mini test. That is a good thing. The more often students practise recalling information, the easier recall becomes in a real exam.

2. Break big topics into tiny chunks

A large topic can be easier to organise when it is divided into smaller parts. Instead of trying to revise “fractions”, students can split the topic into bite-sized chunks.

Equivalent fractions
Same value, different form.
Simplifying
Divide top and bottom by the same number.
Adding fractions
Use a common denominator first.
Fractions of amounts
Divide by the bottom, multiply by the top.

One chunk at a time feels less stressful. It also helps students see exactly which part they know and which part needs more practice.

3. Make a memory hook

A memory hook is a short phrase, picture, rhythm or rule that helps the brain grab the idea quickly.

Perimeter
Perimeter is the path around the outside.
Area
Area is the space inside the shape.
Mean average
Share the total equally.
Angles on a line
A straight line makes 180 degrees.

Students can try creating their own memory hooks and check whether they help. A silly phrase, a quick sketch, or a personal example can be much easier to remember than a polished definition from a textbook.

4. Teach it to someone else

Explaining an idea can reveal gaps, although a fluent explanation alone does not establish understanding. Check it with an example or a question.

A student does not need an audience. They can teach a parent, a sibling, a whiteboard, or even an empty chair.

Use this sentence starter:

“The trick is...”

For example: “The trick is to convert the mixed number into an improper fraction first, then multiply.”

This method is especially useful for Maths because students remember the process, not just the final answer.

5. Space the revision over several days

One long study session can feel productive, but memory fades quickly when revision is squeezed into one night. Short sessions spread across the week usually work better.

Day 1Learn the idea and try a few questions.
Day 2Cover the notes and recall the steps.
Day 4Try mixed questions without notes.
Day 7Do a quick timed review.

This is a quiet but powerful trick. Students remember more when they revisit ideas just as they are starting to forget them.

6. Keep a tiny mistake notebook

A mistake notebook can be short: one example, the missing step and a reminder to try later.

For each mistake, write:

  • What type of question was it?
  • What went wrong?
  • What is the correct trick or step?
  • One similar question to try again later.

Before a quiz or mock test, students can revise their mistake notebook instead of rereading everything. It is personal, targeted, and much less overwhelming.

7. Use pictures for abstract ideas

Many students remember Maths better when they can see it. A quick diagram can make an idea stick.

Fractions
Draw bars, circles or number lines.
Percentages
Use a 100-square grid or a money example.
Algebra
Use boxes for unknown values.
Geometry
Mark equal sides, right angles and missing lengths.

The drawing does not need to be beautiful. It only needs to help the student think clearly.

8. Finish with a two-minute brain dump

At the end of a study session, ask the student to close everything and write down the most important things they remember.

A good brain dump includes:

Key formulas, useful shortcuts, common mistakes, one solved example, and one question they still want to practise.

This gives the brain one final chance to organise the lesson before moving on.

A simple weekly memory routine

For busy families, keep it simple:

  • 10 minutes of cover-and-recall.
  • 10 minutes of one-question-at-a-time practice.
  • 5 minutes reviewing one mistake.
  • 2 minutes writing a brain dump.

That is less than half an hour, but it trains the exact skill students need in tests: remembering clearly, calmly and independently.

How Pi Leo Academy can help

Pi Leo Academy gives students structured practice for NAPLAN Maths and Selective Entry, with topic quizzes, one-question drills, mock exams and explanations that help students understand the steps behind each answer.

The best study habit is not memorising everything at once. It is building a rhythm where students practise, recall, review and try again.

Start small. Recall often. Review mistakes calmly. That is how memory becomes confidence.
