A 4-week study plan for the NZ teacher numeracy requirement

Four weeks, one clear plan

The LNAAT numeracy requirement doesn’t have to feel overwhelming — it just needs a plan. Because the test is adaptive and covers a range of difficulty levels, the most effective preparation isn’t cramming the night before: it’s steady, topic-by-topic practice that builds your accuracy and confidence over time.

This four-week plan is designed for primary ITE applicants who have a few hours a week to spare. Adjust the pace to fit your schedule — what matters is consistency, not speed.

Before you start: know where you stand

Before Week 1, take the free SN Academy diagnostic. It takes about 15 minutes and gives you a clear picture of which numeracy topics are solid and which need the most work. Use that result to weight your time in the plan below — if fractions are a weak spot, spend longer there.

Week 1 — Number sense and place value

The foundation of everything in numeracy is a confident understanding of how numbers work. This week, focus on:

• Reading and writing whole numbers, decimals, and negative numbers
• Ordering and comparing numbers on a number line
• Rounding to whole numbers, tenths, and hundredths
• Understanding place value — what each digit in a number actually means

The LNAAT is pitched at NCEA Level 2 — a step above University Entrance — so don’t assume the basics are too easy to practise. Solid number sense makes every other topic faster.

Aim for: 3–4 short sessions of 30–45 minutes. Review any answers you got wrong before moving on.

Week 2 — Fractions, decimals, and percentages

This trio appears across the test in various forms: converting between them, calculating discounts, working out proportions. They’re interconnected, so learning them together helps.

• Converting fractions ↔ decimals ↔ percentages fluently
• Adding, subtracting, multiplying, and dividing fractions
• Percentage increases and decreases (e.g. a 15% pay rise, a 20% discount)
• Finding a fraction or percentage of a quantity

Real-world contexts matter here — the LNAAT uses scenarios you’d encounter as a teacher or in everyday life. Practise in context, not just as abstract sums.

Aim for: 3–4 sessions. If Week 2 feels hard, add an extra session before moving on — this topic carries a lot of weight.

Week 3 — Ratios, rates, and measurement

Ratios and rates often catch people off guard because they don’t look like “maths” until you’re staring at the question. This week:

• Simplifying ratios and sharing quantities in a given ratio
• Speed, distance, and time problems
• Unit conversions (km to m, kg to g, litres to mL)
• Perimeter, area, and volume of common shapes
• Reading scales, rulers, and measuring instruments

The LNAAT includes interactive items — you may be asked to click or drag to answer, rather than type or select. Keep that in mind as you practise: thinking through the process matters as much as getting the right number.

Aim for: 3–4 sessions, mixing topic practice with timed question sets.

Week 4 — Data, graphs, and consolidation

The final week covers data interpretation — a strand that rewards careful reading more than calculation — and brings everything together.

• Reading tables, bar charts, pie charts, and line graphs
• Calculating mean, median, mode, and range
• Interpreting probability statements
• Mixed practice sets across all Week 1–3 topics

By the end of Week 4 you should be revisiting your weakest topics (flagged in Week 1 and reinforced through the plan) and working through mixed sets at pace. The aim isn’t to rush — it’s to feel settled and ready.

A few things that make the difference

• Review wrong answers, don’t just count them. Understanding why you got something wrong is worth more than doing ten more questions correctly.
• Short sessions beat marathon study. Four 40-minute sessions across a week are more effective than a single 3-hour block.
• The test is adaptive. It adjusts to your level as you go, so there’s no fixed difficulty to “train for” — breadth and accuracy across topics is what prepares you best.
• Rest before the test. The day before, do a light review only. Sleep matters for cognitive performance far more than one more practice session.

The free diagnostic on SN Academy’s NZ hub is the best first step — it takes the guesswork out of where to focus, so you spend your four weeks on the right things.
