Percentages
What it means: working with parts out of 100, discounts, increases and proportions.
Common mistake: using the wrong whole.
Example: 20% of 45 is one fifth of 45, which is 9.

LANTITE Numeracy topics to revise
When revision feels too broad, split Numeracy into repeatable topics. Practise each skill separately, then use mixed questions when the method feels more familiar.
Fractions and decimals
What it means: comparing parts, converting forms and finding fractions of quantities.
Common mistake: treating the numerator and denominator as separate whole numbers.
Example: 3/4 of 28 is 21 because 28 / 4 = 7 and 3 x 7 = 21.
Ratios and rates
What it means: comparing quantities or calculating per-unit values.
Common mistake: confusing ratio parts with the total.
Example: In a 2:3 ratio, there are 5 parts in total.
Measurement and conversions
What it means: converting and calculating with metres, kilometres, grams, kilograms, time and area.
Common mistake: calculating before units match.
Example: 1.8 km is 1,800 m.
Data and graphs
What it means: reading values, scales, labels and totals from visual information.
Common mistake: ignoring the scale or axis labels.
Example: A bar reaching 6 grid lines on a scale of 5 shows 30.
Tables
What it means: locating the right row and column before calculating.
Common mistake: adding a total row twice or using the wrong category.
Example: If three groups have 18, 22 and 20 students, the total is 60.
Averages
What it means: finding a mean by adding values and dividing by the number of values.
Common mistake: dividing by the total instead of the number of items.
Example: Scores of 5, 7 and 9 have a mean of 7.
Money and financial numeracy
What it means: costs, totals, discounts, budgets and unit prices.
Common mistake: missing whether the question asks for one item or the total.
Example: 15 books at $8 each cost $120.
Probability basics
What it means: favourable outcomes compared with total possible outcomes.
Common mistake: using only the favourable outcomes as the denominator.
Example: 4 green counters out of 10 is 4/10, or 2/5.
Classroom numeracy contexts
What it means: applying maths to class groups, resources, attendance, surveys or excursion costs.
Common mistake: getting distracted by the story and missing the simple operation.
Example: 6 groups of 5 students means 30 students.
