Ages 9–12 · Grades 3–6
Primary Maths (Ages 9–12)
Between nine and twelve, learners move from counting to genuine number sense. Fractions, decimals and percentages become connected ideas, multiplication facts become automatic, and geometry moves from naming shapes to measuring them.
These lessons build the foundations that make secondary maths feel manageable. Each includes a worked example to follow and a real-world context to talk about.
By the end of this stage
- Recall multiplication facts up to 12 × 12 quickly and use them to divide
- Convert confidently between fractions, decimals and percentages
- Identify prime numbers, factors and multiples
- Measure and calculate angles, perimeters and areas
- Find the mean, median and mode of a small data set and draw a suitable chart
