Most parents notice trouble at Year 8 or 9. The Maths grades drop, the homework drags, the confidence wavers. The instinct is to hire a tutor and patch the gap.
By then, the gap is usually three or four years old.
Secondary Maths is built almost entirely on a small set of primary foundations: place value, fractions, ratio, proportion, multiplicative reasoning. If a child reaches Year 7 shaky on any of these, every new topic — algebra, geometry, statistics — is built on sand.
Years 3 to 6 are when these are taught — usually once, often quickly, rarely revisited:
A child who masters these in primary walks into secondary school relaxed. A child who hasn't quietly drowns for the next five years.
"By Year 8, the cost of fixing what should have been built early is enormous. By primary, the cost is just attention."
Primary schools teach to the curriculum, not to mastery. A topic gets covered in Year 4. The class moves on. Some children got it. Some didn't. The ones who didn't are now expected to apply it in Year 5.
There is no time and no class size that allows a teacher to stop and say: nobody moves until everyone can do this.
That is what mastery teaching is. It requires small cohorts and a teacher who refuses to leave anyone behind.
If your child is in Year 3, 4, 5, or 6 — this is the window. The foundations they build now will quietly decide whether secondary Maths feels easy or impossible.
If your child is younger, even better. Foundations laid early do not need patching later.
By Year 8, the cost of fixing what should have been built early is enormous — in tutoring fees, in lost confidence, in the years of school that already passed. By primary, the cost is just attention.
Pay it now.
