Young children love learning
They ask questions constantly: why, how, what happens if? That curiosity is exactly what maths needs.
But maths is also unforgiving about foundations. Research consistently shows that fluency early on predicts later success in secondary school. Miss number bonds to 20, and a year later 28 + 17 becomes a struggle, let alone fractions and long division. The gaps accumulate quietly until maths starts to feel like a wall.
