What it really means
If your child came home saying “son las cuatro y cuarto,” here’s the context: Mexico’s official SEP 3rd-grade program asks kids to do two things that go hand in hand — read both analog and digital clocks, and compare and order the duration of everyday activities using the hour, the half hour, the quarter hour and minutes.
The digital clock practically reads itself; the real challenge is the analog one, because it hides two scales on a single face: the big numbers name the hour, but for minutes that same 3 means 15 and the 6 means 30. Decoding that is a leap of reasoning, not memorization. And behind it comes the valuable part: a feel for time — knowing whether something takes ten minutes or a whole hour.
Explain it like this
Introduce the hands as two characters with opposite personalities: the short one is slow and serious — its only job is naming the hour — while the long one is fast and counts minutes, jumping by fives at every number. Skip-counting by fives is a skill they already own, so this jump lands easily.
Then turn the clock into a pizza: the whole face is one hour. If the long hand travels half the pizza and reaches the 6, half an hour has passed; if it covers one slice out of four and reaches the 3, that’s a quarter of an hour. Suddenly “quarter past” and “half past” — and their Spanish cousins “y cuarto” and “y media” — stop being odd phrases: they’re slices.
For durations, play time bets: “which takes longer — your shower or one cartoon episode?” Estimate first, check with the clock, then order the day’s activities from shortest to longest.
Try it today: appoint them the family timekeeper. At bedtime, ask for the time on an analog clock and throw down the challenge: “lights out in a quarter of an hour… where will the long hand be?” Check together whether they nailed it.
How your child lives this at Brighton
At Brighton the clock isn’t a worksheet exercise: it’s part of classroom life, where kids manage the timing of their own routines and projects — and, being a bicultural school, your child learns to tell time in English too. If you’d like to see it in action, book a school visit.
