What it really means
If times-tables practice has become a nightly battle, take a breath: Mexico’s official 3rd-grade program (the SEP curriculum your child follows) doesn’t require reciting tables from memory. It asks for something better: that your child builds a multiplication repertoire — knowing how to reach any fact from the ones they already own — and solves multiplications up to three-digit results by breaking them into small steps.
It also asks them to understand multiplication and division as inverse operations: one builds groups, the other takes them apart. If this looks different from how math was taught where you grew up, that’s normal — the reasoning behind it is solid.
In real life, this is what they’ll use to figure out what 4 packs of stickers cost, split 24 sweets among cousins, or estimate whether their allowance covers the school store.
Explain it like this
Set out 3 rows of 4 crackers on the table. Ask: “how many?” Let them count. Then say: “that’s 3 × 4 — three rows of four.” Now turn the tray: “and now? Four rows of three.” Same total. They just discovered 3 × 4 = 4 × 3 — half the times tables just became free.
Then play it backwards: “I have 12 crackers and I want rows of 4 — how many rows?” That’s 12 ÷ 4 — and they just used multiplication to divide, exactly as they do in class.
For the hard facts, teach the bridge trick: don’t know 6 × 7? Go through what you do know: 6 × 5 is 30, plus 6 × 2 is 12… 42. That’s not cheating — it’s the official strategy.
Try it today: at dinner, ask them to set the table “by multiplying”: “there are 4 of us and each person needs 3 things (plate, cup, spoon). How many things will you bring in total?” When clearing up, the inverse: “there are 12 things and 4 people… how many did each person bring?” Two minutes, no whiteboard.
How your child lives this at Brighton
At Brighton, this objective isn’t drilled with worksheets: it’s worked through projects and real situations — from the market to the lab — where multiplying and dividing are tools for solving something kids actually care about, in a bicultural environment where they do it in English too. If you’d like to see what that classroom feels like, book a school visit.
