[edit]Default multiplication tables in schools worldwide
[edit]According to multiplication table, in the English-speaking world schools use 1-12 multiplication tables, or 1-9. Can this maybe be distinguished between countries? In German-speaking Europe, schools use 1-10 by default. For sure in many countries they start with 0. What's the situation in different countries worldwide? --KnightMove (talk) 08:37, 24 October 2024 (UTC)
- Wait, why would one start a multiplication table with zero? Remsense ‥ 论 08:43, 24 October 2024 (UTC)
- I guess so that every possible product of two digits is included. Double sharp (talk) 09:36, 24 October 2024 (UTC)
- Why would one start multiplication tables with 1? We started with 2. Shantavira|feed me 09:00, 24 October 2024 (UTC)

- The curriculum in the UK is devolved.
- The English curriculum includes multiplication tables up to 12 × 12 (no word on whether 0 or 1 are included as tables, but multiplying by 0 or 1 is included).
- Wales (at least partly English speaking), only has up to 10x10
- Scotland goes up to 12.
- Northern Ireland doesn't explicitly have multiplication tables, but does cover "multiplication facts up to 10 x 10".
- My understanding is that education is a state matter in the USA so maybe there are 50 different curricula?

- US states generally delegate to school districts, so each county or township has its own standards (and then there are tons of non-public schools). But there are a few standard curricula or textbooks that many of them use, and regardless of approach many follow the same or similar broad standards. And finally, it's sometimes just a semantic difference whether it's called part of the "table" or just a loose fact. Some relevant articles:
- Mathematics education in the United States
- Common Core (3.OA.C.7 specifies "By the end of Grade 3, know from memory all products of two one-digit numbers.")
- Singapore math (popular in some parts of the US)

- It's been a long time since I was at school but I dimly remember the multiplication tables in the booklet went up to 13x13 though we only had to learn up to 12x12. NadVolum (talk) 12:40, 24 October 2024 (UTC)
- The 12 times table had a greater significance in my primary school days, since there were 12 pence in a shilling in those days. Alansplodge (talk) 14:10, 24 October 2024 (UTC)
- Ditto. Learning the 13 and 17 times tables might be of some value; the others can be trivially derived mentally by doubling (e.g. 9x14 = (9x7)x2) and similar expedients, or for nx19 ((nx10)x2)-n. {The poster formerly known as 87.81.230.195} 94.6.86.81 (talk) 12:44, 27 October 2024 (UTC)

- hm, Schoolhouse Rock (which has a fan wiki!) covered 2–9, 11, 12, plus zero (powers of ten). —Tamfang (talk) 21:40, 4 November 2024 (UTC)
