Just one idea: you don't come across things in multiples of 7 that often.
UK: eggs come in 6s. Pizzas get cut into 4s and perhaps 8s for a really huge one, so multiples of those numbers get seen around. Half is sort of easy (all my adult students can usually find half of a figure, especially if I encourage them to think of paying it out in money with £10 notes and £1 coins). 5 fits into the decimal system nicely. Threes are easy to count up.

- keithpeter 11y agoYou got me there! But just thinking around weeks, apart from a fortnight do you actually count the days in multiples of 7 or just think about months or a period of weeks?
- songshu 11y agoI became good at sevens working in a pharmacy store room in a large hospital where we did continue to count in weeks. Boxes of 112 were common. Inside you would find blister packs arranged in rows of seven with the days of the week printed.

- GurnB 11y agoThis is why I never had problems with multiples of 7. 8's on the otherhand can still give me pause...
