Whilst children get used to counting on in tens and hundreds, sometimes it can be useful to count on in 25s and 50s, especially when using money or measurement. This is the second page published on counting in 25s and 50s, concentrating on money and is probably most suited to year 4 children.
This page can also be used to check that children use the correct method of writing money – some are very keen on adding a p, making £6.90 become £6.90p, which of course is incorrect.
