Easy way to differentiate `teen and `ty` numbers

Teen” n ty numbers can be very troublesome for some students who have learning difficulties because they do not realise that “teen” means 10, and the usual rule of saying tens before ones is broken. For example, sixteen means literally “six and ten”, which really should be “ten and six”. Also 11 and 12 break the “teen” pattern by not being “oneteen” and “twoteen”. Further confusion can occur for the students who fail to realise words ending in “ty” are tens. In particular, many students confuse “sixty” with “sixteen”. Persistence in teaching “teen” and “ty” is needed in overcoming these problems as understanding these numbers is essential by the time part-whole thinking emerges.
