Keep it fun, broaden their horizons so rather than just teach this is how you do x and how you do y, give them some examples of where they might expect to find x being used or where you might find y being used in real life so they having something relate to. Once you get past basic maths, a lot of it isn't instantly recognisable in the real world, partly because its behind closed office doors, so explain that some maths might be found in banking, some in mapping, some in hedge funds, physics, computer games, gambling, detective work etc etc. Dont force anything because no one can predict the future and if things dont work out in the future, you dont want them looking back at this time as lost opportunities to have done other things, even socialising or learning something else, even though I doubt the demand for maths skills will ever die out apart from maybe WW3 breaking out.
