In the first slide we see the numbers 1,6,3,2 and 5. All you have to do is find the smallest number, after you've done that you have to find the next smallest number, keep doing this until all the numbers are sorted.
In the second picture we see the introduction of money. The values are 60p, 20p, £1, 5p and 400p. This one is slightly trickier because of the symbols. The method is the same as the last question, although don't be put of by the fact that a pound is in there. The highest value is 400p evn though you might think £1 is the highest, £1 is reall 100p, so you can see which one is the smallest and which is the largest.
