The exercise I ran with these tiles was taking a random selection of 15-20 tiles, including negatives and asked the pupil to match the numbers to the word. Once they had completed that, I asked them to put them in ascending order. Using the negative numbers is a great way to help them understand that even though the number appears to be getting bigger, it's actually decreasing as it goes further left on a number line. To help with writing numbers in numeral, I took 5 number tiles and asked the pupil to write them all as a word and shown them different ways of writing it i.e. 77 can be written as seventy-seven or seven tens and seven ones - this strengthens their knowledge on place value. Also encourage their range of vocabulary such as ascending, descending, smallest, biggest, etc
There is lots that you can do with these tiles!
