Finding 10 more or less

In maths this week we have been finding 10 more or less than a given number using a magic number finder.  The number finder can reveal the number that is 10 more or less  when we use it with a 100 square.  We have had great discussions about the patterns we can see in the 100 square using our knowledge of tens and units.
