Example, sort the numbers 8, 22, 18, 49 and 100 into the Carroll diagram: 1 Deal with one number at a time 2 For example: look at the number 8 3 Go through each of the criteria, in turns, to work out which box it should go in 4 Then cross off number 8 from the list 5 Next look at 22 and do the same, and so on P a g e 10 | 17 P a g e 11 | 17 56 P a g e 12 | 17 P a g e 13 | 17 1 Fill these numbers into the Carroll diagram, then add your own numbers 7, 16, 21, 12, 25, 150, 76, 34, 2, 129, 27, 66, 240 Odd Not odd Multiple of 3 Not a multiple of 3 2 Put the following numbers into the correct place: 54, 2, 19, 44, 24, 13, 4, 41, 16, 35, 36, 60 Multiple of 4 Not Multiples of 4 More than 30 Not more than 30 P a g e 14 | 17 3 Put the following numbers into the correct place: 21, 99, 28, 66, 81, 36, 29, 18, 32, 42, 52, 17, 34, 91 Multiples of 7 or 9 Not Multiples of 7 or 9 Less than 45 Not less than 45 4 Can you think of 4 numbers to go in each section? Not Multiples of 2 Multiples of 2 Multiples of 5 Not Multiples of 5 5 Can you draw two shapes to go in each section?
