Use the words in the word sheet table to complete the following tasks:

Task 1

Working with a partner look at the sets of numbers below, which match the list above. Write the four words in your book. Decide which of them is the odd one out, circle the word and explain why it is the odd one out. Also, write a sentence or two to explain what the other three have in common.

Set A 2 13 3 14

Set B 4 15 6 31

Set C 8 27 31 9

Set D 22 10 25 13

Set E 1 12 14 23

Set F 30 11 29 33

Set G 14 20 32 25

Set H 31 20 8 29

Set I 23 28 17 6

Set J 5 16 19 22

Task 2

Now that you can see a pattern to the sets of words, can you add a word to each group but keep the same odd one out?

Task 3

Now try to put your own group(s) of words with an odd one out. Swop the words with your partner and see if you can work each others out. It is sensible to pick sets which have an obvious odd one out for this task.

Task 4

Now try to sort out all the words from the list on the wordsheet into 4 to 6 groups
