Find The Odd Thing

Read a group of four or five words, and ask your child to pick out the one that does not match with others and ask them why.
Below are few examples:

If you read "dog, cat, elephant, rose", then your child should say "Rose - not an animal".
If you read "lion, giraffe, cat, monkey", then your child should say "cat - not a zoo animal ".
If you read "carrot, potato, tomato, apple", then your child should say "apple - not a vegetable ".
