Explanation

Every object has a colour, a shape and a size. A ball is round, a book is rectangular, a watermelon is big, a cherry is small. Using these features we sort things into groups and find the odd one out.

Worked examples
Tomato, apple, strawberry — all red.
Circle, triangle, square, apple — the odd one is the apple: it is a fruit, not a shape.
Class activity

Children find 3 things of the same colour in the classroom and name them.

Practice
1
What colour is a fir tree in winter and summer?
2
Find the odd one by colour: lemon, banana, cucumber, chick
3
Which is bigger: an elephant or a mouse?
