Find out how good your sensory perception is by finding the pair of blocks that weigh the same.
Place the 12 blocks face down on the table and choose one and feel its weight. Now try to find it's twin with an identical weight. All pairs are colour coded so you can check to see if you are right. Loads of fun that encourages sensitive perception skills.
