Learning to count and sort things is not just a basic math skill, but also plays into the development of language, visual skills, and logic & reasoning.  This fun set includes five different brightly-coloured cups and five matching "coins" in each colour (25 coins in all), as well as a drawstring cloth bag.  Use the bag to blindly pick out coins and then find a matching one; sort them into the same-colour cups; turn the cups over and use them for memory games; or create patterns of colour and challenge your child to complete the series.
