A firm favourite with our kids is the colour match game. We gathered a load of paint cards from a large DIY superstore, you know the little bits of card which show the range of colours and shades available. Just make sure you pick up two of each card. So I got 2 blues, 2 reds, 2 greens etc.
Take one of each colour chart and put to one side. Then using a craft paper punch, or scissors, cut out a piece of colour chart from each shade and glue to a clothes peg. (The wooden ones are best as the colour stands out). Once you’ve done this for each shade and colour, the kids can match the colour on the peg to the colours on the cards.
