If you're getting a little tired of the same old games and you're handy with a digital camera - this activity is fun to do with your child! (If you don't have access to a camera, you can achieve the same results with magazine pictures or by drawing shapes, etc. on paper.)
Go around your house, with or without your child, and take close-up shots of different objects - make sure you have some of the same things in a group, such as two different candlesticks, two or three toy cars, some vegetables or apples.... you can then print out pictures 9 or 16 to a page and make them into little photo cards. You will need duplicate pages, so you have at least two copies of each picture.
