There are three sets of the two posters included. (There are mini versions seen on the above picture.) One set is black and white which may be printed as coloring sheets. One is beige and one is brown. The posters are superb memory aids for students who confuse letters b and d and letters p and q! Students use them to remember how to look at their hands while reading and writing in order to remind them which letter is which. The left hand is b and the right hand is d. Flip your hands over and they become p and q.
