To clarify the bad description they are on 5.5 x 7.5 cards. The deck contains all the letters and numbers from 1 to 10. The numbers have pictures to indicate how many. For example, 3 has the number 3 along with 3 dogs. It does NOT have the word "three" printed on it, along with a number and a picture. The back is blank. I use them for online teaching and they work very well for that purpose.
