Quantity is a particular amount of something, expressed as a number. Quantity cards for young children can have pictures of small sets such as dots, finger patterns, or 5- or 10- frames. The ones we have available on our site use a variety of pictures or “suits,” since matching quantities such as fingers and dots can help develop ideas about equivalence. Experience recognizing how amounts that look different can be equivalent helps children abstract, for instance, the “four-ness” of four when playing card games.
1-10 in Four Suits
These quantity cards use different sets for the quantities 1-10, starting with a traditional dot arrangement and then also using lines, ten-frames, and hands. Using these for games and activities emphasizes subitizing, the ability to tell the number of objects in a set quickly, without counting.
