Quantity Cards for Subitizing

Quantity Cards for Subitizing
subitizing cards

Quantity is a particular amount of something, expressed as a number. Our playing cards represent numbers, not with written numerals, but with visual models of the quantities. Children can see how many with these subitizing cards.

Subitizing is the ability to instantly recognize small quantities, without counting. The first stage of subitizing is perceptual subitizing. We see a small set such as 3 fingers simultaneously and “just know” that it is three. This ability is innate to human cognition and does not require learning other mathematical processes such as counting. The second stage of subitizing is conceptual subitizing when we see small quantities within larger quantities and use number relationships to perceive the whole. For example, 7 on a ten frame can be seen as five and two simultaneously. The whole is instantly recognized as a composite of its parts.

Our subitizing cards for young children use the visual models of traditional dots, but also include finger patterns, lines, and 5- or 10- frames. There are 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.

Las cartas de cantidad

La cantidad es un monto especifico de algo, y la expresamos usando un número. Para los niños pequeños, las cartas de cantidad pueden tener dibujos de pequeños conjuntos como puntos, patrones de dedos o marcos de 5 o 10. Las que tenemos disponibles en nuestro sitio web utilizan una variedad de imágenes o “palos”, ya que emparejar cantidades como dedos y puntos puede ayudar a desarrollar conceptos de equivalencia. La práctica de reconocer que cantidades que se ven diferentes pueden ser equivalentes ayuda a los niños a abstraer el atributo de cantidad. Por ejemplo, cuatro dedos y cuatro puntitos son muy diferentes de muchas maneras, pero son equivalentes en a la cantidad. Estas cartas se pueden utilizar para jugar muchos juegos de cartas.
