A flash card is a small data storage device that uses a flash memory chip to store data. Flash cards can be quite small in size, with a capacity of many gigabytes of storage. The memory in these cards is non-volatile, so it does not require a power source to remain intact.
As your children progress, the flash cards teach them how to spell and form words, often with the aid of images and pictures related to the words. Other flash cards teach basic math skills, beginning with number identification and moving on to simple addition and subtraction.
