Are your kids learning how to read or studying multiplication tables, historical events or foreign languages? Some memorization tasks don't lend themselves to meaningful mnemonics. For these, flash card exercises work well.

Now you can put a digital twist on the flash card system. Instead or index cards, use your computer. These programs will help you make digital flash cards. Best of all, you can't beat the price-free!

1. Granule
Granule organizes flash cards according to the Leitner system. As you quiz yourself, the cards you guess correctly are moved to the back of the lineup. The cards that stump you stay up front. You spend more time on the answers you have trouble memorizing.

Simply enter text for the fronts and backs of your digital cards. The program was designed for word memorization. In fact, it can pronounce words for you. However, this setup requires a separate sound dictionary. You can get details on the Granule Web site. You can put any text, including numbers, on the cards.

Granule includes everything it needs in one folder. No installation is required. To remove it, simply delete its folder.
