How old is your dc? I started 1A with my dd when she was 5 and tried flash cards and found myself beating my head against a wall for 3 years (no kidding). But then she suddenly got it around the time she turned 7. Sure, the kids will naturally memorize up to sums of 5 and 6 but past that, I found some effort needs to be made so this is what I found in lieu of flash cards and seems to support the CM hands on discovery:

For written practice, I printed a circle mat, the Partner Sheets for familes up to 18, and Tile Card sheets on cardstock and laminated them (

The site has a lot of activities to practice those math fact families which supports discovery, drill, practice, and fact families. There are card games, tests, practice sheets, number finds, the works.
I promise you this beats flash cards any day of the week. Neurological Developmentalists will tell you to forget what you know about flash cards anyway because you are asking the child to output something they don't know yet - imagine taking a quiz you haven't been able to study for. *IF* you are going to use flashcards, can I plead with you to get the flashcards that show the problem AND the answer? Have the child read a SMALL stack of flash cards (maybe 5-10 facts tops) to you then start occassionally covering the answer to check for recall. If they don't know the answer immediately, say, "No big deal, nice try," show them the answer and move on. You want to start at 100% input (they read to you), slowly moveback to 75% input (you are "quizzing" every 4th card type of thing), and work your way back until they are able to give you 100% answer. The following week, have a review time of the previous week's facts and have time for this week's facts. They also sell trinagle shaped flash cards or you can print your own from

I hope this gives you some more enjoyable ideas than flash cards wthat will get you to the same goal. Good luck!!
