Fast Facts Strategy

This post is mostly for parents....I was searching for a few games to post when I came across this strategy for practicing/memorizing addition and subtraction facts. It is a second grade objective to memorize the addition and subtraction facts to 18. Some of you use aaamath.com as well as other sites for practice. This seemed like a good method, too. By "ticks", I believe they mean tallies or some other type of mark that reminds you that they have repeated the fact fluently. Give it a try and let me know if it works for you.
