Educators take a moment a check out Timez Attack. It is an impressive new video game exclusively for learning multiplication tables. It's as high-tech and entertaining as a top video game, yet as rigorous and effective as one-on-one training with a skilled teacher. I’m a teacher of students with learning disabilities and emotional impairments who love playing video games, yet NEED basic math facts instruction. This works for them! School budgets are tight. However, do at least review this educational game as a possibility for future purchase. There is a free version available…check it out! There is one huge downfall…presently this program only runs on PCs, not MACs.
