Websites for Developing Math Fact Mastery

Written by Donna Boucher

Donna has been a teacher, math instructional coach, interventionist, and curriculum coordinator. A frequent speaker at state and national conferences, she shares her love for math with a worldwide audience through her website, Math Coach’s Corner. Donna is also the co-author of Guided Math Workshop.

Let’s be clear—students need to have automaticity with their basic facts. What’s changed is the way we teach facts, moving away from rote memorization toward a strategy-based approach. Students learn unknown facts by reasoning about facts they know. For example, a student might not automatically know 6 + 7. If they know, however, that 6 + 6 is 12 then they can reason that 6 + 7 must be 13, because 6 + 7 is just one more than 6 + 6. Moving students from reasoning to mastery takes practice. Today, I have two free websites for developing math fact mastery.

  • XtraMath This free website uses pretests to determine students’ needs and then tracks student progress and adjusts their practice.  Parents receive weekly emails showing their child’s progress. There is also a premium version with more features as well as mobile apps.websites for math fact mastery
  • Arcademic Skillbuilders  This free website uses highly engaging video arcade-type games that kids will want to play.  Many of the games have settings that let kids focus on certain facts.  This site is constantly adding new games, and they now offer both iPhone and Droid apps (for a small charge).

Both are great options for use in the classroom or to share with your parents!
