Math Facts Practice

My students LOVE to go to the "Math Facts" center and use The Teacher Wife's math fact strips to practice their facts.  They take turns being in charge of starting the one-minute timer and try to be the first group to practice all nine of the fact in one rotation. They've never made it yet but its really good practice for them.  Next time we're going to start with the nines and move towards the ones so I make sure they get practice with those nines that seem to cause so much trouble!
