My son was crying over math and just could not get the multiplication facts memorized. We tried xtra math to supplement and practice, and I even adjusted the timer to give him twice as much time, but he would freeze up under the pressure and it ended in tears. I stopped his regular curriculum and bought Multiplication and Division Facts that Stick. For a few weeks, we only did Multiplication Facts That Stick for math. He loved the games and we saw great progress. We eventually restarted his normal math, but kept doing Multiplication Facts that Stick, and then Divisions Facts that Stick alongside. It really got us over a hurdle, and without the crying and defeatism.
