Have you ever used the FREE website Math Magician?? In third grade, the students have to master multiplication and division by the end of the school year. This website helps them practice their facts quickly by timing them. They must answer 20 question correctly in under a minute.
I then created a chart for the students to use when they passed a level. They were able to add a sticker for each one (X1-X10). I had the same chart for division.
