I use this log to go along with Ice Cream Math. I use for multiplication, but can be used with addition, subtraction, and division as well. You can use any type of marking to show that they mastered each number, and on the side of the number, you put how many times it took them to master that specific fact. We complete tasty facts daily, and on Fridays, they take a small quiz on the specific fact. If they pass the quiz, the following Friday, they move on; however, if they fail the quiz, which includes missing more than 2 facts, they have to re-take the quiz in a different format the following week.
