Most of my students need to work on mastering their multiplication facts. Mastering, and or memorizing is pretty difficult, so I work with them on at least knowing how to solve multiplication facts even though they don't have the answers memorized. I use a mixture of ways to teach it multiplication. I use touch math, which starts with repeated addition and skip counting which is the foundation of mastering the math facts.
Another strategy is using Super Speed Math from Whole Brain Teaching. They pair up with each other and practice their math facts with a partner, and the other person has the answers and checks as they go along. We also play math war, where they have to solve multiplication problems (using times tables), and whoever gets the highest answer gets all the cards.
Hope everyone has a great school year!! Enjoy the rest of your weekend.
