How to learn multiplication facts
Learn one table at a time.
Select one multiplication table to learn at a time. Start with the simple tables such as 2s , 10s , 5s, and 11s.
By the time you learn the more difficult tables such as the 7s and 8s, you will already know several facts. Remember , 1 x 4 is the same as 4 x 1 so you only have to learn half of the multiplication table because the other half is just written the other way.
