Here’s my post (02/06/2025 22:24 - bottom of page 1) from a similar thread about learning the multiplication tables:

Basically, if you consider that of the table is a repeat of the first half (AxB=BxA) and get the easy ones out of the way first, it makes it a lot less daunting.
Do one set of numbers at a time so you can take advantage of the patterns/tricks (explained in the links - including 6s and 9s).
Then it comes down to practice. I highly recommend practicing with screens. Pick any multiplication game that you think will appeal to your child and turn them loose. Games not only provide instant feedback, they motivate the child to practice more rathe than it being a chore to practice at all.
Other posters offered different approaches, so I encourage you to look at the other posts in the thread.
As for division, once he knows his times tables and knows that division is the inverse of multiplication (if AxB=C, then C/A=B and C/B=A), he should be able to apply that knowledge for simple division problems. Long division is more complicated and he’ll have to learn that procedure separately.
