I agree with Betty. I had a friend who taught third grade and she made her kids write their multiplication facts on a sheet of paper like Betty describes every single day first thing when they got to school. Then they could go on to other things. They learned them and they got faster with it and they see the pattern of it.
I absolutely hated flashcards and could not learn them that way. I have to see a pattern.
I wish I had a teacher who taught me that way.
