ABSTRACT
Jane spent many good hours and finally memorized the multiplication table when she was going to elementary school herself, and now she is teaching the same multiplication table to her own children. Search on Internet or in resource books and one will find this 13 by 13 multiplication table. She created some well-rhymed poems, made up some songs, talked to other teachers and found a way of "finger multiplication" for dealing with multiplying by 9. When children need a multiplication fact where the first factor is smaller than or equal to the second one, they can retrieve this information directly from the table. In doing multidigit multiplication problems, Jane's children often make the mistake of treating a 2-digit number as two separate, 1-digit numbers. Jane heard of a new method of multiplication, line multiplication, from Mr. Williams, the teacher in the room next door to hers.
