'morning all, Nancy referred to the teaching of multiplication and division as a concurrent action on her part. This is an excellent practice. When faced with introducing the operations to young children I have tried to link the four operations. I've often referred to this practice as "mucking" around with numbers. My practice has been to make up a grid (I'll try to represent it here but I may not succeed): _________ 7 5 From this grid of the array I can produce the   following relationships:  35  7 x 5 = 35   5 X 7 = 35 2 12 35 / 7 = 5 _________ 35 / 5 = 7 7 + 5 = 12 5 + 7 = 12 12  7 = 5 12  5 = 7 7  2 = 7 7  5 = 2 2 + 5 = 7 5 + 2 = 7 One can add 1/7 of 35 = 5; and 1/5 of 35 = 7. Note: I hope the array appears ordered on your monitor. It looks O.K. on mine) I know that the above is simply basic number facts but I did extend it into working with the four operations.
