I don't have a web source, but last yr when DD was in K and begged not to have to count anymore ducks and balls, really wanted to understand multiplication and division I picked up two books from "flash Kids" it took about 2 minutes of instruction on each book and away she went with it, very simple instruction and then about 12 problems per page, not overwhelming for a beginner. hope that helps...
here's a link to the muliplication book:
