I use RS B for my 5yo math-loving son. I am also using the math games kit to supplement ps for my 3rd grade daughter who is more math resistant. My daughter came home last week with a table of mult and div facts up to 12x12 with instructions that we should practice facts at least 10 min a day using flashcards, games, etc. We have played a bit of Who's on top and Who's On Top Now but it is very frustrating for my daughter once we leave the 1s, 2s, 5s or 10s. We are *just* getting comfortable with the 3s. Is there a sequence to mastering the facts that is recommended that makes sense? Should we just progress in order - 4s, 6s, 7s, 8s, 9s? Is there a sequence to the games that would be less frustrating to my daughter? Any suggestions? Unfortunately we really can not hs math with her, so we can only supplement the ps system.
Thanks!

Oh - one last question. My son is about 3/4th of the way through B. Will I face problems later in C or beyond if ds has already mastered his mult facts through playing games with his sister?

If you look at the table of contents for books C and D, you'll see the sequence that they introduce the multiplication facts. I'm thinking the product memory game would be helpful at this point - your son could play it LOOKING at his envelope longer than your daughter would, and they'd get the facts in that way as an introduction. I think product memory is the first multiplication game to be used...

Hi Jenny, The advice given in the post following yours is good advice. I'd also like to add that once your daughter knows the 1's, 2's, 3's and 5's she can figure out the other multiplication facts by doubling the facts or doubling and adding depending on what fact she needs to know. An example is....when asked what is 8 x 6. If she does not know that but knows 3 x 8 =24 then 6 x 8 is double 24 which is 48. I would encourage you to continue playing the multiplication games going from the first games and moving along in the multiplication section. Do go back and play the multiplication memory game. That is one of the most popular games and allows her to "see" the skip counting patterns of two multiplication facts at once.

I hope this helps. Do feel free to email, post or call with any other questions you might have as well as continue this conversation.

Sincerely, Rosine

I have a piggy back question regarding multiplication. I can move this out to a new thread if needed. In C when you flash the abacus w/ for ex: 7x5. We've been discussing seeing it as 5x5+2x5=25+10=35. should he be doing 7+7+7+7+7?

thanks,
