Snowfall Posted August 31, 2010 Share Posted August 31, 2010 We're doing RS level B and MEP Yr. 1, so it's still early, but I hear a lot of people talking about all the mental math their kids are doing in Math Mammoth and Singapore Math. Is that something that will eventually happen with RS or MEP? Quote Link to comment Share on other sites More sharing options...
mystika1 Posted August 31, 2010 Share Posted August 31, 2010 Hi, You are using 2 very good math programs that promote mental math. If your child/children are progressing and enjoying math time then you are in great shape.:001_smile: HTH, Penny Quote Link to comment Share on other sites More sharing options...
Satori Posted August 31, 2010 Share Posted August 31, 2010 We're in RS B, lesson 27, and I think it does mental math already, and started back in Level A. My daughter was doing 80+10 in her head today not using paper or even the abacus. We've not gotten far yet in MEP, although I'm interested to know about that program too.

Snowfall Posted August 31, 2010 Author Share Posted August 31, 2010 Hmm. I never thought about that, since it seems so basic from a 31yo's perspective, but I guess you're right, Satori. That just seemed to me more like a math facts thing. If 8+1=9, then of course 80+10=90. I guess to a 6yo, though....lol. DD just did her 9 week test a couple weeks ago. She was really excited about it. :) Quote Link to comment Share on other sites More sharing options...
truebluexf Posted August 31, 2010 Share Posted August 31, 2010 RS B is FULL of mental math!!!! Hardly anything is ever done on paper. :) Quote Link to comment Share on other sites More sharing options...
Bayt ul-Hikmah Posted August 31, 2010 Share Posted August 31, 2010 We just did lesson 76 in RS B and ds was adding 85+44, 95+59, 67+29 etc all in his head. It's amazing, really. We're also doing MM, and so far there is *nothing* close to this. We're only halfway through 1A though, so that might have something to do with it. :tongue_smilie: I'm liking MM as an independent supplement (and ds loves the puzzles), but RightStart just keeps impressing me. Love it, love it. Quote Link to comment Share on other sites More sharing options...
Satori Posted August 31, 2010 Share Posted August 31, 2010 Oh my gosh, Kate, you made me realize what a slacker I was! We'd probably be on lesson 76 if I didn't slack off on math all the time. I am adamant to be more diligent in sticking to our math schedule starting next week after Labor Day, which I'm calling our first day of serious school! (Up to now we've been pretty relaxed.) We are doing 3 days of RS and 2 days of MM and MEP, but I should increase RS to 4 days a week just to catch up. Quote Link to comment Share on other sites More sharing options...
Bayt ul-Hikmah Posted August 31, 2010 Share Posted August 31, 2010 Oh, we've been slacking too lol! We're trying to get back on it. Currently I have RS scheduled for three days a week, but I may bump it up to four or five as well. All of a sudden, I'm seeing the program in a new light. I've always loved it, but when I see my ds doing this awesome mental math, I want to really commit to RS and dig in full time. Quote Link to comment Share on other sites More sharing options...
LaurainMD Posted August 31, 2010 Share Posted August 31, 2010 I am loving the intuitive sense for numbers that my DD is gaining from RS. We are only on lesson 17 or so in level A, and she is doing mental math all the time because she has a true number sense. Quote Link to comment Share on other sites More sharing options...
forty-two Posted August 31, 2010 Share Posted August 31, 2010 MEP has quite a bit of mental math if you use the lesson plans - my impression is that a good 50% of the lessons start with a brief mental math section (at least, once you get going). Y1, Lesson 52, for example, has both simple mental addition and a deceptively simple complete-the-sequence activity, which requires not just mental addition/subtraction, but using those skills to find patterns. Really, a good chunk of Y1 qualifies as "mental math", since quite a few problems are meant to be solved without writing anything or using any manipulatives - so I'd say they qualify as mental math by default ;).

Snowfall Posted September 1, 2010 Author Share Posted September 1, 2010 RS B is FULL of mental math!!!! Hardly anything is ever done on paper. :) We're only on lesson 30-something of RS and just started 1B of MEP, so I guess I'll just see when I get to it. I haven't really considered single digit addition mental math, but I guess it is if you aren't writing it down or using manipulatives. Of course, RS does encourage the use of the abacus for a lot so far, so that doesn't seem mental to me. Then again, DD prefers not to use the abacus anyway, so I guess she prefers doing it in her head. Quote Link to comment Share on other sites More sharing options...
Poke Salad Annie Posted September 1, 2010 Share Posted September 1, 2010 Don't forget CSMP. It's great for mental math too. We love it. Oops! Forgot to add that it's also free--just the cost of paper and ink for printing. Quote Link to comment Share on other sites More sharing options...
