lots of little ducklings Posted January 23, 2014 Share Posted January 23, 2014 Lol. The family I used to tutor used abeka, but totally skipped this. I happily followed suit. Not sure any of us adults ever even figured out *how* to do it, and there were something like 8 graduate degrees between us all. :-) Quote Link to comment Share on other sites More sharing options...
kiana Posted January 23, 2014 Share Posted January 23, 2014 Yeah, I use it, but you really don't need it. If I were doing bookkeeping without a calculator you're darn straight I'd use it, but there's not a lot of need for that outside Amish communities and the like.

Joker Posted January 23, 2014 Share Posted January 23, 2014 We used it here and there for fun. Youngest dd really liked doing it. Quote Link to comment Share on other sites More sharing options...
klmama Posted January 24, 2014 Share Posted January 24, 2014 I thought Abeka was the only program that still used it. It's a fun trick, if you like that sort of thing. If not, skip it. Quote Link to comment Share on other sites More sharing options...
.... Posted January 24, 2014 Share Posted January 24, 2014 I think we encountered this in one of the Life of Fred books...Jellybeans or Kidneys, maybe?? I can't remember. Anyway, I had never heard of it, either. My son thought it was interesting. Quote Link to comment Share on other sites More sharing options...
AmericanMom Posted January 24, 2014 Share Posted January 24, 2014 My kids have had to use it in factoring. It's a quick way to see if 9 is a factor of a big number, along with the other tricks for other numbers, and I don't allow calculators until algebra 1, and then only for super messy numbers. There are lots of times a calculator is slower than mental math, in real world problem solving. Just my two cents, I know I am pretty old fashioned. But my father can solve most complicated math problems in his head faster than I can get out a calculator and plug in the numbers, and it keeps one's brain exercised as well. My dh is faster than my calculator too, though not quite as fast as my father. I didn't get quite that good an education in mental math, but I want that for my kids. He was in one of those tiny country schools a long time ago where they had to do compound interest problems in their heads and such. Amazing.
