Poke Salad Annie Posted January 8, 2011 Share Posted January 8, 2011 I found this link today for some oral *algebra* problems and thought they may be similar to the Singapore-type challenging word problems. I like what I see so far. Any opinions? Quote Link to comment Share on other sites More sharing options...
Poke Salad Annie Posted January 9, 2011 Author Share Posted January 9, 2011 Anyone? Also wondering about going for the Hands on Equations set, maybe to use with this. Since the first pages of the text from my link show a balance scale to illustrate the problems, I could probably figure it out myself. Just thought the little pawns and things from Hands on Equations were cute though. Quote Link to comment Share on other sites More sharing options...
stripe Posted January 9, 2011 Share Posted January 9, 2011 (edited) Love the name of the book -- Intellectual Algebra! Quite a few of the early problems (p 16-31 in the download, p 7-22 in the text's numbering) seemed boringly easy to me, matters of halves and doubling. The later problems do not strike me as Singapore CWP ish because they rely explicitly on algebraic expression such as What is the square of 3x + 4 or whatever. And the method of solution that is given in the text is algebraic, whereas Singapore relies on bar diagrams and other ways of solving without using algebra. So I am not sure it is a good substitute for Singapore in this case. I'm sure you could find some interesting sources of problems. Maybe this?

Poke Salad Annie Posted January 9, 2011 Author Share Posted January 9, 2011 (edited) Thanks for the links. I'll print off a few pages today and chew on them. :) I am looking at pp. 32 and 33 right now (of the Tower text) . Here's an example of what I wonder to be Singapore-ish: #21-- "The sum of two numbers is fifty, and the greater is only ten less than four times the smaller. What are the numbers?" #24--"The sum of two numbers is sixty-seven, and the greater lacks five of being seven times the smaller. What are the numbers?" Editing to add... Maybe I haven't had enough coffee this morning, so I'm a bit slow on the uptake. Edited January 9, 2011 by Poke Salad Annie Quote Link to comment Share on other sites More sharing options...
EKS Posted January 9, 2011 Share Posted January 9, 2011 Did you see that they are meant to be done orally, with no visual aids, including all of the algebraic steps to solve them, as the program was originally developed for the blind? I think the intention of the book is different, and this may be why so many of the problems seem easy and obvious, because the students are working on the difficult task of holding everything in mind while orally delineating how the problem is solved. I wouldn't use it as a substitute for Singapore, but it sure is interesting. Thanks for sharing it! Quote Link to comment Share on other sites More sharing options...
Poke Salad Annie Posted January 9, 2011 Author Share Posted January 9, 2011 Yes, I did notice that. I thought it might be nice for setting up problems on the dry-erase and solving in sequential steps to further understanding. Just tossing something out there....

Poke Salad Annie Posted January 9, 2011 Author Share Posted January 9, 2011 The Edward Lee Thorndike texts are kind of interesting too here . There are three books, with this being the third. Quote Link to comment Share on other sites More sharing options...
