I posted this on the general curric board but thought I'd try here, too:
So I'm all set to order NEM 1 for next year for my son, who will complete Singapore 6B this year in 4th grade, when I read Rainbow Resources' description of the program, particularly this:
Saxon's Algebra 2 ... covers a wider variety of topics, including polar coordinates, imaginary and complex numbers, and logarithms...Also, NEM is extremely weak in coordinate graphing. The slope-intercept method of graphing lines also is not covered...(etc.)
My question: is this a concern right now, or will the subjects be covered in due time? Also, I plan to use Key to Algebra with said son as a supplement; will that fill in the gaps?
And as a tagalong question -- have any of you Singapore Primary users supplemented for topics such as statistics and probability? Did you cobble together your own unit or use a specific book?
Thanks,
Karen
