Switching math programs (Singapore to Horizons)?

[Sue G in PA]

Temporarily. :) My 3rd grader has used Singapore through 2B. We love Singapore here. I was able to get a copy of Horizons 3 Books 1 and 2 at a yard sale for pennies. Just glancing through, it looks like it covers much of what Singapore 3A/B would cover...and some. Horizons is much more "standardized" than SM US Ed. (from the looks of it anyway). Would it be detrimental to my son to use these books next year and then go back to Singapore? It wouldn't be THAT much of an expense to just buy the SM workbooks (we already have the TBs) but we ARE trying to cut costs wherever we can. Thanks!

Horizons looks more standardized, doesn't it ?

I personally never switch 100% to Horizons. I use it in its entirety starting book 4 this year (well, almost entirety) but I use Math Mammoth conceptual worksheet when needed. Plus I add more in-depth problems from Math mammoth. It's v. easy to add some MM to Horizons. But I use Horizons as a spine since kiddos do better with spiral.

 

One thing I notice iwith Horizons is its severe lack of mental math and tricks. So you may want to do something to prevent your kids losing their ability to do mental math. E.g. iinstead of doing 45+71 in column, cross the problem and re-write it horizontally.

I did notice the lack of mental math and word problems. I could add in some of Singapores CWP. Perhaps I'll just ditch Horizons and go back to Singapore. :tongue_smilie: Trying to save a few pennies isn't always the way to go, lol.

I use Horizons math and think it is a great program.

I add Singapore's CWP and Mental Math workbooks as supplements, and I am very happy with this combination.
