A Word About the
Different Editions
of Singapore Math

The Singapore Math U.S. edition consists of a textbook and workbook A and B for each grade, and a choice of a teacher's guide or a home instructor's guide or a simple answer key. Some of the popular supplementary books are sequenced according to the US edition (see below).

The Standards edition also consists of a textbook and workbook A and B for each grade. It currently has only teacher's guides, but home instructor's guides are in the works.

It is based on the US edition, but is newer, has a few added topics, and moves a little faster than the US edition by grades 4-5. It only goes to grade 5. A middle school series to follow the Standards edition is being planned. Until then, you can follow it with the US edition 6A and 6B (there is a bit of overlap)

The Standards edition has been approved by both the California and Oregon boards of education for use to meet those states' standards.

Christian Book Distributors currently is carrying the US Edition.

Reviews from THC Readers:

Suzanne from (Arizona, US) says:
I have purchased the Vroom and the Rainbow and find that they are the best CD's for children to understand math concepts. I have dozens of programs on CD's and I find that these are the best on the market.

It has been a while since I used them. The children love the programs as they are animated and entertaining while at the same time teaching or reinforcing a given skill. Each skill has a teaching component, two levels of practice and a challenge level. The kids can move up the levels as they progress.

Using this software I was able to advance the level of math with one of the children I was working with as she was very bright and able to grasp the step by step learning in a very concrete format. This child was only in kindergarten but was able to understand equivalent fractions introduced in the Vroom CD.

Because it was very visual and repetitive and introduced a new concept at a lower level and moved up little by little, she was able to grasp a mental concept that was challenging to teach an older child.
