When we see things like this we should all send letters to the publisher trying to educate them to the proper use of SI. I just finished reviewing an elementary algebra book by Almy/Foes that was terrible. Basically no metric usage at all, and when metric units were used, they were just conversions.
Publishers need to hear from people that know the correct way to use SI, otherwise they will continue to stumble along using cc, KPH, and K (for kilometer).

Since the SI doesn't use mixed units like that, it is NOT an example of how SI is taught. It is an example of how metric is mistaught. The author and publisher should know better and not teach their ignorance to kids.

Hi all,
Yesterday I was browsing in Staples for three ring binders. I looked at math and reading workbooks for grades 1st- 6th. In math starting in 2nd grade SI units are introduced with USC. There are word problems such as a drive way is six meters long. A truck is 4meters and 62 centimeters and the car is 3 meters and 72 centimeters. Can both fit in the driveway? Grade 6th has geometery problems in using feet and yards in one problem and meters in another. This is a sample of how SI is taught along with conversion back and forth.
