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. -- Sincerely, Edward B.
