Only correct if you are using the mathematical number designation of “four-point-one.” If instead it is the computer version designation of “four-dot-one,” then it is perfectly acceptable; in that case, the “dot” simply denotes a separation between major and minor versions.
This is not, of course, to say that the entire curriculum itself is not a worthless pile of detritus…
nice once 😀
its a dot, not a comma.
Unfortunately, it is, and I’m rather surprised that the kid knows that much about math.
My brother is in 6th grade and they’re sorting fractions. FRACTIONS. I remember doing those in, oh, FOURTH GRADE, before my district adopted EM.
I number sections in base 11. Sorry for the confusion.
I write for a high school curriculum, and we had the same complaint. From teachers.
But seriously, what should it be instead of 4.10? 4-10 would just get complained about sooner (the lessons are in reverse order!) and 4J sounds bad (worse is the letter conversion of 4.16). Maybe we should have used Roman numerals.
