Should Texas' State Board of Education have rubberstamped McGraw's 3rd grade *Everyday Math* because the state textbook review panel okayed it?
State review panels do not always get it right. That panel was supposed to find factual errors, yet it missed 89 of them in **MACMILLAN'S 3rd GRADE TEXAS MATHEMATICS**
in this submission – by far the worst editing we have seen in 22 Math programs over three Texas adoptions. Here are samples.

After we filed our list, Macmillan admitted them in writing to the Texas Education Agency (we have documentation) and promised corrections in
its final 3rd grade Texas edition. But just as many factual errors may still remain uncorrected in other grade levels of this program that we
lacked time to check. For identification purposes outside Texas, where it would not be * Texas Mathematics*, its authors are Altieri, Balka, Day, Gonsalves, Grace, Krulik, et al.
