Be afraid — be very afraid — of your child’s math book warns Annie Keeghan, who worked in educational publishing for 20 years, in Open Salon.
There may be a reason you can’t figure out some of those math problems in your son or daughter’s math text and it might have nothing at all to do with you. That math homework you’re trying to help your child muddle through might include problems with no possible solution. It could be that key information or steps are missing, that the problem involves a concept your child hasn’t yet been introduced to, or that the math problem is structurally unsound for a host of other reasons.
After a series of mergers and buyouts, few educational publishers are left, she writes. Many are skimping on quality control to rush new books (especially math books) to market to beat the competition.
