Over on YouTube there is a video illustrating some of the problems with widely adopted curricula for arithmetic. The video “Math Education: An Inconvenient Truth” is presented by M. J. McDermott, who is a TV meterologist in Seattle (WA; US), and it skewers Everyday Mathematics and Investigations in Number, Data, and Space®.
The focus of the video, which is promoted by a Washington-based group named “Where’s the Math” and is aimed at informing parents, focuses on the teaching of algorithms (strategies of systems for solving problems) in arithmetic. Teaching problemsome algorithms is only one of the problems in faulty arithmetic (and other) curricula; other problems include inadequate demonstrations of the algorigthms, insufficient practice of them, weak choices of the examples used in teaching, and etc. Beyond the problems with algorithms, there are similar problems with teaching fundamental concepts, promoting numbersence, and on and on.
So, check the video. If you want, visit Where’s the Math’s Web site.
