Due for replacement are the “Everyday Math” books. The board should also junk the middle schools’ “Connected Math Project” books. These are the ones my son, who was educated entirely in Seattle, remembers as those pretty little workbooks that just about killed his interest in math.
In a few days he graduates with a university degree in applied mathematics. I condemn the “discovery math” on his authority. In “discovery math,” students are expected to discover concepts and mathematical algorithms, often in groups. Then they write little essays on how they reached their answers.
It is also called “fuzzy math” because it often wants an estimate rather than the right answer.
It downplays paper-and-pencil work, letting the students use calculators.
