## Common core and other absurdities

A professor at Cal of all places:

when teaching fractions, the teacher required that students draw pictures of everything: of 6 divided by 8, of 4 divided by 2/7, of 0.8 x 0.4, and so forth. In doing so, the teacher followed the instructions: “Interpret and compute quotients of fractions, and solve word problems involving division of fractions by fractions, e.g., by using visual fraction models and equations to represent the problem. For example, create a story context for 2/3 divided by 3/4 and use a visual fraction model to show the quotient.” Who would draw a picture to divide 2/3 by 3/4?

This requirement of visual models and creating stories is all over the Common Core. The students were constantly told to draw models to answer trivial questions, such as finding 20% of 80 or finding the time for a car to drive 10 miles if it drives 4 miles in 10 minutes, or finding the number of benches one can make from 48 feet of wood if each bench requires 6 feet.

A student who gives the correct answer right away (as one should) and doesn’t draw anything loses points.Here are some more examples of the Common Core’s convoluted and meaningless manipulations of simple concepts: “draw a series of tape diagrams to represent (12 divided by 3) x 3=12, or: rewrite (30 divided by 5) = 6 as a subtraction expression”…

the most astounding statement I have read is the claim that Common Core standards are “internationally benchmarked.” They are not. The Common Core fails any comparison with the standards of high-achieving countries, just as they fail compared to the old California standards. They are lower in the total scope of learned material, in the depth and rigor of the treatment of mathematical subjects, and in the delayed and often inconsistent and incoherent introductions of mathematical concepts and skills.

For California, the adoption of the Common Core standards represents a huge step backward which puts an end to its hard-won standing as having the top math standards in the nation. The Common Core standards will move the U.S. even closer to the bottom in international ranking.

We grew up in an unenlightened time when the nuns gave us all addition and subtraction speed tests in first grade, multiplication and division speed tests to follow shortly. If we had to do the things above, we might have reduced our math SAT score by 800 points or so. In another example of government insanity, Michael Barone laments the acceleration of the regulatory state when Moore’s Law, twitter, yelp and uber all point in precisely the opposite direction.
