The common-core math standards require that students learn the standard algorithm for multi-digit adding and subtracting—you know, the process in which you line the numbers up vertically to add ...

The second email came from a teacher in another state: I am teaching the traditional algorithm this year ... So just what are the Common Core Standards for math? They are a set of guidelines ...

(Erickson says the standard algorithm is derogatorily called the "granny method," but if so, that term is not widely used in math education or textbooks.) But it also requires them to understand ...

The following are three examples of calculation strategies students might discover on their own if they were taught standard algorithms first and allowed ... more time on these strategies than on ...

The goal of mathematics education is clear ... as opposed to the plug and chug of simple rules and algorithms. And nothing in the new standards will change this sorry state of affairs.

And, yes, they do learn concepts with a hands-on approach that is soon followed by a solid grounding in the standard algorithm. From Mary-Adele Allison: Children should have learned to draw math ...
