From mathematician extraordinaire Barry Garelick Ive been in contact with Jason Zimba who has read the series of articles I wrote at Heartlander and agrees essentially that standard algorithms should be taught in the early grades. He wrote this up as a blog post at McCallums blog. He says: The criticism that I referred to earlier comes from math educator Barry Garelick, who has written a series of blog posts that aims to sketch a picture of good, traditional pedagogy consistent with the Common Core. The concrete proposals in his series are a welcome addition to the conversation math educators are having about implementing the standards. Reading these posts led me to consider the following question: If the only computation algorithm we teach is the standard algorithm, then can we still say we are following the standards? Provided the standards as a whole are being met, I would say that the answer to this question is yes. He provides a table showing how he recommends meeting the standards for addition/subtraction for first grade. (See commoncoretools.me/…/TeachingASingleAlgorithm-2014-0…) It recommends teaching the STANDARD ALGORITHM for multidigit addition and subtraction.
