Review of Susan Greenwald’s book, Two Plus Two is Not Five

As a sixth grade math teacher, I absolutely agree with her statement that “children tend to struggle with higher-level math when they have not yet memorized the math facts.” Her declaration that “children should memorize the math facts” is a phrase I have repeated at parent conferences over and over, year after year. Susan Greenwald’s book may be an answer for many teachers. Not because it is more drill and practice, but because it teaches kids tricks and strategies for memorizing. I applaud her for producing such a book.
