    When I began teaching middle school in 1981, I clearly remember the textbooks having lessons on the properties but I don’t believe they were presented with any reasoning. I feel for my students who have not been taught any number sense and they don’t understand how to decompose and recompose numbers to accomplish addition more easily. I am determined to find a way to squeeze in number talks even if it is only 2 or 3 times per week.
