Learning mathematics is much more than memorization. Rote drill and practice have not shown to lead to significant improvements in mathematics abilities, but rather, using strategies that engage and strengthen the connections to different areas of the brain assists students in learning mathematics.
According to findings published in Teaching Children Mathematics, most students actually use a strategy to recall a fact. They are considered fluent if they can recall a fact within three seconds, which is a long time to be able to employ a strategy. For example, looking at the problem 19 + 6, students might move one from the 6 to make an easier, equivalent statement of 20 + 5.
