To Drill or Not to Drill?

Should both practice and drill be used in the classroom or at home? It depends... what is the purpose for the strategy? If I want students to solidify a concept, process, etc. then I would have them practice the concepts in many differenct ways until they can demonstrate they understand the concept. So, in general, practice is the strategy to use to have your students "eat mangoes." However, drill does have a place in learning basic facts. Once students can demonstrate the concepts behind the 4 operations, it is important for them to obtain automaticity in their facts because if they don't have this automaticity, then later down the math highway they mostly likely will have car trouble. The car trouble is that those students without automaticity will have an additional cognitive task with any math that requires computation.
