Card walls
• “We don't learn to do arithmetic using a calculator. No, one starts with simple addition and by the time your ready to learn division it is done using pencil and paper (long division old school). Requiring the student to do the hard work of the long division process may help them to understand the conceptual division problem and the solution technique.”
