|a This paper reports on the answers indicated by research studies to nine questions concerning the teaching of multiplication and division. (1) Should multiplication facts be memorized? Answer: Yes, at an appropriate time. (2) How should multiplication be conceptualized? Answer: Normally addition of equal addends; sometimes arrays or Cartesian-product. (3) Is distributivity important? Answer: Yes, for comprehension, transfer and retention. (4) What other approaches work? Answer: Inductive. (5) What aids advanced work? Answer: Knowledge of multiplication properties. (6) How does the difficulty level change in division? Answer: No conclusion. (7) Which division algorithm should be used? Answer: No conclusion. (8) How should quotient digits be estimated? Answer: No conclusion. (9) How are measurement and partition situations associated with division? Answer: Subtractive algorithm with measurement, distributive with partition; partition problems generally more difficult. (RS)
