When examining student samples of work in practice in multiplying whole numbers, what should teachers expect to find and then do to help the student?
What will be an ideal response?
Complete answers will include the following descriptions. The teacher may expect to find two error patterns. In error pattern 1, the student reuses the number regrouped (recorded about the tens column) when multiplying by ones. Ask the student to use the partial products algorithm and compare his or her answer with the original answer. In error pattern 2, the student adds the number regrouped (recorded above the tens column) before multiplying the digit in the tens column, rather than multiplying first and then adding on the number regrouped. Ask the student to use the partial products algorithm or build an array with base-ten blocks to solve the problem and then compare the answers to the original answer.
