She has one particular student that quite does not understand how to multiply a three-digit number by a one digit number. She also has offered small group and one on one help to this student, but he still does not understand the concept of regrouping when multiplying. What are some ways that Mrs. Starks can get her student to understand multiplying a three-digit number by a one digit number? Solution: (Rates are posted for this solution!) Mrs. Starks could use a different strategy other than the standard algorithm. I also teach fourth grade. I teach my students several different strategies. Some of the strategies include break apart, lattice, window, and Japanese. These seem to really help my students. Mrs. Starks could research how to implement these strategies into her classroom and hopefully it would help the student.
