Visit the National Library of Virtual Manipulative's Rectangle Multiplication applet. Review the Instructions for using the manipulative. After exploring the tool in the "Show Me" mode, try some on your own by selecting "Test Me." Compare the process used to represent a solution to a division problem (with a remainder) using this online array tool, with the procedure used with the "traditional algorithm" or pencil-and-paper method.
Work through several of the "Grade 6 Problems." What are some strategies you could use as a teacher to help the students analyze these more complex situations? Select two of the problems and explain how would you use the strategies for these problems.
