In what grade and how do students learn the multiplication tables?
The Investigations program formally introduces the concept of multiplication in the beginning of third grade in a unit called, Things That Come In Groups. In this unit, students begin work on factor pairs and multiples (with products up to 50). In fourth grade student work in two additional multiplication units, Arrays and Shares and Packages and Groups. In Arrays and Shares students finish their work with multiplication facts up to 12 X 12. You can find a more formal description of each multiplication/division unit at the Investigations website (grade 3 and grade 4): http://investigations.terc.edu/curr/curr0.
