Bridges students learn more than one way to solve multi-digit multiplication expressions. This enables them to select the strategy that is most efficient for any given problem. In addition to the standard algorithm that many of us were taught, fifth graders also investigate: Area model & four partial products Doubling & halving Ratio table Using quarters Over strategy While my students use the new...

The array model, used throughout Bridges, is the subject of “Arrays, Multiplication and Division” by Jennie Pennant from nrich.maths.org. The piece outlines how the array model supports development of a sense of multiplicative relationships and describes how to move students from building multiplication facts and tables to exploring division as the inverse operation of multiplication.
