Understand the Commutative Property of Multiplication in Word Problems
Arrays are great for multiplication, but what if a word problem doesn't ask for an array? Learn an effective strategy for visualizing multiplication word problems by using knowledge of arrays to draw diagrams. A brief review of how rows and columns create an array is followed by two examples of diagramming.

Human Coordinate Plane: An Array of Desks
Use a kinesthetic activity to elucidate ordered pairs and coordinate planes. Arrange desks in a square array and distribute to learners cards with ordered pairs based on the locations of their seats. By having various groups of learners stand up depending on what number they have in their ordered pair or the sum of their coordinates, they can develop a visceral understanding of x- and y-axes, lines, and visual representations of equations like x + y < 2.
