Big Ideas
● Area models are related to addition and multiplication.
● Area covers a certain amount of space using square units.
● When finding the area of a rectangle, the dimensions represent the factors in a multiplication problem.
● Multiplication can be used to find the area of rectangles with whole numbers.
● Area models of rectangles and squares are directly related to the commutative property of multiplication.
● Rearranging an area such as 24 sq. units based on its dimensions or factors does NOT change the amount of area being covered (Van de Walle, pg 234). Ex. A 3 x 8 is the same area as a 4 x 6, 2 x12, and a 1 x 24.
● A product can have more than two factors.
● Area in measurement is equivalent to the product in multiplication.
● Area models can be used as a strategy for solving multiplication problems.
● Some word problems may require two or more operations to find the solution.
