Look at Part 1. What are the missing numbers in equations A, B, and C?
A: 56
B: 5
C: 9
What related division equations could you write for A?
56
What related division equations could you write for B?
20
What related division equations could you write for C?
54
Look at Part 2. How many unit tiles would cover this rectangle?
27 unit tiles.
What multiplication equation represents the area of this figure?
3
What division equation could be used to find the unknown side length?
27
Why does multiplying the length times the width give us the same area as counting the tiles?
In an array, multiplying the number of rows by the number in each row gives the total number. A tiled rectangle is like an array. The width tells the number of rows and the length tells the number in each row.
