1) Think about a square whose sides are twice the
length of the sides of the square on this grid.
Compare the areas of the two squares. How many
times greater is the area of the large square
compared to the small square?

1) This 4 by 4 square would become an 8 by 8
square if you double the length and the width.

1) This 4 by 4 square would become an 8 by 8
square if you double the length and the width.
5

• The 4 by 4 has an area of 16.
• The 8 by 8 has an area of 64.

6

• The area of the larger square is 4 times greater
  than the area of the smaller square.
• 4 x 4 16
• 8 x 8 64

X 4

1) The fact that the area is 4 times as great can
be seen by dividing the larger square into 4
smaller squares.

2) Draw a translation of the figure shown on the
graph. On your translation, label the vertices
and give the ordered pair for each vertex.
