Your teacher will give you a set of cards. On each card, Figure A is the original and Figure B is a scaled copy.

1. Sort the cards based on their scale factors. Be prepared to explain your reasoning.

2. Examine cards 10 and 13 more closely. What do you notice about the shapes and sizes of the figures? What do you notice about the scale factors?

3. Examine cards 8 and 12 more closely. What do you notice about the figures? What do you notice about the scale factors?

Your teacher will give you one of the six pieces of a puzzle.

1. If you drew scaled copies of your puzzle pieces using a scale factor of , would they be larger or smaller than the original pieces? How do you know?
2. Create a scaled copy of each puzzle piece on a blank square with a scale factor of .
3. When everyone in your group is finished, put all 6 of the original puzzle pieces together like this:

   

   Next, put all 6 of your scaled copies together. Compare your scaled puzzle with the original puzzle. Which parts seem to be scaled correctly and which seem off? What might have caused those parts to be off?
4. Revise any of the scaled copies that may have been drawn incorrectly.
5. If you were to lose one of the pieces of the original puzzle, but still had the scaled copy, how could you recreate the lost piece?

1. What is the scale factor from the original triangle to its copy? Explain or show your reasoning.

   ​

   

2. The scale factor from the original trapezoid to its copy is 2. Draw the scaled copy.

   

3. The scale factor from the original figure to its copy is . Draw the original figure.
   

   

4. What is the scale factor from the original figure to the copy? Explain how you know.
   

   

   The first line segment starts at the top left of the grid, slants downward 2 squares and to the right one square; the second line segment begins where the first ends, slants upward 2 squares and to the right 1 square; the third line segment beins where the second ends, slants downward 4 squares and to the right 2 squares; the fourth line segment begins where the third ends, slants upward 4 squares and to the right 2 squares.

5. The scale factor from the original figure to its scaled copy is 3. Draw the scaled copy.
   

   

   A triangle with the horizontal side extended to the right and the vertical side extended upward creating a figure that resembles the number 4. The figure is labeled original. On the right, the position labeled copy is blank.
