Your answer should be a number. Please explain your strategy.  I suggest using a coding system (letters/numbers) to represent the different items.
Remember to include your first name, last initial and teacher's name.

48
I figured out by starting out with two eyes and one mouth it could have two faces. Then I added another mouth, and another, and that gave me six faces. Then I got one nose and then I got one more that gave me twelve faces. Then I added one wig and I got twelve faces. I added one more hair and that got me 24 faces. Then I added one more wig and that got me 36 faces. Then I added the last wig and I got 48 faces.

4 wigs X 2 noses x 3 mouths x 2 eyes = 48 potato heads

I wrote on a piece of paper to get the answer and I think the answer is 48. I wrote how many faces the first wig had. The first wig had 12 faces so I counted by 12's 4 times to get the answer (because 4 is the number of wigs).

There were 4 wigs and 2 noses. So there are 8 pairs of wigs and noses. I found it by taking 4 X 2 = 8. Then there are 3 mouths. So there are 24 groups of mouths, noses and wigs. I found this out by multiplying 8 times 3. There are 2 eyes. So 24 times 2 is 48. So there are 48 heads you can make.
