The diagrams below represent piles of pennies.

1. Which pile has more pennies? Explain your reasoning.

   Hint (a):

   Try calculating the sum of each pile.

   Answer (a):

   Don't forget to state which pile has more!

   Pile #1 has $81$ pennies and Pile #2 has $80$ pennies.

2. Write two different numerical expressions to represent the number of pennies in each pile.

   Hint (b):

   What different ways can you calculate the sums of the piles?

   For instance: $\text{Pile #1} = (6)(12) + 6 + 3$

3. Write a number comparison statement(using $>$ , $<$ , or $=$ ) to show if the number of pennies in one pile is greater than the other or if they are the same.

   Hint (c):

   Remember:
   $>$ means that the number on the left is greater than the number on the right and $<$ means that the number on the left is less than the number on the right.
