1-67.

The diagrams at right represent piles of pennies.

Which pile has more pennies?

**Explain**your reasoning.Try calculating the sum of each pile.

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

Don't forget to state which pile has more!

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

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

For instance: Pile #1 = (6)(12) + 6 + 3

Write a number

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