**Spark Your Learning**

On a road trip, Anna and her family stop at a ranch where bales of hay are being weighed. Describe the relationship between the two weights. How can you use the relationship to compare the weights?

Answer:

Given that,

The weights are 50lb and 500lb.

In 50lb the place value of 0 is one’s and the place value of 5 is tens.

In 500lb the place value from the write position is one’s, tens and hundred.

50lb < 500lb

or

500lb > 50lb

**Turn and Talk** What is another way to describe the relationship between the weights? How can you use that relationship to compare the weights?

1. Anna’s aunt opens a savings account for her. Anna, her brother, and her aunt all make contributions. The amount of each contribution is shown.

A. Complete the place-value chart to show the amount of money that each person contributes.

Answer:

The contribution of Anna’s aunt is 100 dollars.

The contribution of Ann’s brother is 10 dollars.

The contribution of Anna is 1 dollars.

B. What is the relationship between the amount of money Anna’s aunt contributes and the amount Anna’s brother contributes?

_______________________________

Answer:

Given that,

The amount of money Anna’s aunt contributes is 100 dollars.

The amount of money Anna’s brother contributes is 10 dollars.

Therefore the relationship between Ann’s aunt and Ann’s brother is 100 dollars > 10 dollars or 10 dollars < 100 dollars.

C. How does the position of the digit 2 change when the amount Anna’s brother contributes is multiplied by 10?

_______________________________

Answer:

Given that,

The amount of money Anna’s brother contributes is 10 dollars.

Therefore, the amount Anna’s brother contributes is multiplied by 10 is 10 x 10 = 100.

The digit 2 chances to the hundreds place.

D. What is the relationship between the amount Anna contributes and the amount Anna’s brother contributes?

_______________________________

Answer:

Given that,

The amount of money Anna’s contributes is 1 dollar

The amount of money Anna’s brother contributes is 10 dollars.

Therefore the relationship between Ann’s and Ann’s brother is 10 dollars > 1 dollars or 1 dollars < 10 dollars.

E. How does the position of the digit 2 change when finding ^ of the amount Anna’s brother contributes?
