Answers: Using Estimation to Make Math Easier!

Yesterday, Ms. Hoffman asked for your help. She thought maybe she could use estimation to make converting from Turkish Lira to US Dollars easier.

Did you think of a good way?

Here is one way:
Ms. Hoffman knows that 0.45 is close to 0.50. (Just like 45 is close to 50 when you round to the nearest 10)
$0.50 is half of $1.00.
If 1 Turkish Lira is about half of $1.00 then about 2 Turkish Lira equal $1.00. Make sense?

Now it is easy! All you have to do is divide how many Turkish Lira you have by 2 to get the number of US dollars.

Let's try a problem now!

Ms. Hoffman bought a special Turkish towel. It cost 10 TL. How many dollars was it?

10 divided by 2 = 5! The towel is about 5 dollars. Remember, it is not EXACTLY 5 dollars, because we are estimating, but it is close!

Estimating to Make Math Easier!

Last week, Ms. Hoffman asked you how to convert Turkish Lira to US Dollars. She told you that the official exchange rate was 1 TL = $0.45. You then figured out how much 15 TL was in dollars. But, I bet you had to use a pencil and paper to figure it out! Ms. Hoffman does not always carry a pencil and paper with her (or even a calculator) when she is traveling. But, she still wants to know how much things cost in dollars. She has to find ways to do the math in her head!

With some different money, the exchange rate was pretty easy, like in South Africa. But, here in Turkey, it is not so easy. Ms. Hoffman might have to use estimation.

Can you think of a way to use estimation to make it easier for Ms. Hoffman???

Answers: How Much Time on a Bus?

Ms. Hoffman asked how much time she was on a bus. The first thing you have to do is figure out when she was on the bus.

She left Olympia at 9:30 am. 
She arrived in a town called Pirgos at 10:43 am.
She stayed in the bus station at Pirgos till her bus to Tripoli at 3:30 pm.
She arrived in Tripoli at 6:10 pm.

She was on the bus from 9:30 am to 10:43 am when she traveled from Olympia to Pirgos.

Then she was on the bus from 3:30 pm to 6:10 pm when she traveled from Pirgos to Tripoli.

Finally she was on the bus from 6:55 pm to 8:05 pm when she traveled from Tripoli to Sparta.

Let's figure out how much each of those were, and then how much it was in all!
1 hr 13 min + 2 hrs 40 min + 1 hr 10 min = 4 hrs 63 min
But wait! If you have 63 min, is that more than 1 hour?? Yes! How many minutes in 1 hour? 60, right?
63 min - 60 min (1 hr) = 3 min.

The answer is 5 hours and 3 min!
