Analog Clock 60 min= 1 hr 30 min= __1__ 2 hrs 15 min= __1__ 4 hrs ex. Mrs. Shami is using a small clock to demstrate what time it is. The time she uses are:

9:00 (9 o'clock) 9:15 (Quarter after 9, 15 mins after 9) 9:30 (Half past 9,30 mins after 9) 9:45 (Quarter of ten, 15 min 'till 10, 45 mins after 9)

//**Units of Time**//
1 minute = 60 seconds 1 hour = 60 minutes 1 day = 24 hours 1 week = 7 days 1 month = about 4 weeks 1 year = 52 weeks 1 year = 12 months 1 year = 365 days 1 leap year = 366 days 1 decade = 10 years 1 century = 100 years 1 millennium = 1,000 years

//**Elapsed Time-**//
is the ammount of time that passes between the beginning of an event and the end of the event.

ex. Start 1:00 Ends 2:30 total 1 hour 30 minutes Start 10:45 Ends 1:05 total 2 hours 20 minutes / 10:45am-12:45pm=2hrs 12:45-1:05=20 minutes Start 11:50am Ends ..?.. He ran 2 hrs and 22 minutes Ends = 2:12pm

 * Vacation** The Arnolds are leaving for vacation on the first Saturday in August. They will be gone for two weeks. What date will they return home?

Move down one row on a calendar and you have counted on week or seven days. Move down two rows for two weeks. The Arnolds will return home on August 18th. Numbers like first, sixth, and eighteenth are ordinal numbers. Ordinal numbers are used to tell order. August 10th is the second Friday in August.

Example: What date is one week before August? Find August 24 on the calendar. Count up one row. One week before august 24 is August 17.

//Line Plots//
A line plot displays data along a number line. Each X represents one number in the data. In the line plot below, each X represents one zoo. x x x ↓ outliner xx x x x x x 10 15 20 25 30 35 Zoo Budgets in Millions Dollars
 * ←l--l--l--l--l--l--l--l--l--l--l--l--l--l--l--l--l--l--l--l--l--l--l--l--l--l→**

Read the line plot. Since there are 2 Xs above the 16, 2 of the zoos have budget of $16 million. The most Xs are above the 15, so the most common budget is $15 million. The greatest budget shown is $33 million and the least budget is shown is $12 million.

An outliner is a number in a data set that is very diffrent from the rest of the numbers.

Identify the outliner in the data set to shown in the line plot. in the line plot, the number 33 is far away from the rest of the data. The budget of $33 million is an outliner.
