At the time, the RMS Titanic was the largest passenger steamship in
the world. The Titanic used some of the most advanced technology
available and was believed to have been "unsinkable.”
At 11:40 PM on the cold night of April 14, 1912 the Titanic struck an
iceberg on her maiden voyage from Southampton, England en route to
New York City.
Two hours and forty minutes later, she sank beneath the waves of the
icy North Atlantic carrying over 1,500 souls to her grave, 2.5 miles
below the ocean’s surface.
Only 705 people survived what was considered the worst marine
disaster in history.
Captain Edward John Smith

From Captain Smith, just moments before the Titanic plunged into the sea:
“Men, you have done your full duty. You can do no more. Abandon your cabin. I
release you. Every man for himself”.

Exactly how Captain Smith spent his last minutes alive is pretty much a mystery.
Theory 1) A rich Philadelphia banker reported that Smith remained at his
post on the bridge and went down with the ship, showing no
panic or fear whatsoever.
Theory 2) One of the Titanic cooks, a fireman, and a passenger named Charles
Williams all claimed that shortly after the sinking, Captain Smith was seen
swimming around the icy waters with an infant in his arms.
When their boat went to rescue Captain Smith, he handed them the child,
but refused to get in himself. He then pushed himself away from the
lifeboat, and slowly sank from sight.
Isaac H. Maynard
Entree Cook , RMS Titanic
April 30, 1912
Maynard was rescued on Lifeboat B. The Press later labeled
him as, “The steward who took the baby from Captain
Smith's arms”. This was following unconfirmed reports
that Smith had delivered a child to the boat before
swimming off to his death.

The Titanic sank and was never to be seen again, her exact
whereabouts unknown, until September 1, 1985 when she was
discovered by deep sea explorer Dr. Robert Ballard.
The titanic was discovered 3,925 meters (2.5 miles) below the
surface of the ocean.

Integers are the whole numbers and their opposites.
…-3, -2, -1, 0, 1, 2, 3…
NO
Is -.25 an integer? Answer: _____
Two numbers that are the same distance from 0 on a number line
are opposites.
-2
What is the opposite of 2?
Answer: _____
5
What is the opposite of -5? Answer: _____
You can “plot” integers on a number line to help you put them in
order.
The further to the left a number is on the number line, the
SMALLER it is!
Example: -7 < -2
Mr. Smiley is going to help us order some integers.
1)
Plot the following integers on the number line:
-3, -1, -4, 2
2)
Order them from least to greatest:
-4, -3, -1, 2
Answer: ________________________
1) Plot the following on the number line: -4, 8, -2, -6, 3
-6, -4, -2, 3, 8
Then order from least to greatest. Answer: ________________
>
2) Use <, >, or = to compare the integers: -280 ____ 49
3) Order the following from least to greatest without using a
number line:
25, 16, 0, -1, 10, -4, -32
Answer: _________________________
- 32, -4, -1, 0, 10, 16, 25
