Mean Median Mode and Range
Mean- is the average of a group numbers.
To find the average you have to first add the numbers together
Then you divide the sum by the numbers of items.
Median- the middle number in a set of ordered numbers.
You have to order the numbers from least to greatest.
Mode- is the numbers that appear most frequently in a set of numbers.
Range- is the difference between the highest number and lowest number in a set numbers

Earthquakes,Volcano,and Mountains
Earthquakes- You are in class at school, and suddenly a bell starts to ring very loudly. The teacher asks you all to leave the room calmly and walk outside to a safe place for attendance to be taken. You are having a fire drill, just as students in school do every year. Now imagine yourself sitting in your classroom and hearing the same bell ring. This time the teacher asks everyone to get under the desks. You are having an earthquake drill. Students who live in places where earthquakes can happen have earthquake drills as well as fire drills.
Volcanoes- Scientist have collected information indicating that a hot spot under Hawaii is responsible for the volcanic activity there. A hot spot location where the temperature under the crust is much higher than elsewhere. As a result lava is forced upwards, through cracks in Earth's crust. The people who live in Hawaii see lava flowing almost contonuously from Mauna Loa.
Mountains- As well as moving from side to side, faults can move up and down, or vertically. Vertical faults are called normal faults if the rock moves down, and reverse faults if the rock is pushed up. Mountain ranges are often the result of more than one kind of action. Mountains created as a result of both folding and faulting are described as complex mountains. The photos of the Rokies show folding in the rock layers and faulting in places where the layers are broken away.

FINALE PROJECT
This week we started are finale ELA project. I am reading Brian's Hunt. I have to do 4 response journals and make a book cover for the story.
Circle graphs
to draw a circle graph, you first must look at your information you have.
let's say the chart says 25%. you would have to find 25% of 360( because a full circle is 360 degrees)
so you would first divide the number by 100 so in this case 25 divided by 100 equals .25.
of means times so you would go 0.25 x 360 which equals 90 degrees.
so on your circle graph, make a 90 degree angle.
