Number of the Day 17-25
The number of the day is 8675.309
17) Using the digits in the 1s and the 10s place respectively make a two digit number and write the prime factors.
Because of respectively make a two digit number you have to use the order that they said first which was the ones place, so the number in the 1s place is 5 then the 7 is in the 10s place. Now you make a number using that order so 57.
Because the prime factor itself is a prime number the only factors are 1 and itself.
So the prime factors are 57 and 1.
18) Add negative 2 to the digit in the 10s place using pictures.
-2+ 7=5
Diagram: There is two negatives - - and there is 7 postives + + + + + + +
So its asking to add them together. If your adding a negative number and a postive number what ever number in the equation is bigger thats the kind of number you'll get. Ex. -3+4.
4 is bigger than 3 so the symbol you'll have a postive. So now you have to make a zero pair. You have 2 negatives and 7 postives. You have enough +s so you put 2 negatives and postives together -+ -+ and you imaginaryly throw them away. Now you are left with +++++ and thats your answer.
19) Subtract negative 3 from the digit in the ones place using pictures
5-(-3)= +2
This is because you have five positives +++++ and 3 negatives - - - . Then you have to take away negatives, so you have enough postives so you make your zero pairs. So you end up taking away 3 zero pairs. +- +- +- and your are left with 2 positives + +. and thats you answer!!
20) Write a fraction using the 1000s place as the denominator and the tenths places as the numerator.
8675.309 in this number 8 is in the thousands place and 3 is in the tenths place.
If 8 is the denominator then its at the bottom blank/8 so now 4 is at the top 4/8 you can still simplify this into 1/2.
21) Use any 2 digits to make an improper fraction.
Just to remind you an improper fraction is a fraction where the numerator is bigger than the denominator.
So now you just choose 2 numbers where the numerator will be bigger than the denominator. Like: 8/5 , 7/6 and 9/3. You try and find the rest of the improper fractions.
22) Use any digits to make a mixed fraction.
A mixed fraction is a fraction where it has a whole number and a proper fraction.
Now just choose a number for a whole number, and number for a numerator and a number for the denominator. Make sure the numerator isnt bigger than the denominator or that will become a improper fraction. Like 3 4/8
23) Write the answer to the number 22 as a decimal.
3 4/8 So you first you know that you can simplify it so 4/8 is now 1/2. so its 3 1/2. Now you divide, so 1 divided by 2 then you'll get .5. Now you have the whole left so its 3.5
24) Draw a picture to represent the answer to number 22
Okay now you had 3 4/8 right? So there was 3 wholes, and 4/8 when i drew mine I did mine simplified into 1/2.
25) Write the answer is 21 as a percent.
Because there was alot of ways to make an improper fraction I will just pick one.
6/5 is my improper fraction. So now you just divide the numerator with the denominator. So its 6 divided by 5 is 1.2 then you multiply it by a hundred.
OR
You can do this...
Here is a song that will help you with integers.
If This video doesn't work just go to this link to see the video !!!!!!! INTEGERS!!!
And If my post gets all spaced again it just does that by itself sometimes.
Here is a game to help you with adding and subtracting integers because I think that is the hardest thing to do in this whole thing. XD

Number of the Day (8-14)
Number of the day: 1234.567
8. Power- A base with an exponent is a power.
- Write a power using the digit in the 100th (1234.567) place as the base and the digit in the 10s (1234.567) place as the exponent. 6³
9. Power in factor form
- 6 x 6 x 6= 216
- Six ,three times...not six times three.
10. Cube - means three dimensional (3D)
- L x W x H = N(umber) x N x N = N³
- Cube the digit in ones place - 4 x 4 x 4 = 4³
11. Squared - means it has two dimensional (2D)
- L x W = N(umber) x N = N²
- Square the digit in hundreds place - 2 x 2 = 2²
12. Use a calculator,
- 1234.567 ÷ 3.55 = 347.7653521
14. Prime numbers- numbers with 2 factor, one and itself, not 1 or 3 more.
- 3, 5, 7 are prime numbers of 1234.567
Try this number to practice number 8 - 14: 8749.294
Sorry I can`t find a video and a link for this scribe post.

- Rounding numbers...
- Look at the given nearest place value...
- Make the numbers that end in 1 through 4 into the next lower number that ends in 0. For example 74 rounded to the nearest ten would be 70.
- Numbers that end in a digit of 5 or more should be rounded up to the next even ten. The number 88 rounded to the nearest ten would be 90.
13. Product- is an answers into a multiplication question.
Digit - a part of a number, a symbol to represent the number.
- Product of all the digits (use a calculator) - 1 x 2 x 3 x 4 x 5 x 6 x 7 = 5040
- Forget about the decimal.
- Remember if there is (are) 0 digit(s) in the number the answer is 0.14. Prime numbers- numbers with 2 factor, one and itself, not 1 or 3 more.

Notes for April 12, 2011
Interpret Circle graphs
-circle graph is a graph that represents data using sections of a circle
Sector
- sounds like section
- a section of a circle formed by two radii and the arc of a circle connecting the radii
A sector is a percent of the whole
Creating circle graphs
Central angle
- an angle formed by two radii of a circle
- the vertex of the angle is at the center of the circle
How many degrees in a circle
-360 degrees
- 2 protractors
Here is a link about circle graph
Notes for April 4, 2011
Circle
Parts of the circle
Radius- the distance from the center of a circle to the edge, represented by the variable r
Diameter- the distance across a circle through its center, represented by d
Relationship between radius and diameter
-diameter is twice longer than radius
- radius is half of diameter
Constructing circles
1. compass
2. trace a circle
3. string
Concentric circles
-same center point different radius
Circumference
- the distance around the circle
- usually represented by c
- this is a linear measurement
pi
- the ratio of the circle of a circle to its diameter
- approximate 3.14
