My Electrified Math
Math plus computer = electrified math!
Can you solve this?
obviously
Can you solve this?
2+2=?
NO WAY!
Do you see this pattern?
5x10=50
5x100=500
5x1000=5000
5x10000=50000
The pattern is adding a zero.You can figure out a problem like
those like this.
This is going to be our problem. First you do 5x5=25. Then you add all the zeros of the problem at the end of 25. So it would be 2,500.
The Möbius Strip
As you will see in the next slides I will divide. I will have thirteen cookies and I will share with you. All I had have to do is split the Oreos with you.

How to Find an Average
First you add up all the numbers. So here 1+8+9=18
1
8
9
+
Then you divide the sum be the number of numbers in the problem.
18 divided by 3 equals 6. So that’s the answer!
Follow the Bouncing Ball
A ball rebounds one half of the height from which it is dropped. Assume the ball is dropped from a building at a height of 138 feet. How far will the ball bounce up it when it bounces the fourth time?
8 ft!!!!!!!
Factors
• Factors are numbers that go into a number.
• If a number is even two will have to be a factor.
• For example 12.
• The factors of 12 are 2,3,4,6,1,12.
• Get it?
• If you don’t go onto the next slide.

How Many Days
• Froggie fell down a ten foot well. He tries to hop out. It doesn’t work. He has to climb out. Every day he climbs 3 feet and every night he falls back 2 feet. How many days will it take Froggie to climb out?

Areas and Perimeter
• The area of a shape is the space inside a shape.
• The perimeter is the length around the shape.
• In the next few slides I will show both the area and perimeter.
Now that was the
perimeter
Let’s go again. This time you
guess what the perimeter is.
You say it’s 14? Let’s see if your right.
Yes, you are right.!
This time you think it’s 20. let’s check
this last time.
What is the area of the rug?
13.6 meters
10. 7 meters
145. 52 sq ft, THAT’S RIGHT!
How to find Volume
You do the length times the width times the height.
Now I will show you an example.
What is the answer?
Length
2 cm
Width
4 cm
Height
3 cm
24 cubic cm, that’s right!!!
Since you’re doing so good let’s make you do a cube.
The length is 4 the width is 4 and the height is 4. What is the
volume?
64, wow you’re on fire. Well I guess that’s it on volume, bye!

Prime and Composite Numbers
• A prime number is a number that can only be divided by itself and one, for example 3. 3 can only be divided by 3 and 1.
• Composite numbers are numbers that can be divided by one, that number, and any other number(s).
• In the next few slides I will show you numbers and you have to guess if it’s Prime or Composite.

Percentage
• A percentage can be something from discount on clothes, to a grade on your report card.
• A common percentage is 50%. It is the same as saying .
• In the next few slides I will try my best to explain more about percentage.
• Watch and learn!!!

Mixed Numbers
A mixed number is a fraction combined with a whole number. For example 1 . The one is the whole number, and the was the fraction.
In the next few slides I will show you some mixed fractions

This equals :
1 3

Or
3.3
In the next slides I will teach you how to do a algebra puzzle.
This is what it will look like when you get started.In these
puzzles you have to
figure out what the different shapes secret
number is.
Then you raise the bar on the right to the number that they stand for,
How you know what they stand for is by the numbers on the
right and bottom.
See those oranges, they are thirteen
because 39 divided by 3 is 13.
Then you can solve the rest of the
puzzle.
Real Algebra
• In the next slide I will show you how to figure out the following problem.
• One number is four times another. Their sum is 55. Find the numbers.
• First you make a variable, for example x. X plus 4x =20.
• Then you add the x’s so in this problem we have five x’s.
• Then you see how many times 5 goes into twenty and you get four. So x equals 4.
• So that means 4x equals 16. so your answer is 4 and 16.
• Then if you want you can celebrate.
This can be a teachers way of saying 3X4=__ this is called a math
triangle.3

This is a new 2009 penny.
• E PLURIBUS UNUM means one out of many.
• It has a mass of 2 grams.
• Its circumference is 6.28318 cm.
• Its diameter is 2 centimeters.
• Its radius is one centimeter.
• Its area is 3.14159.
• It has 2.5 % copper (CU).
• It has 97.5% of zinc (ZN).
The Never Satisfied Shape
First the shape was a point. He was very happy getting to be in a lot of different places. But soon, he was tired of being a point so he went to
the shape shifter.The point
Then the shape shifter turned him into a ray. He was happy being a line all around the world. But soon he was tired of being a ray so he
went to the shape shifter.
Next the shape shifter turned him into a line. He was very happy
being a line and traveling in the air. Soon he was tired of being a line so
he went to the shape shifter.
Next the shape shifter turned him into an angle. He was happy
getting to be in cool places like a computer screen. Soon he was
tired of being an angle so he went to the shape shifter.
Soon the shape shifter had turned him into a triangle. He was
satisfied being a triangle and getting to go to Egypt in pyramid
form. Soon he was tired of being a triangle so he visited the shape
shifter
Next he was turned into a square. He definitely liked being a T.V. Although he could turn into such
cool things he soon was bored so he visited the shape shifter.
The shape shifter turned him into a pentagon. There wasn’t much to
do so he decided to be in a children’s text book. He easily got
bored so he went to the shape shifter.
Next the shape shifter turned him into a hexagon. He got to be honey comb. But of course, soon he got
bored and went to the shape shifter.
Next he was turned into a heptagon and was a quilt. But he was bored
so he went to the shape shifter.
Next he was a octagon. He really enjoyed being this octagonal
Rubik’s cube but got bored. So he soon went to the shape shifter.
Next the shape shifter turned him into a nonagon. He soon was bored
of being wrote on teacher’s black bored so he went back to the shape
shifter for the last time.
Next the shape shifter turned him back into a triangle and he chose
never to change again.
