Percentage
A percentage is a number over a hundred such as 50% & 100%. This is a percentage sign. %.
The percentage sign is made up with three basic numbers: two zeros & a slanted one. This is a
fraction for a percentage: 50/100. The best way to remember percentages is to remember what
numbers make it up.
Mostly, people use percentages to see how well something is going on or whatever.

Scary Division
Problem one: You have 13 OLG shortbreads to share fairly with your friend TukTuk (the towel). How can
you divide the fairly?
YouTukTuk
YouTukTuk
Solution: 6 for you, and 6 for TukTuk, for the remainder split into half and ½ to
you and ½ for TukTuk.
Toothpick trick
• You start out with 12 toothpicks into 3 boxes, then turn it into to a 5 square shape moving 3 toothpicks only.
Miserable Toads
• A group of toads were planning to set a record and build the biggest amphibian pyramid in history.
How many days?
Problem: Froggie fell into an ten foot
well. He climbs up 3 feet during the day, and slips 2 feet down
during the night.
Well, that wasn’t so scary.
Mixed-Up Problems

Prime and Composite
Composite numbers are number s that can be made by usinga variety of numbers by multiplying.
Prime is a number that can only be made by multiplying itself and one.

How to make Mixed Numbers
Example: You have two squares with four mini-squares in each. One of them is fully colored in. the other has only one mini-square covered
up. That’s the Mixed number

Customary System
This is a map of the world. The red area
is where the customary system
is used. The gray is the metric system.
Units and Conversions of Length• Inches (in.)• Foot (ft.)- 12 inches• Yard (yd.)- 36 inches, 3 feet• Mile (mi.)- 5,280 feet, 1,760 yards
Example of Conversions
• Feet to inches: 2 feet equals 12 inches.
Units and Conversions of Weight
• Ounces (oz.)• Pound (lb.)- 16 ounces This is an
customary, or, Celsius Thermometer. The red is alcohol
that increases its amount the more
hotter it is.
Stuff
The next scenes show someone doing an algebra puzzle. You solve
the puzzle by figuring out which shape is what number by dividing the number on the corner with the
shape.
I highlighted the column I’m working on.
18 divided by 3 is 6
I highlighted the row I’m working on.
28-6=22÷2=11
I highlighted the row I’m working on.
10-6=4÷2=2!
The End (That puzzle was solved for real!)

The Joon Shifter
There was once a point land where everyone was happy about being a
point… except one point.
I hate being a point!!!
There was once a point.
That turned into a ray.
That turned into a line.
That turned into an angle.
That turned into a triangle.
That turned into a square.
That turned into a parallelogram.
That turned into a polygon
That turned into a rhombus.
That turned into a rectangle.
That turned into a pentagon.
That turned into a hexagon.
That turned into a heptagon.
That turned into a octagon.
That turned into a nonagon.
That turned into a decagon.
That turned into a dodecagon.
That turned into a triskadecagon.
That tuned into a tetradecagon.
That turned into a pentadecagon.
That turned into a hexadecogan.
That turned into a heptadecogan.
That turned into a optadecogan.
That turned into a enneadecagon.
That turned into a icosagon.
That turned into a icosagon. And then he exploded because he had
too many sides and angles.
And he was a point again.

Average
How to do Average
Start with 3 numbers like 4, 5, 7
Then add them up.
4 + 5 +7 = 16
16 – 3 = 13So 13 is your average.
