15. 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.

16. Mostly, people use percentages to see how well something is going on or whatever.

20. Scary Division

21. Problem one: You have 13 OLG shortbreads to share fairly with your friend TukTuk (the towel). How can you divide the fairly? You TukTuk

22. You TukTuk Solution: 6 for you, and 6 for TukTuk, for the remainder split into half and ½ to you and ½ for TukTuk.

23. Toothpick trick You start out with 12 toothpicks into 3 boxes, then turn it into to a 5 square shape moving 3 toothpicks only.

25. 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.

27. Well, that wasn’t so scary.

28. Mixed-Up Problems

29. The ball is dropped from a 128 foot building. Each time it bounces half as much high as where it was dropped. How much will the ball bounce on the fourth bounce?

30. 128 ft. 64 ft. 32 ft. 16 ft. 8 ft.

31. These are not polygons

32. Prime and Composite

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

55. Stuff

56. 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.

58. I highlighted the column I’m working on.

59. 18 divided by 3 is 6

60. I highlighted the row I’m working on.

61. 28-6=22÷2=11

62. I highlighted the row I’m working on.

63. 10-6=4÷2=2!

65. The End (That puzzle was solved for real!)

103. That turned into a icosagon.

104. That turned into a icosagon. And then he exploded because he had too many sides and angles. And he was a point again.

105. The End

107. Money Fractions

108. 25 cents = ¼ = 25/100 50 cents = ½ = 50/100 5 cents = 1/20 = 5/100 1 cent = 1/100 100 cents = 1 = 1/1 10 cents = 1/10 = 10/100

109. Average

110. How to do Average

111. Start with 3 numbers like 4, 5, 7

112. Then add them up.

113. 4 + 5 +7 = 16

114. 16 – 3 = 13 So 13 is your average.
