FC: My ACT Scrapbook | Abby Martin 1st period 10.03.12

1: Table of Contents | 2-3.........Use the Answers 4-5........Super Easy Algebra 6-7.........Algebraic Manipulation 8-9.........."Mean" Means Average 10-11......Angles 12-13.......Parallel Lines 14-15.......Triangles 16-17.......FOIL 18-19.......Math Vocabulary 20-21.......More Math Vocabulary 22-23.......Multiples Vocabulary 24-25........Fancy Graphing Vocabulary 26-27........Slaloming Slope I 28-29.......Slaloming Slope II 30-31.......Using Charts and Graphs | What do you need help with?

2: Skill 1: Use the Answers | Learning how to use the answers on the ACT can help you with decision making in life. Think about the problem and what you can do to solve it!

3: When there are variables or unknowns in the question and numbers in the answer choices, just simply pick the most reasonable answer and plug it in!

4: Skill 2: | Super Easy Algebra | Even though these are super easy math problems, they can still have an effect on the way you problem solve in life. Think about the problem you are trying to solve and come up with different answers that could help, now which one of the answers would be best?

5: Just follow the rules! When you see "then x=?" just follow the simple rules or use the answers!

6: Skill 3: | Algebraic Manipulation | There will probably be multiple times during your life where there is a bunch of things distracting you from finding the answer to something. Just like algebraic manipulation, find out what the problem is asking you for and ignore all the excess distractions

7: "What is R in terms of I,P, and T?" That is just a fancy way of saying "Solve for R." "What is... in terms of...." Just solve for the "what is..." It's that simple!

8: Skill 4: | "Mean" Means Average | Knowing how to find the average of items is something that will be needed for the rest of your life. There will be multiple situations at work or at school when you will need to find the average of something. It is a basic skill that is a necessity to life and the ACT.

9: Mean=Average You find it by finding the sum of all the items and then dividing it by the # of items Mode=# that occurs the most often Median=Middle # in a list of #'s

10: Skill 5: | Angles

11: Vertical Angles are equal Angles in a vertical pair add up to 180 degrees (big equals little) All angles in a triangle add up to 180 Supplement=180 degrees

12: Skill 6: | Parallel Lines | Parallel lines are everywhere in the real world especially in roads and buildings. It is important to know that these are parallel lines to extend your vocabulary and to understand that they will never cross over.

13: Parallel Lines are two lines that never touch If two parallel lines are crossed by another line (called a transversal) eight angles form These eight angles are either big or little All bigs are equal All littles are equal Combined they add up to 180

14: Skill 7: | Triangles

15: Isosceles Triangles: Have 2 equal sides The 2 angles opposite the equal sides are also equal Equilateral Triangles: All sides are equal Each angle is 60 degrees

16: Skill 8: | FOIL

17: FOIL First, Outside, Inside, Last All you do is multiply then simplify!

18: Skill 9: | Math Vocab | Knowing math vocabulary isn't just important on the ACT. It is important in real life because it helps you understand others and what they are saying to you. Knowing these words is crucial.

20: Skill 10: | More Math Vocab

21: Factors: #'s that divide into a number evenly Greatest common factor: the largest factor shared by several given numbers Prime factors: the factors of a number that are also prime numbers

22: Skill 11: | Multiples Vocab | Understanding what the multiples of numbers are is important beyond the ACT because in the real world you may be placing an order of chairs for a wedding and realize that you have to divide them equally among tables.

23: Multiples are all of the #'s that are divisible by a certain # The Least common multiple is the lowest # that is a multiple of several #'s

24: Skill 12: | Fancy Graphing Vocab

25: Standard (x,y) coordinate plane: a fancy term for the grid you graph on Cartesian plane: the normal grid you graph lines on Ordered pair: normal (x,y) coordinates Defined/undefined: violate the math rules

26: Skill 13: | Slaloming Slope I

27: When a problem gives you two ordered pairs and asks for the slope, just use the simple formula, see picture->. The slope of a line measures it's steepness. The slope of a line is often called the "rate of change>"

28: Skill 14: | Slaloming Slope II | Slope is useful for real life because you may be trying to figure out how tall a tree is and if you measure it's shadow and figure out it's slope, you can find how tall the tree is.

29: Parallel lines have equal slopes. Perpendicular lines have negative reciprocal slopes. In this problem, you solve for y.

30: Skill 15: | Using Charts and Graphs | Charts and graphs are useful to the real world because if you cannot read graphs, you are going to have a hard time reading Presidential polls.

31: The key to charts and graphs is to read the intro material and the "note" if there is one, and to expect an average, percent, and/or probability question about the data.
