Here are Mr Wagner’s old sites – they have the worked solutions for November 2009, as well as other review things.
And here are the questions for November 2009:
Here are the ultimate review study guides for SL and Studies.
SL ULTIMATE REVIEW – MAY 2013 (Study Guide)
Answers – coming… hopefully soon. I lost them. 😦

Here is the study guide for vectors. It’s really straightforward – you either know these or you don’t. If you’re having trouble, first try to look it up in the book BEFORE looking at my answers. That will help you learn more.

4/9 and 4/10 Exercises – Calculator and Paper Required!!
- Basic Set Notation
- Use hints the first time through, then second round should be a “cinch”
- Counting 2 (yes really)
- Use hints the first time through
- The original purpose of nCr! Use the number given as n and the number of spots as r – it’s really cool. Think back to flipping a coin to understand how it’s like Pascal’s triangle: 1 coin : 1, 1 – 2 coins: 1, 2, 1 – 3 coins: 1, 3, 3, 1
- Permutations and Combinations
- You just have to pick which question type it is and apply what you’ve learned!
- Probability space
- Probability 1
- (slow down on the target questions!)
- Probability with permutations and combinations
- (some of these are binomial and some are not – the ones that are not require tree diagrams. whichever it is, give answer as fraction)
- Dependent probability
- (use a tree diagram! or if there is a “given” remember “given” means “denominator”)
- Independent probability
- Expected Value
- Mean Median and Mode (yes really)
- Average Word Problems
- Creating Box and Whisker Plots
- Empirical Rule (Normal Distribution)
- Z Scores 1 (N.D.)
- Z Scores 2 (N.D.)
- Z Scores 3 (N.D.)
You can get 2% on a test or 7% on a quiz or homework assignment for each one on which you reach “proficient.” Even if you hit that blue bar, be sure to go to your profile and look at your Skill Progress to make sure it’s dark blue for proficient.
These are due by Thursday in class for them to count for Q3. To find each one, just type the title into the search bar and click the Exercise on the menu that comes up.
- Mean Median and Mode
- Exploring mean and median
- Average word problems
- Creating box-and-whisker plots
- Exploring Standard Deviation
- Standard Deviation
- Estimating the line of best fit
Hi SL! If you’re looking for the last chance for extra credit for the quarter, here it is: Matrices on Khan Academy!
I will give you 2% on a test grade for each Khan Academy matrices exercise you complete – up to 90%.
GO TO THIS PAGE to see the matrices topic: Items with a star are exercises. You should know how to do all of the following in addition to solving systems of equations using matrices. They are all super easy.
- Matrix Dimensions
- Scalar Matrix Multiplication
- Matrix Addition and Subtraction
- Matrix Transpose
- Defined and Undefined Matrix Operations (e.g. when can I multiply?)
- Multiplying Matrix Times Vector
- Multiplying Matrix Times Matrix
- Determinant of a 2×2 Matrix
- Inverse of a 2×2 Matrix
- Determinant of a 3×3 Matrix
That is up to 20% improvement on a test grade, which is huge. Matrices are easy – use them to help yourself!
The last day for you to tell me that you have finished them is this Thursday 4/4 in class. Please check before you tell me that you have actually reached “proficient” and not just the “review” level. To check, click on your user name at the top right, then click your profile, and check the Skill Progress. If it’s dark blue, I will give you the points. If not, try more.
As of the 2013 test, IB Math SL covers the following objectives in Topic 1 (Algebra):
- Arithmetic Sequences and Series
- Geometric Sequences and Series
- Sigma (Summation)
- Binomial Theorem and Expansion
- (Quadratics – covered more in Topic 2)
- (Exponents and Logarithms – covered more in Topic 2)
Topic 1 – Algebra (this is the chapter summary and review problems, not the H&H review). You have a stapled copy of all the skill checks and answers from class; I can also email it to you if needed.
In addition, you can practice (and earn points on the MQ1 grade in the gradebook) for 2% for each of these Khan Academy algebra exercises you solve. To see whether it’s at “proficient,” click your username twice on the KA site to go to the user profile, then click “Skill Progress.” If it says “review,” that’s fine – it just means the site thinks you need extra practice. Practice Makes Permanent!
There are not exercises for Geometric Series (finite or infinite), nor for Binomial Theorem. For those, you will need to work on review separately. However, I would recommend you watch those videos. Simply type “binomial theorem” into Khan Academy’s search bar and the videos will come up. If you want to watch them on campus, let me know which videos ahead of time, and I’ll download them into a dropbox folder for you to access.
WE CAN DO THIS! 🙂
First of all, if you are off-campus, you should definitely hit up YouTube for review. Simply search for “IB Math Quadratics Review” and you should find some good stuff.
You should also use the H&H textbook. Really.
Anyway, here are the recommended reviews for quadratics on Khan Academy
Here are the things we learned in calculus:
- Limits (both with denominator = 0 and limits to infinity)
- Power Rule (differentiating a polynomial)
- Tangent and normal line equations
- Second derivative and the magic chart (max/min/inflection)
- Chain Rule
- Product rule and quotient rule
- Rates of change/kinematics (acceleration/velocity/displacement – ISVAD!)
- Graphing the derivative
- Exponential calculus (chain rule or u-substitution)
- Logarithmic calculus (chain rule or u-substitution)
- Trigonometric calculus (chain rule or u-substitution)
- Indefinite integrals
- Finding “C” from an indefinite integral given a point
- Definite integrals and area
- Area between two curves
- Volume of revolution
To review this more on your own, watch videos, practice online (instant feedback), and practice IB problems:
- Khan Academy Practice (note K.A. only has practice in differentiation, not integration)
