For the last few months I've been volunteering at my daughter's high school to help the 12th graders review for the International Baccalaureate (IB) Maths Standard Level Exam in May 2015. In the process I produced these review notes that I thought could be useful to other students preparing for the exam as well. Review Notes for IB Maths Standard Level I'd be grateful if you email me with any mistakes you find so I can correct them. Best of luck on the upcoming exams.

Hi guys! I am currently working on my Math IA and I am really struggle to find a good topic (I am in Math SL Y2) I think I will mainly focus on population curves in different countries (birth rate and death rate), whether it is more like of a quadratic, cubic or exponential curve, and I asked my teacher and he suggested to use integration and differentiation equations for this topic. However, I am not really sure in which direction can I go with this topic, like what I am proving or what conclusion I try to reach, and how do I apply the concepts or equations of integration and differentiation... If someone can reply to my question, I am really appreciated and ca…

Hey, so today my teacher has introduced the IA to the whole class. She also said that It could be about anything as long as math relates to it... Long story short, I really need help in deciding on a question but I can't really think of anything. I was really interested in doing it on a MMORPG like world or warcraft or some game of that sort but also was looking at doing it on the game on all android / iphones called "Tap Titan". I've learnt that there are many formulas that are taken into consideration to leveling up the characters, how much damage you do, how much money you earn and the HP of the monsters and bosses and many formulas of that sort. So what kind of ques…

I'm rather confused if its required by the IB, on penalty of losing marks, to always leave answers in 3 significant figures. Different sources tell me otherwise: a mark scheme from the old Maths SL syllabus (pre2014) states that a 1 mark for inaccuracy be applied to the whole paper, once, if there is any instance of inappropriate significant figures in the answer. However, the mark schemes for the current syllabus are very vague regarding this, and I cannot interpret anything whatsoever. My Maths teacher is also rather unsure about the importance of significant figures, whereas DP coordinator says you can leave your answer to 99999 significant figures if you really want…

In this exploration, I want to see how mathematics is used to "predict" price movements by financial traders. This is very interesting to me as I want a career in Finance. Furthermore, I want to explore particular events such as the fall of the Lehman Brothers etc. and view correlations between stock valuation, output and market volatility. I also aim to find out what sort of correlations there are in particular stocks. I will use technical analysis (stats) on a particular stock index to find these price trends. The majority of the maths required in financial markets & trading is probability, statistics & stochastic calculus. The BlackScholes equation (alth…

So I'm trying to come up with a topic for my SL math IA and I'm currently working with the idea of modelling the population decrease of nesting leatherback sea turtles in Las Baulas. I plan on creating an equation to predict the further decrease of the population if humans do not intervene, and possibly seeing what type of graph this population matches. The only issue is I can't decide if it is more of a science IA or a math IA. Any thoughts??

hello there, I'm an ib student from tokyo and I'm currently learning maths sl from the haese mathematics text book "third edition". My school has 8 ib students and we're one of the first to do the ib program in Japan. We all have the text books but the problem we have is that we don't have the solutions book. I asked the teacher if the school could buy them but apparently the states and Canada don't ship them over to Japan. So, the current situation we are in is studying without the solutions! It's very inconvenient without the solutions and frustrating when we don't get the answer right and don't have the solutions! If someone out there has the solutio…

Hello, I hope you are doing well. I need to do my Math SL IA on SIR model. (Simulation of pandemics) There is a hypothetical and isolated country with 10 million people. Then, there are 10 immigrants who entered this country and 5 of them are infected. R0 is 3, and I am varying the immunity rate. My research question is how does the immunity rate affect the spread of the virus? I am having difficulties in simulating a mathematical function which will simulate the behaviour of this case with SIR model. Could somebody please help me to translate this case mathematically?

For May 2020 results, did anyone else notice that their SL Math grade was much lower than their predicted? My SL math grade was 2 points lower than what was predicted, and I have never received a grade this low in any Math IB coursework. It’s not like I didn’t put much effort into my IA.....can anyone else relate?

Hey guys, I have a Math IA due on Sunday December 15, which is about 9 days from now. I want to do my topic on the golden ratio because firstly, I'm genuinely interested in it, and secondly, it's extremely risky to change topics at such a late stage. I know some of you will scold me for procrastinating on it but believe me I've legitimately been working on it. However, I'm having trouble finding an original idea based on the golden ratio. I did an introduction where I introduced it and such but I'm having trouble with how to proceed. I know it's supposed to be an exploration on a reallife thing because I looked at past IAs; even my teacher said that my topic is good but…

Hello everyone, currently I am writing a new math IA and i decided to write it under the topic of Projectile Motion. What what I want to do is take a video of a setter (in volleyball) and him setting the ball up. I'll take that video and create a graph and will derive that function. The thing is, I think that this is a little to vague, and I really don't have a clue on what to really explore within my topic. For the volleyball idea, I wanted to originally see what's the best place to put the ball in the air to get a good hit in for the spiker. If you have any further suggestions on what else I should do with this topic, I am open to any suggestions. Thank you!

Hi, I need to find ideas for my MATH SL IA and want to do Probability. My 2 ideas are either Probability in testing in medicine (false positives). Problem is I don't know what to do with the idea (what math to use) Normal distribution (any topic, just measuring distribution). If you could help me with ideas on any of the two as in what topics to include to get the highest grade I would be thankful. Is it enough to do a Chi squared test, normal distribution graph and use the equation? (for Normal distribution idea) Please I need urgent help and thanks

Hi guys, My name is Aurimas, I'm a part of a student venture tackling education inequality and we're looking for Maths SL students to participate in our program. We have developed a test system that would provide a detailed and visual assessment of your skillset and help you objectively identify gaps in your knowledge. We are looking for students to complete these tests and send us back the solutions, which we would grade for free and provide you with the personalised skillset analysis. I'm attaching here how the skillset document would look like. Let me know if you would be interested or have any questions.

Hello, I am not sure if peerreviewing math ia's are exclusive to my school but upon giving my math ia to another student to "premark" they return it very shortly thereafter saying it was too difficult. I asked three more people to look at it and they said the same thing. Asking two more people shows that my conclusion is truepeople don't understand the mathematics that I am using in my math ia. This is a problem because if the teacher (who is currently absent) does not understand it either I do not have much time to fix it (since the final copy is due quite shortly after the draft is passed back). I have already given the teacher a prepre draft to look at but they di…

MATHS IA HELP  TIDAL WAVES?

I have currently chosen to investigate tidal waves for my maths IA. However, I am unsure as to what other explorations I can do under this. (And whether or not this is too simple...) Is modelling and predicting future tidal waves appropriate? I have secondary sources that'll give me data of tides at different points in times at a beach, so I will be able to graph them. I will also use trig and algebra to find the ideal time to visit the beach with my "ideal" tidal height of 1.5 metres I am uncertain as to what other maths/exploration I can apply to this Any suggestions would be greatly appreciated!

Hello! Math has lately been my weakest subject, and sadly, we have an Exploration to write. Our first draft is supposed to be handed in tomorrow. I have already written 67 pages on my IA. However, my topic is "Patterns in Pascal's Triangle", and it just occurred to me that it may be a weak topic... What do you think? I am basically out of ideas, and I think it might be too late to change topic. The Pascal's Triangle was something I just chose to write about because I found it quite interesting when we learned about this, but not something I am very excited about. I would appreciate any answers, ideas, tips... whatever! I just want to finish it, and get a decent …

Hi! I'm currently thinking of a good topic for my Math Exploration, and I decided to take "The Handshake Problem" as my topic. However, I do not know exactly how to outline/start my IA. Like, i was thinking of applying the "N choose R" in it because we actually discussed that in class. But, I don't know how to make my IA even more sophisticated from then on. I was also thinking of applying this in a more practical sense, like "how many handshakes in a certain country," but isn't that too simple because i will simply just use the formula? Or, how should I explore the exponential growth (curved graph) of the increasing values of the handshake problem? But, I don't exac…

I was kind of wanting to just do "Patterns in Pascal's Triangle" and select 3 or 4 patterns that I'd explain and prove in the IA. Would this be okay, or does it have to relate to real life? Because I noticed a lot of the examples found a way to realworld subjects, like nature or rainfall for instance. I was planning on showing personal involvement by talking about my interest in finding patterns and the like, and some independent thinking when it comes to the patterns in Pascal's Triangle. Would this topic be okay?

Hi, My maths IA plan is due in a week and I am having trouble figuring out how I could further my investigation. My idea is to apply calculus and the principle of Optimization to minimize surface area to volume ration of a house. Does any one have any good ideia to how I could go beyond finding the optimum surface area to volume? Maybe an additional area of mathematics would be good. I would really appreciate it if someone could help me. Thank You

So a while ago I started my IA on the subject of MC Escher's Tessellations. However I have realized for too late I have run into a horrible snag. I feel as if the mathematics that I am using in my IA are not nearly as complex as they should be for Math SL. Essentially, I decided to use a variety of transformations to illustrate how Tessellations can be created. I then created my own using a series of transformations. (Specially I created a Tessellations with triangles). While my teacher advised and approved of me to do this, I feel I have made an accident and it will cost me gravely in my Mark scheme. Is there a feasible way I can improve this or should I scrap it and do …

Hi, Now my teacher asked us to find a topic for our math exploration (IA) and he told us that it has to be something that we like. Now I like airplanes (jets, airbusses...etc) and I found more physics than math on the subject when I searched on Google. So my question is if there's any math behind airplanes, what level is it and what type (algebra, calculus..etc). And if there's not any math or Little math what topics can I choose instead? Thanks.

Im a hl maths student and i wanted to do my maths IA on a topic related to calculus as that was the option that my school choosed. And i came across optimisation of packagings. However ive seen that many people simply use the differentiation method to find the optimum surface area of the cans or products they are investigating. Hence to make it more complex i would want to use a unconventional theory or equation such as the brachistrone theory to find the optimum surface area of a can. Is it possible are there any other theories that i can use? and should i find the optimisation of a can or are there other things that i can find the optimisation of? or is this too simple,…

The Brachistochrone problem  I'm really interested in this problem but the problem I have with it is that I'm not sure if it is way out of the scope of the maths SL syllabus.

From what I've seen this is primarily a question of…
