Are you an IB student taking Mathematics Standard Level (SL)? Well brace yourself because it is considered to be one of the toughest subjects in the curriculum. The syllabus comprises of 6 topics and students are externally and internally assessed.

Original: Source

The Internal Assessment (IA) in Math SL is known as Mathematical Exploration. It is a written work that requires students to investigate an area of mathematics. As per the International Baccalaureate Organization, this assignment “encourages students to take a considered approach to various mathematical activities and to explore different mathematical ideas.” Don’t make the mistake of taking it lightly because it contributes 20% of your final grade.

Consisting of 6 to 12 pages, the report needs to be focused on a particular area of mathematics. The idea is to accurately demonstrate your knowledge through comprehensive mathematical writing, constructing logical arguments and drawing conclusions with the help of diagrams, graphs and mathematical formulae.

## Here’s How You Can Ace Writing Your Math Internal Assessment

Original: Source

Yes, we understand this can all be very overwhelming. Here are 4 key tips to help you write an impressive math IA.

### Choose a Topic of Interest

When you choose a topic that is genuinely of interest to you, it reflects in the final outcome. The same applies to your math IA. Studying mathematical concepts is one thing but correlating it to abstract and real-world situations is another ballgame altogether.

So, when you are brainstorming topics, select one wherein you can put your mathematical skills to use to pose a solution. It should be a topic that excites you and no, this does not just mean mathematical topics such as algebra or statistics, it can also be related to basketball or any other field that can be explained using mathematical techniques.

### Stick to the Criteria

Many students make the mistake of complicating matters by using complex mathematical concepts that are out of syllabus. This is never a good idea and only results in a waste of time.

The surefire way to approach this assignment is by sticking to the syllabus to demonstrate your knowledge. Keep things simple and ensure you meet the 5 criteria – Communication, Mathematical Presentation, Personal Engagement, Reflection and Use of mathematics.

### Establish a Clear Structure

How well you structure your writing is what makes up the ‘Communication’ and ‘Mathematical Presentation’ criteria so work on a logical structure before you get down to drafting. This is the flow you can adhere to while writing your math IA.

*Introduction*

- Clearly highlight the objective and significance of the topic
- Justify the choice of topic
- Briefly mention the area of mathematics that will be explored

*Body/Mathematical Exploration/Mathematical Processes*

- Describe the method of exploration
- Share results using graphs, lists, tables, diagrams, etc.
- Analyze the findings and form conjectures

*Conclusion and Bibliography*

- Summarize the findings and relate it to the objective of exploration
- Mention limitations, if any
- Make real life connections and possible extensions in relation to personal experience
- Reflect on what you have gained from this exploration
- Cite references in the bibliography

### Start Early

IB’s Math IA is not something that can be finished in a couple of hours. In order to do it full justice, you need to begin early.

There will be instances when you won’t be able to due to multiple assignments or will find yourself stuck while writing, at such times, it is best to get help with your Math IB IA paper. We at Writers Per Hour can help you deliver a professionally written and well-articulated math IA paper as per IB standards within your stipulated deadline.
