The Following presentation was created for the Applications and Interpretations SL course but can be used for any course such as A-levels that teach this topic. I have included exam question from both A-Level and the IB in the Presentation.
The PowerPoint goes through the following:
-linear sequences from GCSE
-the nth term formula
-embedded simultaneous equation problems
-inequality problems
-introduction to series and proof
-both forms of writing the sum formula
-sum problems involving inequalities
-sigma notation
-basic summation properties
Throughout the PowerPoint there are worked examples along with exercises for students. I have also included a few video exam solutions with videos going through addition examples for students. There is also a video explain how the Arithmetic Sum formula evolved. At the end of each section I have included IB exam questions so students get get practice to the types and style of questioning they should expect to see when they write their exams.
