How to explain concepts of limit and continuity to non-mathematical students

How to explain fundamental concepts of limits and continuity to a non-mathematical background student?

I am a PhD student in Mathematics working in Differential Geometry. As a part of my teaching assignment I need to explain the concepts of Limits and Continuity to some undergraduates majoring in Physics.

I don't know how to explain these concepts easily to them.Will anyone at all listen to me?

Should I make a slide presentation to them? Is it possible to explain mathematical concepts uing powerpoint/latex?

Are there any sites or online resources which can help me to make them understand Mathematics in an easier way?

• Get a good book. Follow it closely. They have likely spent more time considering this, testing, and refining than you have available. (Suggest OpenStax Calculus if none other available.) – Daniel R. Collins Mar 16 '18 at 12:30

• Slide presentations have turned out useful in my classes. The following slides on the limit are in German but should show the essentials. When looking at them please apply the animated screen representation of PowerPoint hs-augsburg.de/~mueckenh/Transfinity/M19.PPT – Wilhelm Mar 16 '18 at 13:06
• Don't confuse format with content. Whether the material is explained in a slide or formatted with LaTeX is probably much less important than what you say. – mweiss Mar 16 '18 at 21:00
• What kind of limits? Limits of functions of real numbers? Of sequences? – user7171 Mar 18 '18 at 14:59
