1. Desmos: So Much More Than Just Graphing
Jeff Parent
& Imad Dakka

2. Topics to cover - partial list!
You can shut off: Minor Grid lines, Major Grid lines, Axis
Can Graph in Polar
Numbers on the axis
Arrows on the axis
Make sliders for “constant” values
Projector Mode
Trig Scale
Tables
Piecewise functions
Graphing inequalities
Regressions
Insert Pictures
Insert Notes
Make multiple accounts, search for topics/sections.
Functions that are defined in terms of functions.
Summation notation
Enable Marble slides and Card sort
Google things you want to know, for instance “normal curve, desmos” or “Riemann Sum Demos” mzcu (Riemann Sum)

3. “Projector Mode” Without With

4. Step size and grid lines
Without steps or grid lines
With grid lines

5. Step size and grid lines
With steps large steps/ grid lines
With steps or grid lines

6. Arrows/trig steps - Type “Pi” to get the symbol:
No arrows and integer steps
Arrows and trig steps

7. Notes, labels, points.

8. Inserting: notes and pictures

9. Piecewise functions, inserting pictures, and notes

10. Piecewise functions - speed of sound
y={condition/range of x’s : equation , condition/range of x’s : equation}
y={0<x<11.5:-4x+11.5, 11.5<x<22:295,22<x<32,
32<x<50: 3x/ , blah, blah, blah….}

11. Piecewise functions - done simpler
Guilty Pleasures: not having to solve for y and graphing vertical line easily

12. Graphing linear inequalities

13. Inserting: Tables (max of 50 points)

14. Not your dad’s rootbeer regression

15. Not your dad’s rootbeer regression

16. Parameters
Adjust manually or set to play
Select “All”

17. Insert a .jpg

18. Adjust the parameters to fit.

19. Area in Polar Coordinates

20. Area in Polar Coordinates

21. Slope as an Approximation to the derivative

22. Slope as an Approximation to the derivative

23. Using a summation as a function

24. Using a summation as a function

25. Integrals and area, using the standard normal curve

26. Riemann Sums using desmos

27. Creating your 1st activity: teacher.desmos.com
Create an account on Desmos -they don’t spam!
Go to teacher.demos.com/labs and (while signed in) turn on “Marble slides” and “Card sorts”.
While signed in, click “custom”
Choose “Polygraph” or “New Activity”

28. Turn on Marble Slides and Card Sort !!!!!!
You must turn on Marble Slides and Card Sort to be able to use these features.
Go to:
teacher.desmos.com/labs
and check the boxes there.

29. Creating a Custom Activity: Polygraph

30. Create the Polygraphs

31. Polygraphs: Create a link or give students the code
Students will get a primer to help them understand the game. They can skip this primer once they know how to play.

32. Polygraphs - for pairs of students, Jeff and Imad

33. Polygraphs - Jeff’s view as the “Picker”

34. Polygraphs - Imad’s View as the guesser

35. Imad can eliminate graphs based on Jeff’s response

36. Polygraphs -eliminate all graphs but one!

37. Polygraphs - It took 4 questions, can you beat that?

38. A quick follow-up question before changing sides

39. Teacher View of the game

40. Creating a Custom Activity: Marbleslide (and more)

41. Creating a Custom Activity: Your Choices

42. Custom activities: What is a marbleslide?

43. What is a card sort?

44. What is a card sort?

45. Creating a Custom Activity: Graphs

46. Creating a Custom Activity: Sketch
You can use slides in combinations. Here, you can get student answers from “input” or “choices”.

47. Creating a Custom Activity: Multiple Choice

48. Multiple choice

49. Creating a Custom Activity: Multiple Choice
Multiple choice - have students give a reason for their answer!

50. Send your student to your activity!

Have an account for each course, save and title your work for instant recall later and/or sharing.
Have fun! Try things. Go to and look around!
