  1. Hey, boys and girls, Um, it's time for our quiz
  2. and just we need to get a piece of paper.
  3. What we're gonna do is give it a hamburger ful,
  4. check those corners to put my finger down and just
  5. increase it with my fingers.
  6. So I got this, and now I've got the hamburger
  7. full that undone the hamburger fold.
  8. Now I'm gonna do the hot dog folds right there.
  9. You but the corner.
  10. You put the paper in the corners on, then you
  11. find this.
  12. So we have 44 squares on our paper.
  13. Now we've got four, um, for, um, questions to answer.
  14. And I'm looking at we're gonna go a B c.
  15. So let's go ahead and label our our paper.
  16. I'm gonna get a one top corner, be in the
  17. other c nd and this will just help us keep
  18. our okay.
  19. It will help us to organize their information a little
  20. better. So I'm looking at a and yesterday we talked
  21. about subtracting all or subtracting zero.
  22. And there are Sam a recurring patterns when we subtract
  23. all. And when we subtract zero in a number, we
  24. talked about how when you subtract zero from a number,
  25. it always equals that number way also talked about.
  26. If we subject the number from the number, it always
  27. equals zero.
  28. So I'm gonna go ahead and do I'm a with
  29. you, and then you go ahead into B c and
  30. D. And when you're done to take a picture of
  31. your paper with your chromebook, and then you will, um,
  32. download it to Google Classroom so I can see your
  33. quiz. Thank you.
  34. All right, so we've got our paper looking at a
  35. way. We don't know the first number, but we're taking
  36. aways evil in an equals three.
  37. Well, I'm gonna think back about some of those rules
  38. or those recurring patterns that when I take zero from
  39. a number and always he closed at number.
  40. So when I take zero from a number, it always
  41. equals that number.
  42. Well equals three.
  43. So the number I'm taking zero away from must be
  44. three. So I'm gonna go ahead.
  45. And now when I show you this three, it's gonna
  46. probably be backwards.
  47. It isn It is backwards because of the video.
  48. Sorry about that.
  49. So let's see.
  50. So a equals three, and now we're going to move
  51. on 2 ft and thank of those, um, those rules
  52. with those re occurring patterns.
  53. When you take a on A when you when you
  54. take river from a number of equal set number on
  55. dhe, then if you take a and zero from a
  56. numbered always because that number and when you've see you
  57. might want to be thinking that if you take the
  58. number away from the number, you will always equal thing.
  59. Um, have fun with the quiz.
  60. And don't forget to send it to you so I
  61. can see how you well, you're doing You have a
  62. great day.
