  1. Hi there. So today we're gonna talk about identifying figures.
  2. So we're gonna talk about the geometrical figures.
  3. Um We're gonna talk about polygons and we're gonna talk about quadrilaterals,
  4. which to me are the most important to understand.
  5. Um
  6. So let's start off talking about what are geometrical figures.
  7. So geometrical figures are closed shapes using points, line segments,
  8. circles and curves.
  9. So almost any figure that is closed or any shape, for example,
  10. that is closed is going to be a geometrical figure.
  11. Um
  12. There's some that you could
  13. somehow make up.
  14. Um But a lot of them just have to be closed in order to be that geometrical figure.
  15. So for example, we have our circle and that doesn't have any line segments.
  16. Um But it does have
  17. all the curves to it.
  18. Second, we're gonna talk about what is a polygon.
  19. So a polygon is a closed two dimensional figure created
  20. from three or more line segments with straight sides.
  21. So when it comes to polygons, we can't have any curves in our polygons,
  22. they have to have three or more.
  23. So for example, you see this equilateral triangle in the image to the side
  24. that
  25. has the um minimum amount of sides
  26. and it has all of its straight lines connecting together. So we have our
  27. triangle.
  28. Um we have our square which is a quadrilateral
  29. from the definition looking up on this picture,
  30. it says that they have sides of equal length in angles.
  31. So we all know that our square has all
  32. four equal sides with 90 degree angles within it.
  33. Our Pentagon again has equal sides. Um
  34. The two top ones are equal,
  35. the two side ones are equal and we know that it has all the angles.
  36. Um Lastly, we have our hexagon,
  37. those have all six sides of the same length and all angles of the same
  38. um
  39. degree.
  40. Perfect. So let's move on to what is a quadrilateral?
  41. So you guys have probably heard all of these different names at least,
  42. I hope you have.
  43. Um
  44. And a quadrilateral is a four sided figure
  45. which means there's four sides, four angles and four vertices
  46. over here.
  47. Our picture to the side, we have squares, rectangles, parallelograms,
  48. trapezoids, rhombus and kites.
  49. Um kites are very odd to see um which it is a shape and it is a quadrilateral.
  50. I just feel like we don't see it a lot within our word problems.
  51. Um So we see that each of these have four sides.
  52. Um
  53. Although the four sides, for example,
  54. on like the trapezoid are different angles as well as the kite.
  55. We do notice that they
  56. do have their four vertices in our four angles and four sides.
  57. So even though they're different
  58. lengths in their sides is not all equal, um that still makes it a quadrilateral.
  59. And as we see in here, we do have
  60. all geometrical figures. So they all are close shapes
  61. with points, line segments, circles and curves.
  62. Um Of course, of course,
  63. our quadrilaterals are not circles because they have to have four sides,
  64. four ankles and four vertices.
  65. But it does follow along with all the other rules for that. And we see that
  66. we do see a polygon within this with the square and um
  67. with the square having all the same size,
  68. um we do see the rectangle in the parallelogram are very similar.
  69. They just um
  70. have their different angles and their different side lengths.
  71. So moving on, we are going to talk about
  72. what am I? This is gonna be our activity that we are going to do.
  73. Um I'm gonna do it with you guys just to give you guys the short idea of it.
  74. And then if your teacher chooses to,
  75. she can actually do this within the class with you.
  76. So what am I is um
  77. this activity where we are going to have different cards
  78. and we're going to have them paired with the shape.
  79. And so we're gonna look at the um
  80. the rules or the clues that they give us and we're going to pair them up with a shape.
  81. So with the example that I have for you, they're all paired up.
  82. Um
  83. But what you will do in your class is we can
  84. have them cut and split and then you can go from there and make it the activity.
  85. So this is the example that I have. So
  86. we have a Pentagon, a hexagon, a rhombus, a square parallelogram,
  87. trapezoid triangle, octagon and a rectangle.
  88. So on one side, it's the shape and the other side,
  89. it's the clothes to match with the shape.
  90. So within your class, you can cut it right down the middle. Um
  91. And you can have the matching cards.
  92. It'd be really fun to have it for each group as they can um
  93. learn,
  94. learn the different clues and the different rules of
  95. each shape and combine them and pair them up.
  96. So for just a few examples, we have um a Pentagon.
  97. So I am not a quad
  98. quadrilateral. I'm a polygon with more than four sides, but less than six sides. So
  99. we can look at this and be like,
  100. OK, let's look at our rules for a polygon.
  101. If it's not a quadrilateral, we don't need to look at the quadrilateral rules.
  102. So looking at the polygon rules, we see that it has um
  103. we see that it's a closed figure
  104. and we see that there are three or more line segments with straight sides.
  105. So
  106. what is it?
  107. It's a polygon
  108. with the hexagon. We can, we, it tells us right away that it's a polygon. Um
  109. And it says it has twice as many sides as a triangle.
  110. So we think about that, we look at our rules and there we go,
  111. we know that it is a Hexagon.
  112. Um
  113. It's just the idea of learning their shapes and learning
  114. your rules for each shape so that you can identify
  115. um when it comes to a test or something and you're like, OK,
  116. what shape are they talking about?
  117. So this is a super fun activity. Um
  118. And yeah,
  119. I think it is great for memorizing your
  120. shapes and learning the different rules and aspects of
  121. um geometrical figures.
  122. Perfect. So lastly, there's a reflection.
  123. Um So two things you learned in this video and one question you still have.
  124. So for example,
  125. two things I have learned from teaching out this video
  126. is that there are a lot of fun activities to do
  127. um
  128. as students independently or with your class as a whole.
  129. Um There are a lot of amazing things to do
  130. to learn your shapes and the different rules and attributes of them.
  131. Um I also learned
  132. that I do not really know my shapes as well as I thought I did.
  133. Um I think I could do this activity and I think I could do pretty good on it,
  134. but I'm not sure how great I would do on it.
  135. Um And I don't have any questions as I am making this video for you. But
  136. let me know if you do have any questions and I'm excited to hear from you.
