1. Two Dimensional Shapes3rd Grade South Carolina Standards addressed 3-4.2 Classify polygons as either triangles, quadrilaterals, pentagons, hexagons, or octagons according to the number of their sides. 3-4.3 Classify lines and line segments as either parallel, perpendicular or intersecting 3-4.4 Classify angles as either right, acute, or obtuse 3-4.6 Exemplify points, lines, line segments, rays, and angles.

2. Do you know what each of these symbols represents? Amber Traverse Move to the next slide to learn the vocabulary that goes along with each of these symbols.

5. is part of a line

6. has two end pointsAmber Traverse For example, think about when we line up for recess. Each person is a point on the line. Student A and student B make a line segment. That part of the line begins at A and ends at B. A B C D E F G

8. continues in both directions

9. does not endAmber Traverse Take the motion of a ball. You push the ball, if there was no gravity that ball would continue on the path for an undetermined amount of time.

11. is part of a line

12. has one end point

13. continues on in one without endingAmber Traverse Pretend that you are in space and throw a ball from point A. Because there is no gravity that ball will continue in the direction thrown. A

14. Test your vocabulary knowledge Amber Traverse On your whiteboard/paper write the correct vocabulary word for each symbol. 1. 2. 3. 4.

17. Types of lines Amber Traverse Parallel lines arelines that never touch. An example of these lines would be the roads that we drive on. Perpendicular lines are lines that cross over each other. Where the two lines meet right angles are formed. For example, where two roads meet at a light and cross over each other. Intersecting lines are Lines that cross over each other. Where the two lines meet acute and Obtuse angles are formed.

18. Test your angle and line knowledgeAnswer each number by naming the angle or line represented on your paper/whiteboard. Amber Traverse 1. 2. 3. 6. 4. 5.

20. contain straight sides (no curves)

22. have exactly four anglesWhich of the following figures is not a quadrilateral?

24. have exactly three angles

25. can be named either by their angles, sides, or bothWhich of the following is not a triangle? Amber Traverse

29. Have exactly six anglespentagon octagon Amber Traverse

30. Polygon MasterpieceLook at the below picture made up of polygons; say the color then the name of the polygon. Amber Traverse
