1. Fun with Angles and Polygons A unit for learning about geometry Ms. Collette Robitaille

2. Introduction to Geometry Unit 1: Angles (2 days) Unit 2: Triangles (2 days) Unit 3: Quadrilaterals (2 days) Geometry Webquest (5 days) Review Activities (3 days) Test (1 day) *This is a 3 week unit of instruction.

3. Unit One: Exploring Angles Can you name the following angles? Click on the angle to reveal its name. obtuse acute rightstraight

4. Angle Information Acute Angles – measure less than 90º Right Angles – measure exactly 90º Obtuse Angles – measure more than 90º but less than 180º Straight Angles – measure exactly 180º

5. Can you think of a way to remember the names for each angle?

6. Angles Task Activity For this activity, you will be paired up with a partner to visit the following website. After clicking below, skip the intro and click on the Make the Angle Game. You and your partner must make 10 angles and record them on a sheet of paper. Once you have recorded 10 angles, tell what type of angle it is. http://www.amblesideprimary.com/ambleweb/mentalmaths/protractor.html

7. Unit One: Angles Quick Check Question #1 An acute angle is greater than 90º. A.TrueTrue B.FalseFalse

8. Unit One: Angles OOPS!!!!! Remember an acute angle is a cute little angle. Try Again

9. Unit One: Angles Congratulations!!!!! An acute angle is less than 90º.

10. Unit One: Angles Quick Check Question #2 An obtuse angle is greater than 90º but less than 180º. A.TrueTrue B.FalseFalse

11. Unit One: Angles Quick Check OOPS!!!!! Better check again. Obtuse angles are almost right and not quite straight. Try Again

12. Unit One: Angles Quick Check Congratulations!!!! An obtuse angle is between 90ºand 180º.

13. Unit One: Angles Quick Check Question # 3 A straight angle measures 180º. A.TrueTrue B.FalseFalse

14. Unit One: Angles Quick Check OOPS!!!!! Remember. A straight angle looks like a straight line. Try Again

15. Unit One: Angles Quick Check Congratulations!!!! A straight angle measures 180º and looks like a straight line.

16. Unit One: Angles Quick Check Question #4 A right angle does not measure 90º. A.TrueTrue B.FalseFalse

17. Unit One: Angles Quick Check OOPS!!!!! A right angle looks like the corner of a piece of paper. Try Again

18. Unit One: Angles Quick Check Congratulations!!!! A right angle does measure exactly 90º.

19. Unit Two : Triangles Can you identify theses triangles by their angles? Right acuteobtuse Click on the angle to check your answer.

20. Unit Two: Triangles Right Triangles - have exactly one right angle. Acute Triangles – all angles are less than 90º. Obtuse Triangles - have exactly one angle greater than 90º.

21. Unit Two: Triangles Can you identify these triangles by their sides? isoscelesscaleneequilateral Click on the triangle to check your answer.

22. Unit Two: Triangles Isosceles Triangles - two sides are of equal length Scalene Triangles - no sides are equal in length Equilateral Triangles - all sides are of equal length

23. Triangles Task For this task, you and your partner, must complete the activity on the webpage listed below. Review the triangles and then click Triangles Quiz. Write your answers on a sheet of paper. Triangles Review

24. Unit Three: Quadrilaterals Can you identify the following quadrilaterals? parallelogramrectangle square rhombus trapezoid Click on the quadrilateral to check your answer.

25. Unit Three: Quadrilaterals Parallelograms - 4-sided figure, opposite sides are parallel and congruent Rectangle – 4 sided figure with 4 right angles and opposite side congruent Square – 4 sided figure with 4 right angles and 4 congruent sides Rhombus – 4 sided figure, all sides are congruent Trapezoid – 4 sided figure with one pair of parallel lines

26. Quadrilaterals Task For this task, you and your partner should visit the following website. Using the virtual geoboard you and your partner will need to construct each of the five quadrilaterals we have discussed. To complete the assignment, on a sheet of paper, tell how many geobands were needed to create each quadrilateral. http://matti.usu.edu/nlvm/nav/frames_asid_129_g_3_t_3.html

27. Unit Three: Quadrilaterals Quick Check Question #1 A rectangle is a four sided figure with 4 congruent sides. A.TrueTrue B.FalseFalse

28. Unit Three: Quadrilaterals OOPS!!!!!!!! Think about it. A rectangle looks like a long box. Try Again

29. Unit Three: Quadrilaterals Great!!!!!!!!! You remembered that a rectangle has 2 parallel sides, 4 right angles, and opposite sides are congruent.

30. Unit Three: Quadrilaterals Quick Check Question #2 A rhombus has four congruent sides. A.TrueTrue B.FalseFalse

31. Unit Three: Quadrilaterals OOPS!!!!!!!! Remember that a rhombus looks like a kite or a diamond. Try Again

32. Unit Three: Quadrilaterals HOORAY!!!!!! You remembered that a rhombus looks like an italic square and all 4 sides are congruent.

33. Unit Three: Quadrilaterals Quick Check Question #3 A square is a quadrilateral with only two right angles. A.TrueTrue B.FalseFalse

34. Unit Three: Quadrilaterals OOPS!!!!!!!!! A square has all sides congruent and all angles congruent. Try Again

35. Unit Three: Quadrilaterals Nice Job!!!!!!! You knew that a square has four equal sides and four equal angles.

36. Unit Three: Quadrilaterals Quick Check Question #4 A trapezoid is a four sided figure with one set of parallel sides. A.TrueTrue B.FalseFalse

37. Unit Three: Quadrilaterals OOPS!!!!!! Think of the tables in a classroom. It looks like a triangle without the top. Try Again

38. Unit Three: Quadrilaterals AWESOME!!!!!!! A trapezoid has exactly one set of parallel sides.

39. Unit Three: Quadrilaterals Quick Check Question #5 A parallelogram has two sides that are parallel and opposite angles are congruent. A.TrueTrue B.FalseFalse

40. Unit Three: Quadrilaterals OOPS!!!!!! Remember that a parallelogram looks like an italic rectangle. Try Again

41. Unit Three: Quadrilaterals Nice Work!!!!! A parallelogram is a 4 sided figure with opposite sides parallel and opposite angles congruent.

42. Unit Four: Geometry Web Quest

43. For this part of the unit I would like for you and your partner to explore geometry using the internet. There are two web quests listed below. Follow the directions for each and turn in your completed project. Have fun!!! Web Quest #1 Web Quest #2
