1. Warm Up Jarod and Wake were building a castle using blocks. They began discussing the parallel sides on each of their quadrilaterals. Jarod said that all of the shapes had 2 sets of parallel sides. Wade told him that he was wrong. Who is correct? Explain why.

2. Guess My Rule Alignment Lesson

3. Let’s Review Triangles The Triangle Song

4. intersect or meet to form right angles always are the same distance apart and never touch Perpendicular linesParallel lines

5. 90 degrees (90°) Angles greater than 90 degrees ( >90°) Angles less than 90 degrees (< 90°)

6. Equilateral triangle Isosceles triangle An equilateral triangle has all congruent sides An isosceles triangle has all at least two congruent sides

7. Vocabulary Review Quadrilateral - a polygon with four sides

8. Vocabulary Review Parallelogram - a polygon with two pairs of parallel sides A rectangle is a parallelogram A rhombus is a parallelogram A square is a parallelogram

9. Vocabulary Review Square - a parallelogram with all sides the same length and all right angles – Diagonals are congruent – Diagonals are perpendicular – A quadrilateral

10. Vocabulary Review Rectangle - a parallelogram with all right angles – Diagonals are congruent – Opposite sides are congruent

11. Vocabulary Review Rhombus - a parallelogram with all sides the same length Diagonals are NOT congruent Diagonals are perpendicular

12. Vocabulary Review Trapezoid – a quadrilateral with ONLY one pair of parallel sides Right trapezoid - a trapezoid with right angles

13. Vocabulary Review Pentagon - a polygon with five sides

14. Vocabulary Review Hexagon - a polygon with six sides

15. Vocabulary Review Octagon – a polygon with eight sides

16. Vocabulary Review Kite - A quadrilateral with two distinct pairs of congruent, adjacent sides and diagonals that intersect at a right angle.

17. What are ways to classify triangles? Triangles Classify by the length of their sides ScaleneIsoscelesEquilateral Classify by the measure of the angles AcuteRightObtuse

18. Which types of quadrilaterals can be classified as parallelograms? Square Rectangle Rhombus

19. Is a trapezoid a parallelogram? Why or why not? NO!!! A trapezoid is not a parallelogram because it only has ONE PAIR of PARALLEL SIDES! What are the characteristics of a regular polygon? All angles are congruent! All sides are congruent!

20. Guess My Rule Find Day 42, “Guess My Rule Shapes” Quickly cut out the shapes. You don’t have to cut on each line. Just cut around the shapes. On your white boards, draw a T chart. Mark one side as “Yes” and the other side as “No”

21. Characteristics of Shapes I’m going to give you some characteristics and you must move 4-5 shapes under the “Yes” and “No” columns depending on whether or not it fits that characteristic. 1 st characteristic – opposite sides parallel Share the shape numbers/names you put under the “Yes” column. Give viable arguments to prove your case! What about the “No” column??

22. Continue with More Shape Characteristics (move on chart according to each characteristic) Opposite sides congruent At least one obtuse angle At least one right angle All sides congruent All angles congruent Two consecutive sides congruent Parallelogram Regular polygon Opposite Angles Congruent Has 4 sides Isosceles

23. Materials Needed for Game Your shapes you just cut out Grouping circles or Day 42, “Venn Sorting Hoops” We will go over instructions of the game and then I will model it for you!

24. Guess My Rule Game Instructions Purpose: Your goal is to have your partner guess your “rules” by naming shape numbers that fit into each side (or the middle) of a Venn diagram. 1.Think of two different characteristics of shapes. These characteristics will become your imaginary “rules”. 2.Place a few shapes in each side or the middle of the diagram according to your rules. 3.Keep adding shapes on the diagram until your partner thinks he/she is ready to try and place a shape him/herself correctly in the diagram. 4.If your partner thinks he/she knows the rule, prove it only by naming a shape that fits the rule and not by telling the rule. 5.Don’t reveal your rules until all shapes have been sorted correctly!
