18. 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?

19. Guess My Rule Find Day 42, “Guess My Rule Shapes”
Quickly cut out the shapes
Watch as I model a game of Guess my Rule

20. Guess My Rule
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.
Think of two different characteristics of shapes. These characteristics will become your imaginary “rules”.
Place a few shapes in each side or the middle of the diagram according to your rules.
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.
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.
Don’t reveal your rules until all shapes have been sorted correctly!

21. Math Talk Let’s discuss the “sorts” you created today.
As you explain your sorts, use the math vocabulary we have discussed.
