Guess My Rule Alignment Lesson Day 42

Let’s Review Triangles The Triangle Song

Perpendicular lines Parallel lines intersect or meet to form right angles always are the same distance apart and never touch Recommendations You can make any necessary changes to the ppt to meet the specific needs of your students Preview in presentation mode prior to using in your teaching– there is a lot animation! Teacher Edition: p.377-378 Miscellaneous Notes: After perpendicular and parallel show up ask students what they know about each. Have them turn and talk to a partner. Then click to see what is in the boxes and the examples below. Can be used to do a quick review as you see fit: either it will link prior learning to new content today or it will build background

Angles greater than 90 degrees ( >90°) 90 degrees (90°) Recommendations You can make any necessary changes to the ppt to meet the specific needs of your students Preview in presentation mode prior to using in your teaching– there is a lot animation!

Equilateral triangle Isosceles triangle Recommendations You can make any necessary changes to the ppt to meet the specific needs of your students Preview in presentation mode prior to using in your teaching– there is a lot animation! Teacher Edition: p.377-378 Miscellaneous Notes: Can be used to do a quick review as you see fit: either it will link prior learning to new content today or it will build background An equilateral triangle has all congruent sides An isosceles triangle has all at least two congruent sides

Vocabulary Review Quadrilateral - a polygon with four sides

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

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

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

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

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

Vocabulary Review Pentagon - a polygon with five sides

Vocabulary Review Hexagon - a polygon with six sides

Vocabulary Review Octagon – a polygon with eight sides

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

What are ways to classify triangles? Classify by the length of their sides Scalene Isosceles Equilateral Classify by the measure of the angles Acute Right Obtuse

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

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!

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

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!

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