Now skip count to 70 by 7. And for a challenge, let’s alternate between numbers and units of 7. Start with units of 7 And now alternate starting with numbers.
Classify the Polygon How many sides does this polygon have? Polygons with four sides are called: How many sets of parallel lines does this quadrilateral have? Quadrilaterals with one set of parallel lines are called:
Classify the Polygon Is this polygon a quadrilateral? How many right angles does this particular quadrilateral have? Is this quadrilateral a trapezoid? Why?
Classify the Polygon How many sets of parallel lines does it have? What do we call all quadrilaterals that have two sets of parallel sides?
Classify the Polygon Is this polygon a quadrilateral? How many right angles does this quadrilateral have?
Classify the Polygon Is this polygon a trapezoid? Why?
Classify the Polygon Is this trapezoid also a parallelogram? Why?
Classify the Polygon Is this parallelogram also a rectangle? Why?
Classify the Polygon Is this polygon a quadrilateral? ☐ Is this polygon a trapezoid? ☐ Is this polygon a parallelogram? ☐ Is this polygon a rectangle? ☐ Does this polygon have 4 sides of the same length? ☐ ✔ ✔ ✔ ✔ ✔
Application Problem Frankie says that all squares are rectangles, but not all rectangles are squares. Do you agree with this statement? Why or why not? Draw diagrams to support your statement. Has 4 sides Has 2 sets of parallel lines Sides don’t have to be the same lengths. Has 4 sides Has 2 sets of parallel lines Sides are the same lengths.
Concept Development Analyze this shape. List as many of its attributes as you can. Quadrilateral. One set of parallel lines. No right angles. Two angles greater than a right angle. Two angles smaller than a right angle.
Polygon Game We are going to play a game. I will project a game board with three columns. Each column has an attribute: Angle type, polygon type, side type. We will reveal three attributes, and you will draw a polygon that has those attributes.
