Tessellations *Regular polygon: all sides are the same length (equilateral) and all angles have the same measure (equiangular)

G Stevenson What Are Tessellations? Basically, a tessellation is a way to tile a floor (that goes on forever) with shapes so that there is no overlapping.

Homework Review

Mental Math Please take out your Fact Triangles. Spend the next 5 minutes practicing your Fact Triangles and sorting them. Once you’ve sorted, focus on your TRY AGAIN pile. When you are finished, fasten the pile with paper clips and store them until our next practice session.

Math Message Take your baggie of straws and twist-ties. Make a shape with 5 sides.

Work in your groups to create polygons with 6 straws, 7 straws or 9 straws. What are the names of these polygons?

Convex and Concave (nonconvex) A polygon in which all vertices are pushed outward is called a convex polygon. A polygon in which at least one vertex is pushed inward is called a conCAVE polygon. At least one side CAVES in.

Math Journal practice

A polygon is a regular polygon if: -all of the sides have the same length -all of the angles are the same size -the polygon is convex An equilateral triangle is a regular triangle – it has three equal sides and three equal angles.

Math Boxes- Tonight’s hw.

Closure What did you learn about polygons today? Describe at least 3 facts.

What is a pentomino? A pentomino is a shape that is formed with 5 square tiles arranged in such a way that full sides touch full sides and all 5 tiles are flat and can be seen. There is no overlapping. **A pentomino is not considered different if it can be turned, flipped, or slid onto another pentomino to form the same shape and size.** Congruent shapes are the same size and shape.
