Poly-Yarns

Copernicus Education Gateway

 

Subject:

Mathematics

Grade:

 

 

9-12

 

 

ICLE Standards:

 

 

Math as Communication:  Reflect and clarify thinking about math ideas and relationships.

Geometry:  Represent polygons with modeling.

Interpersonal: Work collaboratively.

 

 

Performance Task:

 

 

Our class has been asked to review basic polygons with a group of younger students. In order to make the learning lively and engaging for younger students, we will coach the students as they follow these directions.

  • Younger students will be divided into groups of four to six members. Two of our class members will coach the younger students.

  • Each group will be given a piece of yarn 6 to 9 meters long.

  • Each group will require plenty of space to perform this activity.

  • The groups will be provided with the following rules:

  • All members must have both hands touching the yarn

  • Not all yarn needs to be used-extra yarn may hang.

  • Questions will be answered only if everyone in the group has the same question

  • Each group will model the following polygons and explain their model.

triangle    isosceles triangle
square    equilateral triangle
rectangle trapezoid
isosceles trapezoid   hexagon
20-sided polygon 2 congruent triangles
3 noncongruent triangles parallelogram, not a rhombus

Participate, sometimes leading, in group meetings by contributing, taking turns speaking, and working toward a common goal.  ELA.20
