Terrific Tessellations

As a culminating project for our Shapes and Designs unit, Students worked in small groups of 2-4 to create a catalog of tessellations for a fictional flooring business.  Each student in a group was responsible for creating 2 tessellations for their group's catalog, as well as mathematical explanations as to why their shape or combination of shapes would tile a surface, accompanied by visual representations.  Click here to see the assignment sheet and grading rubric!

Here are some catalog covers....(Note some of the clever company names)









Below are some excerpts from various catalogs, including full page designs and explanations for why/how shapes create a tessellation. For a closer look, click on the picture.










As you can see, some students went into great detail in explaining their tessellations, including ways of finding angle sums, individual angle measures, and how/why they will tessellate.

Happy December!

To culminate the Shapes and Designs unit, students are working in groups on a project in which they work for a fictional company called Floored. Each team needs to create a catalog of  floor designs for a that can be made with various regular and irregular shapes.  Project Assignment Sheet and Grading Rubric

Below are a few pics of students working on some initial designs....


 






In addition to getting a start on this culminating project, students have been working on solving algebraic equations.  This mini-unit is much more procedural in nature than our core curriculum.  It involves learning steps in "balancing" equations and solving for unknown variables.  We start with manipulatives and visual images - pawns that represent "X" and scales that represent equations- and slowly ween away the visuals and manipulatives as students understand the concept and steps more abstractly. 
 Next week we will begin our new unit, Accentuate The Negative. Be sure to check back in a few weeks for pics from the students' floor design catalogs, as well as work we are doing in our new unit.
