SMART Notebook 8.0Oct 28 - 11:48 AMTeacher Notes Subject: Numeracy Topic: Geometry Title: Introduction to Tessellation Age(s): 10-11 years Curriculum Related Themes: Lesson Objectives: 1) To identify polygons 2) To understand what tessellation is3) To learn two ways to tessellate polygons SMART Board(TM) interactive whiteboard features incorporated:1) Writing with a stylus2) Moving objects with finger Recommended Usage: Introduction - group workOct 28 - 11:46 AM Operating System: Windows(R) and Mac OS XSubmitted by: Candace BeatonIntroduction to TessellationOct 27 - 11:40 AMWhat is a polygon?Circle the polygons below:A polygon is a closed figure formed by three or more line segments that do not cross.Move box to reveal answer.Oct 27 - 2:41 PMTiling with PolygonsSome polygons can be used to tile a surface. When you tile, it is important not to overlap tiles or leave gaps between tiles. Tile the large rectangle below by dragging the tiles into place.Oct 27 - 2:51 PMWhy won't these shapes tile properly? What does this teach you about tiling? Tile the following rectangle using the tiles provided.Tile the following rectangle using the tiles provided.Oct 27 - 3:03 PMPredict which shapes will tile and which will not. Oct 27 - 3:16 PMWhat is a tessellation?A tessellation is a repeated geometric design that covers a plane without gaps or overlaps -- in other words, it's just tiling!Now that you know what tessellation is, use the polygons on the following pages to create tessellated patterns .Move box to reveal answer.Oct 27 - 3:36 PMUse the polygons to create a tessellated pattern.Oct 27 - 3:41 PMUse the polygons to create a tessellated pattern.Oct 27 - 3:42 PMHINT: Rotate some of the polygons to create this tessellation. ExampleUse the polygons to create a tessellated pattern.Nov 20 - 11:11 AMHINT: Rotate some of the polygons to create this tessellation. ExampleUse the polygons to create a tessellated pattern.Oct 28 - 9:55 AMUse the polygons to create a tessellated pattern.Oct 28 - 10:28 AMTessellating a shape across a surface, without flipping it or changing the position of the corners.124123412341234There are two ways to tessellate objects:This example was created using slide translation. 3What is slide translation?1. Manipulating polygons so they fit together (as you have been doing).2. Using slide translation.Move box to reveal answer.Oct 28 - 1:05 PMLook around your classroom, school and community. Can you find examples of tessellations?
