#Pattern blocks pdfYou can watch me making the presentation in a condensed 90-minute video version of a three-hour workshop here And here is a K-8 version of the talk: PDF | Keynote. The Keynote version features some fun animations. This presentation ( PDF | Keynote) is mostly about pattern blocks, but it does include some work using the Geometry Labs template. If you create more pattern block wallpaper starters, I will post them here and credit you. The idea is to extend the given pattern, using the given mirror lines as the only guide. Wallpaper Starters is a challenging puzzle-like activity which combines symmetry and tiling. I made a catalog of those, illustrating each one with an example using pattern blocks. Wallpapers Catalog: From the point of view of symmetry, there are exactly 17 different wallpaper designs. This provides a great context to discuss symmetry (see Geometry Labs 5.6.) An extension: cover the 2-inch-side big dodecagon with pattern blocks: examples, activity, and discussion. (This an online applet for Geometry Labs 5.6)ĭodecagons:A classic activity is to cover a 1-inch-side dodecagon with pattern blocks. Symmetry with Pattern Blocks: cover a regular triangle, hexagon, and dodecagon with pattern blocks, and analyze the symmetries. In fact, they are used in the first and the last lesson in the book! Here is an index of the labs that use pattern blocks: Angles: 1.1, 1.2, 1.4 Polygons: 3.3, 3.6 Symmetry: 5.4, 5.6 Tiling: 7.2 Measurement: 9.5, 11.8 Similarity: 10.4Īlong with much else, my Symmetry home page includes pattern block links, including these three: (And yes, they're fun!) On This Site Pattern blocks are featured in my book Geometry Labs, a free download on this site. Yet, they do offer plenty of interesting curricular opportunities. Pattern blocks are ubiquitous in elementary schools, but they're not commonly seen in middle school or high school. Manipulatives Pattern Blocks in middle school and high school
