3-5, 6-8
Use this applet to create patterns to cover the screen using regular polygons.
Pre-K-2, 3-5, 6-8, 9-12
Need a pentagonal pyramid that's six inches tall? Or a number line that goes from ‑18 to 32 by 5's? You can create all those things and more! Place the images you want, then export it as a PDF or as a JPG image.
3-5
In this
lesson students will develop a definition for tessellations. They will
also analyze the importance of the tessellated game board in playing and
winning the game NeXtu on the Calculation Nation website.
6-8
In this lesson, students explore regular and semi-regular tessellations. Students use manipulatives to discover which regular polygons will tessellate and which will not. Students will use geometry and measurement to investigate the three regular and eight semi-regular tessellations.
6-8
Students discover and explore a special kind of tiling of the plane. Rep‑tiles are geometric figures such that
n copies can fit together to form a larger, similar figure. Students experiment with various shapes and values of
n.
Spatial sense is encouraged by the need to visualize and perform
transformations with the shapes involved. This lesson was adapted from
an article by Linda Fosnaugh and Marvin Harrell, which appeared in the
January‑February 1996 edition of
Mathematics Teaching in the Middle School.
