Terrific Tessellations
Students explore tessellations that are found in nature and everyday objects. They observe the works of M.C. Escher. Students create their own tessellations using pencil and paper.
Curated OER
Visual Patterns in Tessellations
Students explore tessellations as well as various types of polygon. Students examine tessellating patterns in the world around them. Students examine tessellations by creating their own tessellations and completing the included worksheet.

Introduction to Fractals: Infinity, Self-Similarity and Recursion
Students think about several of the concepts from fractals, including recursion and self similarity. They use mathematical concepts of line segments, perimeter, area and infinity are used, and skill at pattern recognition is practiced.
Curated OER
Slope Right Up
Students use triangles to find the length and slope of each side. After connecting the vertices, they add points based on their specific instructions. They use the Pythagorean Theorem to complete a worksheet to end the lesson.

Geo Jammin By Design: Coordinated
Students watch the teacher draw on the chalkboard and try to determine the form being drawn. They use questions to determine Quadrant #1 of a coordinate plane.
Curated OER
Building Paper Bridges
Students construct a bridge that can hold 100 pennies. In this math lesson plan, students evaluate the strength of their bridges. They predict how much weight a bridge can hold based on its design.
Curated OER
Odd Thing Out
Students listen to the math problem provided and work in groups to solve. They think about the objects and write down their information in a table. Class construct the table on a large piece of paper that can be put on the wall after the...
