What's My Ratio?
Students investigate ratios of various objects. In this ratios of various objects lesson, students draw pictures on graph paper and then dilate or shrink the image. Students determine the ratio of their pictures. ...
Curated OER
Patterns and Functions
Students investigate patterns and functions. In this algebra lesson plan, students examine the repetition of integers and objects. They create formulas for the repetition and identify them as function using equations.
Curated OER
Patterns
Students identify patterns in equations. In this algebra lesson, students write equations of problems with recurring patterns. They relate and model real life situation using functions.

Geometry in Tessellations
Students examine tessellations and their geometric properties. Students also develop a better understanding of lines, planes, angles, and polygons.
Curated OER
Geometry Scavenger Hunt
Pupils use the digital camera, identify geometric shapes (in nature as well as man-made), and gain a better understanding of geometric vocabulary. They search for and recognize geometric shapes in unusual settings
Education Development Center
Similar Triangles
Model geometric concepts through a hands-on approach. Learners apply similar triangle relationships to solve for an unknown side length. Before they find the solution, they describe the transformation to help identify corresponding sides.
