Curated OER
Glide Reflections
Perform reflections and transformations by having your students create glide reflections from translated shapes. They use the TiNavigator to explore transformations.
Curated OER
Geometry: Tessellations
Students create tessellations with computer software while applying their knowledge of reflections, rotations, and translations.

Reflections
Fifth graders create a reflection of a poygon using a Mira. They discover that a line connecting a vertiex of a polygon and the corresponding vertex of its reflection is perpendicular to the line of reflection. Students create a glide...

Tantalizing Tangrams: What Are Transformations?
Students use the Internet to learn about transformations and tessellations. In this geometry lesson, students use the Internet to define the meaning of reflections, translations, rotations, glide reflection and symmetry. Students...

Investigate the Rigid Motions of Reflection, Rotation, Translation, and Dilation
Students investigate the rigid motions of reflection, rotation, translation, and dilation. This investigation be accomplished through classroom instruction and exploration using Geometer's Sketchpad.
Curated OER
Lines of Symmetry
Fourth graders demonstrate lines of symmetry using polygons, pentominoes, and block letters of the alphabet. They describe, identify, and analyze characteristics and properties of geometric shapes.

John Constable: artist
Students paint their own cloudy sky after studying paintings of the artist John Constable. In this John Constable lesson plan, students read and discuss the outdoor paintings of this artist and then complete their own painting of the...
