Transformations: Translations
Young scholars perform transformations and translations using polygons. In this geometry lesson plan, students perform transformations on a coordinate plane. They identify the image and pre-image of each figure.
Curated OER
Tessellations
Students identify and construct figures that tessellate. They investigate which regular polygons tessellate and how to modify them to make other tessellating figures. Students explore how naturally occurring tessellations have been...
Curated OER
Transformations: Reflections
Learners perform transformations on their graphs. For this algebra lesson, students identify the pre-image and image. They find and identify congruent shapes and isometry.
