Symmetries II: Conclusions: In this lesson, one of a multi-part unit from Illuminations, students reflect on what they learned in the three previous lessons. (Learn more); Format: lesson plan (grade 9–12 Mathematics); Provided by: National Council of Teachers of Mathematics

Symmetries I: Conclusions: This lesson challenges students to reflect on the mathematical ideas learned in a multi-part lesson on Geometry. (Learn more); Format: lesson plan (grade 9 Mathematics); Provided by: National Council of Teachers of Mathematics

Relationships between reflections and symmetry: In this lesson, one of a multi-part unit from Illuminations, students learn the properties of designs that have bilateral symmetry. They also make their own designs and investigate dihedral symmetry. (Learn more); Format: lesson plan (grade 9–12 Mathematics); Provided by: National Council of Teachers of Mathematics

Reflect on this: In this lesson, from Illuminations, students investigate reflections in a plane using mirrors (or other reflective materials) and a geometry utility. They apply their findings to examination of interior angles of regular polygons. (Learn more); Format: lesson plan (grade 9–12 Mathematics); Provided by: National Council of Teachers of Mathematics

Exploring measurement, sequences, and curves with stringed instruments: In this lesson, one of a multi-part unit from Illuminations, students measure lengths on stringed musical instruments. They discuss how the placement of frets on a fretted instrument is determined by a geometric sequence.

Describing reflections: In this lesson, one of a multi-part unit from Illuminations, students learn how reflections work and what happens when two or more reflections are applied one after the other.
