Curated OER
Fun With Symmetry
Students manipulate shapes to find multiple lines of symmetry. They use color to visualize the lines of symmetry.
Curated OER
Are We the Same?
Students define and discuss symmetry, line of symmetry, and congruency. They cut shapes out of construction paper, identify the line of symmetry, and if they are symmetrical and/or congruent.
Curated OER
Transformation
In this transformation worksheet, learners identify and solve 10 different problems that include various images. First, they determine whether each object illustrated is a mirror image or reflection of the other image in the problem....
Curated OER
Quadratic Functions
Students graph quadratic equations on paper and check their results on the graphing calculator. They predict the direction of the graph and the vertex point. Students use the vertex, axis of symmetry and knowledge of which direction the...

Geo Jammin' By DeSign - Day 3, Lesson 13: Reflections
Students use current knowledge to predict the meaning of line of symmetry. They explore symmetry using mirrors.
Curated OER
Upside Down and All Around
Second graders discuss what a line of symmetry is, then demonstrate how to fold shape cutouts to generate lines of symmetry. They demonstrate slides, flips, and turns with objects, and write explanations of changes they observe in pictures.
