ExplorA-Pond:3rd Grade Shapes & Fractions
Students, using a map, drawing or aerial view of a pond, represent the shape of the pond using simple geometric shapes or fractions of those shapes. They identify the numerator and denominator in each fraction created.
Futures Channel
Folding Circles
Students investigate properties of circles. In this geometry lesson, students differentiate between similarity and congruence as they observe polygons. They investigate properties of two and three dimensional shape.
Curated OER
Folding Shapes; Are the Sides the Same?
Second graders explore geometry by experimenting with fold-ables. In this geometric shapes lesson, 2nd graders utilize cutout shapes from construction paper which they experiment with by folding. Students examine the symmetry and...

Polygons in Symmetry: Animal Inventions
Fourth graders use polygons to create animal figures with symmetry. In this polygons and symmetry lesson, 4th graders create a symmetrical animal collage by cutting and gluing geometric shapes and figures from math activities.
Curated OER
Box Folding: Predict, Analyze and Measure
Students predict the shape of a geometric figure in 3D. In this geometry lesson, students construct 3D shapes to perfect their knowledge of measuring and predicting. This assignment is also available as an online interactive lesson.

Classifying Polygons
Students study polygons. In this math lesson, students play a game in which they learn the classification system for polygons. Students identify the properties of quadrilaterals.
Curated OER
Fractal and the Dragon Curve
Students explore Fractal designs. In this geometry lesson plan, students observe the different polygons created in nature and relate it to math. They define polygons on planes and rotate polygons about a point.
Curated OER
Transformations Using the Geometer's Sketchpad
Students discover rules for single transformations, rules for composition of transformations, when a figure has transformation symmetry, and if a transformation is congruent to its preimage.
Curated OER
Symmetry with Manipulatives
First graders investigate symmetry in patterns by utilizing unifix cubes. In this pattern lesson, 1st graders practice creating patterns that are perfectly symmetrical no matter which way it's looked at. Students utilize...
