What do students love more than building? Building with marshmallows! In this lesson, students get to build shapes with marshmallows and toothpicks. Included are an extensive lesson plan, a video showing examples, a worksheet, and ideas...

Lesson plans for students to learn the attributes of common 2D shapes. Lesson includes introduction, guided practice, and independent practice.

This task challenges a student to demonstrate understanding of the attributes of two-dimensional shapes.

Practice your 3D visualization skills by rotating 2D shapes.

I love graphic organizers. My students will increase their vocabularies by learning more 2D shape terms through the use of a graphic organizer.

A comprehensive guide for learning all about plane shapes with definitions, properties, types, solved examples, and practice questions.

Review the name of 2D shapes with this concentration game.

Second graders will be able to identify 2-dimensional shapes and tell the number of vertices and sides.

Analyze various shapes according to their reflective and rotational symmetries.

This lesson plan has students identify shapes by coloring the given shape a specific color.

Use this site to practice identifying shapes, colors, and animals with these interactive games.

Identifying 2D shapes in common objects and sorting according to shapes connects the real world to learning shape names and attributes.

Students will tell if a shape is 2-dimensional or 3-dimensional.

This interactive exercise focuses on discovering the relationships between two and three-dimensional shapes.

Demonstrates how to calculate the area of two-dimensional shapes using formulas. Covers parallelogram, triangle, trapezoid, and circle. Includes a video modeling how to find the area of a circle and a triangle. [0:59]

Students make a series of geometric drawings of points, obtuse angles, rays, polygons, and the like. Each child is given one but not allowed to show anyone else. The drawing is then taped to the back of the child in front of them. The...

Provides a list of area and perimeter formulas for two-dimensional shapes and volume and surface area formulas for three-dimensional solids.

Explore connections between a 2-dimensional net and a 3-dimensional box. Later in this section, use equations with variables to solve real world problems that use 2 and 3-dimensional objects.

In this video segment [3:25] from Cyberchase, a plant expert shows Bianca the patterns and symmetry found in nature.
