Lines, Segments, and Rays

In this three-dimensional shapes geometry lesson, learners identify geometric solids and name their properties. They define "face," "edge," and "vertex," and construct geometric solids using marshmallows as vertices and toothpicks as edges.

For this math worksheet, students learn to measure common classroom objects or body parts using a standard inches ruler and a centimeter ruler. Students measure 21 objects in both ways.

Students enjoy making 3-D figures while learning about rectangular prisms, pyramids, vertices, edges, and faces. After a lecture/demo, students use marshmallows, toothpicks and a worksheet imbedded in this lesson to create 3 dimensional...

Fifth graders create designs that have lines of symmetry using pretzel and marshmallows. In this symmetry design lesson, 5th graders work in groups using graph paper, rulers, and toothpicks to plan their own lines of symmetry design....

Fourth and fifth graders investigate angles and name them according to the criteria for obtuse, acute, and right angles. They examine a human-made yarn pattern on the floor of their classroom and identify angles, vertices, and types of...

Fifth graders explore geometric building blocks in the real world in order to describe the characteristics and relationships of points, lines, line segments, rays, and planes. This is the first lesson plan in a series of lessons in...

Complete a number of activities in this group of lessons about dental health and teeth. Your elementary students will like the projects like making teeth models, reading a book, writing poetry and diagramming teeth.

Young scholars investigate geometric shapes. In this geometry lesson, students read the book The Greedy Triangle and define the shapes mentioned in the book. Young scholars make the shapes by using their bodies.

Fifth graders, after seeing Honeycomb examples, complete a Classifying Angles worksheet, Clock worksheet, and Defining Angles worksheet.

Fifth graders work with polygons.
