Students compare and contrast angles and identify them as acute, obtuse, right, or straight angles. They create rays and angles using uncooked spaghetti, read and discuss key vocabulary terms, and complete a variety of geometry worksheets.

Third graders engage in a instructional activity that focuses on the attributes and forming of a cube. They construct a cube using different combinations while comparing a square with only two-dimensions. Students fold paper while...

Tenth graders explore congruent triangles.  In this geometry lesson, 10th graders investigate the conditions necessary to prove two triangles congruent.  The lesson combines dry erase board activities and the use of technology.

Students investigate nets as they relate to volume and area. In this geometry lesson plan, students use nets as a visual to deepen their understanding of surface area and volume of objects. They make conjectures about different objects...

Students, in groups, determine the volume of a box large enough to hold a million dollars. They calculate the dimensions of a bill and the volume of the money.

Second graders practice unit fractions to identify parts of the whole and parts of a set. They utilize a variety of manipulative's including recipe boxes to get them started stirring up fractions. A multitude of books on fractions are...

In this water on planetary surfaces learning exercise, learners read about the Galileo spacecraft and the surface of Jupiter's moon Europa. They read about the energy needed to keep the water in a liquid state on Europa. Students solve 4...

In this power-law functions learning exercise, students solve 3 problems using data from the Wide-field Infrared Survey Experiment in the constellation Carina. Students use a photograph to determine the number of stars as bright as the...

Students explore crystals through the story Snowflake Bentley and then create crystal pictures of their own. In this interdisciplinary lesson, they create a crystal web chart on chart paper, design artificial snowflakes, and write poems...

Whatever floats your boat. Young engineers learn about density by measuring the masses and volumes of boxes filled with different materials. Using their knowledge of densities, they hypothesize whether objects with given densities will...

Participate in three activities that look at the earth's limited water supply and the changes water goes through as it enters each phase of the water cycle. The resource is complete with three activities that demonstrate the changing...

A set of first grade geology lessons focuses on plate tectonics and movement of plate boundaries. During the pre-lab, learners experience three types of plate movement through a kinesthetic demonstration. The lab...

Take young geologists on an exploration of the rock cycle with this six-lesson earth science unit on rocks and minerals. Through a series of discussions, demonstrations, and hands-on investigations your class will learn...

Students explore the concept of density. In this density lesson plan, students determine the density of a crown and a sample of clay. They hypothesize about the densities of 4 liquids they are given including molasses, cooking oil, a red...

Students experiment to see how various objects roll down ramps. In this ramp lesson, students observe weight, size, and material of objects.  Students compare speeds by using a second ramp.  

Meet Morisu in the dojo. Help him with symmetrical objects and shapes!

In this lesson plan on solid shapes, students will learn to identify three-dimensional shapes by their attributes and learn to recognize them in the real world.

In this lesson, students will identify 2- and 3-dimensional shapes as well as create shape drawings and sculptures. Teacher materials are available.

In this lesson, students will create a shape mobile of 2-dimensional and 3-dimensional shapes made from geometric shapes.

Investigate the concepts of area, volume, 3D shapes, and nets using this interactive Learn Alberta math. The solid shapes focused on this exploration include rectangular and triangular prisms, rectangular and triangular pyramids,...
