Students examine two- and three-dimensional shapes and figures. Individually, they practice identifying the shape from various viewpoints. By completing this activity, they develop a spatial sense about how figures and shapes are...

Try to figure out what happens with shadows as a person moves between two light sources. A formative assessment lesson has individuals work on an assessment task based on similar triangles, then groups them based on their...

Scholars see cross sections come to life using an app to investigate cross sections of three-dimensional solids. They look at prisms, pyramids, cylinders, cones, and double cones.

Learners use manipulatives to study shapes. They sort shapes and use correct geometric terminology to describe them. Students find real-life examples of 2 and 3 dimensional shapes, and classify figures in their classroom according to...

Aspiring astronauts construct a space vehicle using cylinders, cones, spheres, and rectangular prisms. This is an engaging method of learning about three-dimensional shapes. Note that the word cylinder is constantly misspelled in the...

First graders explore shapes. In this geometry instructional activity, 1st graders make shapes with geo-boards, use play-dough to make three-dimensional figures, and make a shape book using pre-cut shapes.

Students identify geometric solids.  In this shape lesson, students explore the characteristics of geometric solids.  They locate pictures of shapes on the internet, and identify the shapes.  Students draw pictures of...

Students create posters about geometric shapes in order to demonstrate their understanding of the different shapes. Students look for pictures in magazines to represent two-dimensional shapes, paste them on a poster, label the shape,...

Second graders draw a model using correctly formed geometric shapes. For this geometric shapes lesson, 2nd graders notice geometric shapes in the world around them and accurately draw these shapes.

Fifth graders use their arm, toothpicks, and marshmallows to create lines, segments, and rays. In this lines, segments, and rays lesson plan, 5th graders learn how these appear on a plane.

Just what does it take to show two rhombuses are similar? The assessment task asks pupils to develop an argument to show that given quadrilaterals are rhombuses. Class members also use their knowledge of similar triangles to show two...

Finalize the plans before playing in the sand. Learners design sandcastles using geometric and composite figures. They create blueprints, including the scale, and three-dimensional models of their castles. Finally, scholars calculate the...

Young scholars create a scale model to a castle using the dimensions they were given. They calculate the surface areas and volumes of each section of their castle.

Sstudents explore and analyze the properties of geometric areas.  In this geometry lesson, sstudents use technology to simulate spinners and dartboards in order to fing areas of circles and sectors of circles and compare and...

Fifth graders use estimation to solve word problems. In this fractions instructional activity, 5th graders decide whether or not an answer to a work problem is reasonable by applying their knowledge of fractions, decimals and estimation....

Students use problem solving skills to create various models of tricubes, tetracubes, and pentacubes. They classify the cubes into various groupings and identify them as mirror images, regular arrangements, and irregular arrangements....

Tenth graders have been introduced to the concepts of translation, reflection, and rotation, and have practiced translating, reflecting, and rotating two-dimensional objects on the coordinate plane.

Students take an Internet field trip to research fractions. ESOL strategies include using pattern block manipulatives and pairing ESOL and non-ESOL students on computers.

Fourth graders find the volume of solids. In groups, 4th graders use spinners to determine the dimensions of solids. They construct the shapes, creating a model of the figure Students count the cubes in the model to determine the...

Students describe, draw, and classify shapes. They use the internet to research the X-36 aircraft. Students identify the geometric shapes in the aircraft. They calculate the number of sides in an x-36.

Pupils construct geometric figures using Cabri Jr. in this constructing geometric figures using Cabri Jr. lesson. They familiarize themselves with Cabri Jr. and construct segments and triangles. Your learners will use various tools to...

First graders explore eight geometry activities that improve understanding of positional words and shapes. They identify, describe, and create simple geometric figures. They help another student who may not understand the concept yet.

Students explore differents types of triangles and quadriaterals. For this polygon lesson, students  model identify and compare two and three dimensional geometric figures. Students create tangrams and discover the difference...

Students explore the relationships among the lengths, areas, and volumes of similar solids. They also discover what effect doubling the dimensions of a figure has on the resulting area.
