In this nets and 3 dimensional figures instructional activity, 5th graders look at the 3D figure and the net and mark yes or no if it is an accurate representation.

Fourth graders explore geometry by utilizing pattern blocks. In this pattern lesson, 4th graders analyze two separate pattern block shapes and discuss which one is bigger and smaller. Students collaborate in small groups to create...

Fifth graders create mathematical creatures. In this geometry lesson, 5th graders create a creature from regular and irregular geometric shapes. Students review vocabulary and construct an original creature based on a rubric.

Students are introduced to polyhedrons through using straw models to explore geometric solids and constructing Christmas tree ornaments using Epsom salt crystals. Students will view interactive videos and investigate and retrieve...

Students follow directions to make a stained glass window design of regular and irregular polygons with specific geometric elements. In this geometry lesson plan, students also analyze other classmate's designs.

Students investigate basic geometric concepts. In this geometry lesson, students explore solids through measuring and modeling. This assignment models the importance of understanding concrete objects in geometry.      

Students explore geometry by creating jewelry in class. In this polygons lesson, students identify different shapes and characteristics while creating polygon figures from construction paper. Students utilize a multitude of shapes...

Students explore the concept of congruent triangles.  In this congruent triangles lesson, students use Cabri Jr. to construct two congruent triangles using circles.  Students determine if the two triangles are congruent by...

In this plane figure worksheet, students complete 4 multiple choice questions, determining which solid figure can be traced to make a given plane figure. A reference web site is given for additional activities.

In this geometry worksheet, 10th graders calculate the length of a chord and the distance from the center of a circle or radius. They compare diameter, chords and radius. There are 10 questions with an answer key.

Students make constructions and conjectures. In this geometry lesson, students construct right, acute and obtuse angles using a straight edge and a protractor. They investigate parallel lines and the angles formed by the angles.

Tenth graders define the formula for cylinders and use it to solve real world problems. In this geometry lesson, pupils differentiate between area, perimeters, 2D shapes, 3D shapes, and volume of prisms, cylinders and spheres. They...

Learners construct tangram pieces. Then they make observations and explore patterns with the pieces.

Third graders evaluate the attributes of cones. In this space shapes lesson plan, 3rd graders analyze three-dimensional shapes. Students explore the faces and edges of a cone.

Students identify and create shapes. In this geometric shapes instructional activity, students identify various polygons and try to create new shapes using existing polygons.

Students identify polygons. In this geometric shapes instructional activity, students identify and describe polygons. Students create new shapes out of the shapes they are given.

Students identify polygons and calculate perimeter. For this geometric shapes lesson, students complete a worksheet identifying various polygons and calculating the perimeter of triangles and quadrilaterals.

Students examine how to investigate polygons using an instrument of their own construction. They should be able to prove the general formula for the number of degrees in any polygon (including a triangle). Finally they investigate an...

Ninth graders investigate and describe ways that human understanding of Earth and space has depended on technological development. They describe and interpret the science of optical and radio telescopes, space probes and remote sensing...

Geometers explore the concept of tessellations. They use a tessellation applet to manipulate shapes and design their own tessellation using the applet.

Quadrilaterals can be quirky! Fourth graders use geoboards and bands to create four-sided figures. They analyze the attributes such as angle size and presence of parallel sides. As a result they learn to differentiate among...

In this geometry worksheet, students practice constructing a variety of graphs with various degrees of vertices. Students determine whether 12 graphs have an Euler circuit or path.

Students observe geometric relationships in buildings and structures. They reason why structures are constructed in a specific way by applying geometric concepts. They construct a shelter using their geometric knowledge.
