Students recognize that quilts are created by geometric components. They examine how quilts are an artistic art form that show the cultural heritage of the people who make them.

Does the mention of proteins and polypeptide relationships in your classroom result in mass confusion? Does the attempt to teach this important concept generate multiple questions and, at times, lead to a room filled with blank...

Students listen to the poem "Shapes" by Shel Silverstein in order to accurately and specifically describe shapes' rules/traits in their journals. They illustrate the poem and take turns reading during a creative shared reading session.

Students investigate the concepts of geometry that can be grouped into a flip book that can be used for teaching and review purposes. They define the differences between two and three dimensional figures. Also polygons are reviewed and...

Young scholars explore measurements by completing worksheets in class. In this geometry lesson, students identify the basic measurement units in both the English and metric systems. Young scholars analyze 2 and 3 dimensional objects and...

Fourth graders examine faces, edges, and vertices. In this geometry instructional activity, 4th graders participate in classroom activities that require them to compare geometric shapes, figures, and models.

Fifth graders create a net for a given polyhedron. They determine the corresponding polyhedron for a given net. Students investigate several polyhedra (cube, tetrahedron, and one of their choosing) and their corresponding nets. They...

Fifth graders use pattern blocks and triagular grid paper to reivew shape names, be introduced to the concept of a tiling of the plane, and determine which pattern blocks tile the plane. They are asked if they comprehend what a...

Students explore geometric vocabulary through creation of shapes on a geoboard. They present design attributes, transfer of design, and color-coding components mix to create a fun and exciting lesson that stretches student thinking.

Third graders explore the concept of symmetry using geometric shapes, capital letters and various other shapes. They fold shapes to show symmetry, draw lines of symmetry and create symmetrical designs.

Learners are introduced to the concepts of translation, reflection, and rotation. They practice translating, reflecting, and rotating two-dimensional objects on the coordinate plane. students use computers to learn about the three concepts.

Students explore the relationship of angles as it relates to 2 and 3-D shapes. In this geometry lesson, students differentiate between acute, obtuse, right, alternate interior, exterior and adjacent angles. They manipulate a math...

Students identify different types of polygons. In this geometry lesson, students differentiate between convex and regular shapes. they identify the names of two and three-dimensional objects.

Sixth graders explore the relationship between area and perimeter. After discovering the definition of perimeter, 6th graders work together to create designs for a flower bed. They observe that the perimeter remains constant even...

Students make conjectures of intersecting circles. In this geometry lesson, students observe circles and their position in space. They investigate and observe two and three dimensional objects.

Third graders explore vocabulary associated with three dimensional figures.  In this transformations lesson, 3rd graders create two dimensional nets for three dimensional figures.  Students become familiar with describing two...

Sixth graders compute the surface area. In this surface area lesson students are given a set of problems to calculate. They compute the surface area of cubes and rectangular boxes.

Students discuss methods of building forms with clay (ball and variations, snake, flat sheets). They draw a stick figure of what their sculpture may look like, including correct figure proportion.

Pupils identify and define intersecting lines and vertical angles. They draw two intersecting lines and measure one pair of vertical angles. Learners will also move a line to change the angles of a figure and describe the changes in the...

Students work together to make figures out of tangram squares. In groups, they calculate the measurements they need and apply the Pythagorean Theorem. They complete a worksheet solving equations using the theorem and review their answers.

Students explore geometric concepts by working with Tangram Puzzles. In this Tangram challenge lesson, students use problem-solving tasks that involve physical manipulatives. Students select a picture and use all seven pieces...

Young scholars use 3-dimensional materials to create a simple 3-D object. They think about different ways the object could be sliced. Students choose one way to slice the object, and draw the sliced shape on paper or computer. Using a...

In this molecule worksheet, students use a molecular model kit to build the molecule, draw a three-dimensional structure, and describe its shape. This worksheet has 2 graphic organizers.

Learners identify and name different geometrical shapes. In this math lesson, students distinguish odd from even numbers. They describe the properties of 2 and 3 dimensional objects.
