Students use triangles to find the length and slope of each side. After connecting the vertices, they add points based on their specific instructions. They use the Pythagorean Theorem to complete a worksheet to end the lesson.

Second graders are introduced to geometry by a teacher made puppet called Geo George.

Students review geometry unit content through a vocabulary/word game. They demonstrate understanding using geoboards to answer questions. They work in groups and it's a race to the correct answer.

Pupils add up the different angles using the angle addition postulate. In this geometry lesson, students differentiate between interior and exterior angles. They calculate the different angles for triangles and use proof to show their...

Students create lines and shapes with a compass and a straight edge. In this geometry lesson, students investigate square roots, irrational numbers and spirals. They explore nature to see the shapes representing mathematics and geometric...

Learners identify the different properties of Euler's Characteristics. In this geometry lesson plan, students identify the shape and surface a polygon. They relate the concept of Euler to solving real world problems.

Learners use the Pythagorean Theorem to solve problems. In this geometry instructional activity, students solve for the distances by calculating the different parts of the shape of a two and three dimensional shape. They reason by analogy.

Sixth graders investigate the area of polygons. In this geometry lesson, 6th graders calculate area of prisms using geometric formulas. They work with prisms and other rectangular shapes.

Students identify the interior and exterior measures of polygons. In this geometry lesson, students identify the formula for interior angles of polygons. They differentiate between triangular and polygons angles.

Second graders explore the features of triangles and quadrilaterals. In this lesson on triangles and quadrilaterals, 2nd graders rotate with their group to five different activities all exploring a different aspect of geometry.

In this geometry worksheet, learners draw a shape based on the directions. They tell the reasons the four resulting circles are concurrent. A sample drawing is included.

In this angles in polygons worksheet, students determine the value of a missing angle measure. They find the value of interior angles and exterior angles. Polygons include triangles, quadrilaterals, pentagons, and hexagons. This...

Students calculate the center mass of a triangle. In this geometry lesson, students use the median to find the center mass. They discuss the different characteristics of triangles and their center of mass.

Students work with three dimensional objects. In this geometry lesson plan, students examine models of spheres, cones, cubes, prisms, and pyramids, and identify them by their edges, vertices, and faces.

Students use shape puppets to review geometry content. They take turns singing songs, reading students poems, reciting class bulletin board notes and choral poems. They prepare for their summative assessments through play and interview...

Learners go through various construction techniques needed to bisect angles, lines and arcs, construct a perpendicular from a vertex to a line, construct the center of a circle, transfer an angle, and various other constructions normally...

Young scholars construct the tangram pieces from a square paper by following directions to fold and cut. They make observations on the pieces formed and compare how they are related to each other. They explore patterns and shapes with...

Learners investigate the symmetries of a convex quadrilateral in a collaborative activity. Rigid motion and complements are explored as learners analyze different cases of reflections across a line.

Help your learners examine triangles. Pupils explore the different sizes and measurements of triangles. They discover triangles can be isosceles or scalene, and examine the attributes of triangles. Here is the website where you can...

For this rigid transformation worksheet, students follow directions to translate, reflect or rotate a figure in a coordinate plane. Examples and explanations are provided at the beginning of the document. This two-page worksheet contains...

Brilliant graphics depict a variety of allotropes, especially the allotropes of carbon. Some notes are available to help make these useful for teaching your young chemists, but not for every slide. With some additional preparation on...

Students explore the concept of translations. In this translations lesson, students discuss similarities and differences between images and pre-images. Students apply translations to coordinates of figures. Students use patty paper to...

Young scholars cuminate their study of molecular structure and bonding with this activity.

Junior geometers discover that polygons can be decomposed into triangles and that the number of triangles can be determined by a rule. Note that the Geometer’s Sketchpad® software is required to carry out all components of this...
