Geometry is everywhere, and I mean everywhere! Those skillful mathematicians discuss shapes and then come up with a well-researched list of shapes seen in everyday applications. They put their knowledge of shapes to work as each small...

Students research Pythagoras and learn how to apply his theorem. They solve real life problems using the theorem and demonstrate knowledge of exponents, equations, and radicals. Students include diagrams in their research papers.

Students complete worksheets involving rotational symmetry. In this geometry lesson plan, students complete worksheets to identify rotational symmetry and rotations. They compare and contrast rotated figures. Students examine the...

In this measuring angles review learning exercise, students use their math skills to solve 6 problems that require them to estimate and measure each of the 6 angles.

Elementary schoolers explore 3-D shapes. They transition from thinking of shapes as only 2-D. Pupils read Cinderella as a launching activity for their upcoming adventure, and explore a new world of 3-D shapes in this introductory lesson.

Students explore the concept of similarity and congruence. In this similarity and congruence lesson, students cut out strips of paper and form a triangle. Students try to prove that their triangles are congruent using the SSS theorem of...

Students explore the concept of similarity and congruence. For this similarity and congruence lesson, students identify and verify whether or not two figures are similar, congruent, or neither. Students use postulates and theorems such...

Young scholars construct two-column proofs. In this geometry lesson, students use deductive reasoning and geometric properties to justify given geometric statements. Young scholars compare and contrast proofs.

Fifth graders find perimeters, areas, and volumes of everyday objects and state the precision. They work in small groups in order to take measurements, perform calculations, and write a group report about the investigation.

Students explore similar figures. In this surface area and volume lesson, students identify the relationship between the surface area and volume of similar figures.

In this congruence of triangles worksheet, 10th graders solve 10 different problems that include determining the congruence of various triangles. First, they determine the length of two sides of a congruent triangle. Then, students...

Young scholars pick different objects and measure the shadow they cast. In this geometry lesson, students experiment with shadows using a flashlight and an object to cast a shadow. They measure and differentiate between the shadow and...

Students explore the concept of the Pythagorean Theorem. In this Pythagorean Theorem lesson, students derive the distance formula and slope of a line from the Pythagorean Theorem.

Students explore the concept of constructions, sketches, and drawings. In this constructions, sketches, and drawings lesson, students discuss the differences between constructions, sketches, and drawings through teacher led discussion.
