Tenth graders connect the history of geometry to problem solving. In this geometry lesson, 10th graders investigate polygons through hands on manipulatives and solve problems relating to parallelograms and triangles. They calculate the...

Students compute surface area and volume of prisms. In this surface area lesson plan, students find the surface area and volume of rectangular and triangular prisms. Independently, students use their computers to determine the volume,...

Tenth graders investigate the history of geometry and its different shapes. In this geometry lesson, 10th graders practice seeing three dimensional shapes and explain why there are only five polyhedra. They relate all the new materials...

Students differentiate between inductive and deductive reasoning. For this geometry lesson, students identify congruent figures and examine logos for congruency.

Examine the application of the Pythagorean Theorem in problem-solving questions. Pupils apply the theorem to find lengths when given different scenarios. They finish the 17th installment in an 18-part series by applying the theorem...

In this geometry worksheet, 10th graders solve problems involving triangular inequality. They apply the proofs and theorem of triangles to solve these problems. There is an overview and one question.

Tenth graders explore parallel and perpendicular lines.  In this geometry activity, 10th graders investigate the relationships associated with parallel lines and transversals, perpendicular lines, and the angles formed by these...

Students role-play as engineers designing wedge tools. They devise methods for shaping quarry rocks into pyramid blocks. Following a teacher demonstration, they use materials such as soap, clay, and foam for blocks and wood, plastic,...

Have the class learn about and make conjectures about a line intersecting a cubic.  In this making conjectures about a line intersecting a cubic lesson, students draw lines that intersect a cubic at three different points. ...

Tenth graders pretend to set up an ice cream shop in a make believe town of shapes.  In this geometry lesson, 10th graders work together to put up an ice cream stand in an ideal location and solve for the minimum given the shapes.

Tenth graders investigate the theorems of angles and lines to prove triagle sum theorem. In this geometry lesson plan, 10th graders discuss the theorems of triangles and how it is used to solve for missing sides or angles. They review...

Triangles, triangles, and more triangles! In this second installment of a 36-part series, your young mathematicians explore two increasingly challenging constructions, requiring them to develop a way to construct three triangles that...

Young scholars discover that side measurement is used in determining angle classification of a triangle. By squaring sides, they predict whether triangles be right, obtuse, or acute. They prove the Pythagorean Theorem and use it to solve...

Learners determine the number of paths in a network with up to six vertices. They construct a network to solve a problem situation. They describe and defend the solution to a network problem.

Students explore the building of a pyramid and how pulleys were used to change the direction of applied force. They demonstrate the mechanical advantage of using a pulley and apply it to modern engineering.

Students identify various geometric shapes. Apply the given formulas to determine the volume of these shapes. Design their own container to conform to specifications provided. Use their knowledge of volume formulas and shapes to compute...

Students experiment with common objects such as spools, string and soap to determine how pulleys make it easier to move large objects. They look at the difference between fixed and movable pulleys. They examine the many uses engineers...

Students use everyday materials (milk cartons, water bottles, pencils, straws, candy) to build a small-scale transportation device that incorporates the wheel and axle and the lever. They race their carts/trucks, measure distance, time...

This lesson focuses on Euclid's Axioms, simple, intuitive statements, that everyone agrees are true. An axiom(or postulate) is a mathematical statement that is regarded as "self-evident" and accepted without proof. A key part of...

The introduction of this lesson plan has students verifying the famous Pythagorean Theorem with a hands-on proof. Students will then apply the Theorem in one of two ways: by solving for the side lengths of a right triangle and by...

This short lesson focuses more on the angle bisector theorem. Learn about the angle bisector theorem proof, triangle angle bisector theorem, how to construct angle bisector, and other interesting properties and facts around angle bisectors.

This lesson explores triangle inequality theorem, triangle inequality theorem-proof, and triangle inequality theorem problems. Try the hands-on triangle inequality theorem calculator and interactive problems to have a better...
