Tenth graders investigate where in the real world triangles are used. In this geometry lesson, 10th graders write an essay describing where in their lives triangles are used. They can use food, buildings, clothing or anything triangular...

Tenth graders analyze graphs and by comparing trees. In this geometry activity, 10th graders investigate the use of different graphs using bar and regular graphs. They work groups at the computer.

Students are being evaluated on their math skills. In this algebra lesson, students review basic math skills and are being reviewed for leaning skills that may enhance or inhibit their learning skills. They are scored based on a special...

Learners explore geometry by analyzing different shapes. In this shape identification lesson, students discuss the characteristics that make certain shapes unique and the same characteristics that cause shapes to look the same. Learners...

Upper graders access the Microsoft Word program and create patterns by utilizing certain keys on the keyboard. They create picket fences, smiley faces, and hearts. It seems that this lesson has as much to do with keyboarding skills as it...

Students investigate points and angle bisectors. In this geometry lesson, students define angles, bisectors and perpendicular bisectors. They analyze angles and bisectors using Cabri software.

Students construct parallel lines using a protractor and a straightedge. In this geometry lesson, students identify the properties of parallel lines. They use Cabri to graph and observe the lines.

Students compare and order numbers. In this geometry instructional activity, students write equations for inequalities. They differentiate and apply concepts of triangular properties to solve problems.

Students identify the measure of missing exterior angles. In this geometry lesson,students define and apply the exterior angle theorem to solve problems. They use Cabri software to create different angles and make investigations.

Students construct triangles. In this geometry lesson, students create equilateral triangles. They also construct triangles where the sides are different. They use the lab to create and move shapes around with the Cabri program.

Tenth graders find the incenter of a triangle. In this geometry lesson, 10th graders define the way to create an incenter with an angle bisector. They differentiate between incenter and incircle.

Students solve problems using fractals. In this geometry lesson, students identify properties of fractals. They find patterns in their surroundings and relate it to the real world and math.

Students build and apply concepts of geometry. In this geometry lesson plan, students create a building using proportions and scale drawings. They use Cabri technology to create a virtual drawing first.

Pupils investigate and solve Pythagorean triples. In this geometry lesson, students find the missing sides and angles of a right triangle. They graph right triangles and move the sides around to create different angles.

Students investigate the Pythagorean triples. In this geometry instructional activity, students solve for different parts of a right triangle. They identify the missing side or angle using the pythagorean theorem.

Learners construct perpendicular lines. For this geometry lesson, students use a compass and straight edge to do construction. They start from a point to a line.

Students use Heron's formula to calculate the area of a triangle. In this geometry lesson, students use three different methods to solve the area of a triangle. They find and construct the incentor and angle bisector of a triangle.

Students calculate the distance from the vertex of a triangle to the center. In this geometry lesson, students find the shortest distance between a point and the vertex of a triangle. They relate this concept of distance to the real world.

Students explore the application of Hinge Theorem. In this geometry lesson, students write inequalities, given two sides of a triangle. They solve problems with triangular inequalities using the proper theorem.

Students construct using Cabri software. In this geometry lesson, students convert between units and apply the correct measurements to build objects. They create the room virtually and manipulate the shapes to the desired measurements.

Students calculate the inscribed angle of a triangle. In this geometry lesson, students identify the angle created by intersection of a triangle and a circle. They see the relationship between the arc and the angle.

Students perform reflections and translations of polygons. In this geometry lesson, students perform reflection in two parallel lines. They use Cabri to observe the transformation and rotations of each shape.

Children begin by making direct comparisons between objects and putting a number of objects into order according to length. They are also introduced to measuring with multi-link cubes which allows them to compare objects which cannot be...

Is it a right triangle or not? Introduce scholars to the converse of the Pythagorean Theorem with a lesson plan that also provides a proof by contradiction of the converse. Pupils use the converse to determine whether triangles with...
