Students explore triangles. In this geometry lesson, students will create note cards with pictorial depictions of right, acute,obtuse, scalene, isosceles, equilateral and equiangular triangles. Students will verbally describe each type...

Students complete two column proofs. In this geometry instructional activity,students derive the reasons their answers are correct using logic. They write the proof step by step using two columns.

Students relate topology to polygons. In this geometry lesson, students make the connection between different shapes and topologically equivalent relationships. They use Mobius strips to create and move shapes around.

Pupils use fractals to analyze nature. In this geometry lesson, students work in groups using technology and math to communicate. They identify where in the real world fractal can be seen.

For this center of the circle worksheet, 10th graders solve 5 different center of the circle measurements. First, they draw a circle and add two points on it. From there, students construct a line segment and a midpoint on the line...

Students calculate the ratio and apply it to construction. For this geometry lesson, students convert between different units and use decimals and fractions interchangeable. They find the fraction of a given amount using the...

Students develop an understanding of pi and the relationship between the diameter, radius and circumference. After a lecture/demo, students use construction paper and a compass to solve problems using diameter, radius and circumference.

Students investigate track and field dimensions, measure an actual track, and construct a scale model. The use of a meter stick, dimensional analysis, and the application of the distributive property to variables forms the main focus of...

Students utilize triangulation techniques to determine altitudes of objects. An altitude locator is constructed and used to determine the height of a building or a tree. Tangent tables and formulas provide the ratio for the formula to...

Students build a kite while integrating math and science. In this kite building activity, students construct a blueprint and apply mathematical formulas while constructing a kite. They use appropriate flight and kite terminology to...

High schoolers create three dimensional shapes using concept maps. In this geometry lesson, students investigate the impact of mental schemas on humans. They collect data on this topic and plot their data on a coordinate plane.

Students work collaboratively to design and construct a roof out of Legos for a house that was built in a previous lesson plan. The roof must be structurally sound and pass certain criteria determined by the teacher.

Students are introduced to polyhedrons through using straw models to explore geometric solids and constructing Christmas tree ornaments using Epsom salt crystals. Students will view interactive videos and investigate and retrieve...

Students follow directions to make a stained glass window design of regular and irregular polygons with specific geometric elements. In this geometry lesson plan, students also analyze other classmate's designs.

Students solve real life scenarios using math. In this geometry instructional activity, students collect, predict and interpret data. They measure a chair using different measurements and choose what would make the chair the best design.

Young scholars use geosketch ro create a fence. In this geometry lesson plan, students identify the amount of material and area needed to create a fence. They calculate the perimeter and surface area of their fence.

Learners identify the different properties of polygons. In this geometry lesson plan, students differentiate between polygons and non-polygons. They review important vocabulary to help them understand the properties of polygons.

Students use the Internet to answer lab questions about fractals, and then construct fractals using the initial stage and iteration rule. They complete tables and generate rules for the "nth" term and create their own fractals.

Fifth graders discover lines of symmetry for shapes and everyday objects. In this lines of symmetry lesson, 5th graders use a butterfly outline to find lines of symmetry. Students analyze everyday objects for symmetry and use...

Students explore the history of Pythagoras and his contributions to mathematics. In this middle school geometry lesson, students use one inch tiles to investigate the Pythagorean Theorem and to find the length of the sides of a right...

Learners compare two lengths using the area of a square. In this geometry lesson, students solve problems using ratio and proportion of the two shapes. They solve equations by taking the square root of both sides.

Learners create graphs of circles. In this geometry lesson plan, students use Microsoft Excel to create graphs. They construct the graphs using paper and pencil as well as the computer.

Eighth graders explore congruent and similar figures.  In this eighth grade geometry lesson, 8th graders use geoboards to create congruent and similar figures and explore the relationships between the sides and angles. 

Students identify shapes that will tessellate. They construct a tessellation using transformations. Students identify transformations in tessellations. They identify applications of transformations such as tiling and fabric design.
