Fifth graders investigate circles and area. In this geometry instructional activity, 5th graders find the area, diameter and circumference of a circle. They estimate the data and then calculate it.

Seventh graders investigate geometric shapes using tessellations. For this geometry lesson, 7th graders practice tessellations using different shapes. They create different designs using tessellations.

Sixth graders investigate different types of angles. In this geometry lesson, 6th graders use a protractor to identify acute, obtuse, and straight angles.

Students investigate the elements of a pattern.  In this geometry lesson plan, students identify different shapes in a pattern and discover which shapes are missing in order to extend it.  Students create their own patterns...

Students draw conclusions and make conjectures given a specific scenario. In this geometry lesson, students model real life scenarios using properties of triangles. They model number facts and explain why the outcome is what it is.

Students solve right triangles using trigonometry. In this geometry lesson, students use the unit circle to identify different trig values. They identify the six trigonometric identities.

Young scholars calculate the speed, motion and distance of a projectile. In this geometry lesson, students obtain measurements while calculating velocity. They graph their results and make predictions.

Students identify the relationship between the radius and Pi. In this geometry lesson, students calculate the circumference and area of a circle. They create visuals to help them see how the circumference relates to Pi.

Students solve for the different ratio and proportion of a problem. In this geometry lesson plan, students show their knowledge of how to solve proportional relationships. They convert between percent, decimals and fractions.

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

Students calculate the surface area and volume of a sphere. In this geometry lesson, students define nets, surface areas and volume of prisms, pyramids, cylinders and cones. They use the computer to create nets and analyze shapes.

Students define Pascal's triangle and special notations used to represent nth elements. In this geometry activity, students solve problems using permutations and combinations. They compare the formula for permutation to that of Pascal's...

Students investigate image and pre-image. In this geometry lesson, students identify the reflection and rotation of different shape on a coordinate plane. They identify similarities and differences of image and pre-image of a reflection.

Students use the Pythagorean Theorem to solve problems. In this geometry lesson plan, students complete problems with different percents of accuracy as they use the Pythagorean Theorem. Students answer verbally to verify they understand...

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

Students recognize patterns and sequences in numbers. For this geometry lesson, students create rules to define the sequences and patterns they obsere. They translate coded messages as they dicuss navigational terms.
