Geometric transformations in algebra ... what? Given four transformations, the narrator explains how each affect the graph of the original function. The transformations involve translations and reflections, both horizontally and...

Finalize the plans before playing in the sand. Learners design sandcastles using geometric and composite figures. They create blueprints, including the scale, and three-dimensional models of their castles. Finally, scholars calculate the...

Build upon the Pythagorean Theorem with the Law of Cosines. The 10th part of a 16-part series introduces the Law of Cosines. Class members use the the geometric representation of the Pythagorean Theorem to develop a proof of the Law of...

Demonstrate the application of algebra to geometric angle relationships with an activity that asks learners to use what they know about adjacent and vertical angles to write algebraic equations. Diagrams become more complex in this...

Students examine geometric shapes. In this geometric shape lesson plan, students examine how geometric shapes flip, turn, and slide to create a pattern. Students analyze the role that quilts played in helping slaves escape to freedom. ...

Sixth graders explore pattern recognition and sequencing. They create arithmetic and geometric sequences with colors, shapes, and numbers. Students write expressions of arithmetic sequences and geometric sequences to find the nth term.

Tenth graders construct geometric figures using compasses and protractors.

Students create posters about geometric shapes in order to demonstrate their understanding of the different shapes. Students look for pictures in magazines to represent two-dimensional shapes, paste them on a poster, label the shape,...

In this sequences and series worksheet, students find the sum of a given geometric series. They use sigma notation to express a geometric series. This one-page worksheet contains 12 problems.

In this sequences and series worksheet, 10th graders solve and complete 13 different problems that include infinite geometric series. First, they find the sum of each infinite geometric series. Then, students find the first three terms...

Learners investigate the properties of lines and congruent triangle theorems as well as apply geometric properties and relationships to real-world mathematical problems. Given two different scenarios, they examine maps that have been...

Students explore the concept of geometric patterns. In this geometric pattern lesson, students use Microsoft Excel to explore geometric patterns. Students analyze growth rates of pattern growth. Students create their own patterns and...

Pupils create a Holocaust memorial. In this interdisciplinary lesson, students use geometric shapes or forms to create a Holocaust monument.

Students select a geometric figure and find an example of the figure in their surroundings. They photograph the figure and write a proof to accompany it. They match photos to proofs.

Second graders draw a model using correctly formed geometric shapes. In this geometric shapes lesson, 2nd graders notice geometric shapes in the world around them and accurately draw these shapes.

Pupils research how engineers and scientists generate linear and angular measurements with geometry to survey the Earth and Mars. They assess how geometric shapes affect navigation. A surveyor comes to the classroom and explains how he...

Seventh graders visualize and identify geometric shapes after applying transformations on a coordinate plane. In this tangrams lesson, 7th graders construct a set of tangrams and then answer extension questions related to measurement,...

Fourth graders capture geometry in nature. In this nature of geometry lesson, 4th graders use digital cameras to find real life examples of geometric terms.  Students create a presentation using the digital pictures and terms with...

Ninth graders design a safe passage through a 2-D obstacle. In this geometric math lesson, 9th graders engage in a hands on activity to better understand the concept of geometric and algebraic perpendicularity. Students will work in...

Students play a game in which they name geometric shapes. In this geometric shape lesson, students ask "yes and no" questions to determine which shape one of their classmates has chosen. They ask questions that lead them to the name of...

Sixth graders identify and use area formulas for finding the area of geometric shapes.

Fifth graders view prints of M.C. Escher's work. They look at examples of geometric figures and polygons and discuss places they have seen them. Students create their own tessellations. They write a report about the process they used in...

Fifth graders explore the context of how and when to use tangrams in geometry. They create and draw a number of different geometric figures using tangrams. Students work on their visual spatial skills.

Students research tall buildings and identify the geometric shapes used in the construction of the buildings. They compare shapes and infer why some are better than others in building. They produce a multimedia presentation of geometric...
