Rotational Symmetry of Polygons and Other Figures
Students explore geometry by participating in a shape rotation experiment. For this symmetry lesson, students identify the term symmetry and a list of other geometry vocabulary. Students analyze shapes as they are turned 90 degrees and...

Pass It On
Fifth graders participate in a class activity that helps them learn some geometric terms along with their definitions. They describe relationships between two and three-dimensional shapes and analyze attributes and properties of...

Mars Pathfinder Egg Drop and Landing
Students construct a pathfinder that could land an egg safely. In this physics lesson, students explain the factors affecting the dynamics of falling objects. They evaluate their pathfinder design.

Speaking Geometrically
Fourth graders are introduced to the vocabulary needed to identify the attributes of two and three-dimensional figures. They work together to create a word wall, which contains the geometric terminology being learned.
Curated OER
Odd Thing Out
Pupils listen to the math problem provided and work in groups to solve. They think about the objects and write down their information in a table. Class construct the table on a large piece of paper that can be put on the wall after the...

Finding The Center Mass of a Triangle
Students calculate the center mass of a triangle. In this geometry lesson, students use the median to find the center mass. They discuss the different characteristics of triangles and their center of mass.
