The Geometry of Means
In this geometry worksheet, students are given a rectangle and a square. They verify ratios when given equal perimeters or areas. Students are given adjacent squares. They find the distance between the centers, and identify the means...
Curated OER
Dizzy Heights
Fifth graders explore ways to measure the height of an inaccessible object. They measure lengths using a tape measure or ruler. Students measure angles using a protractor and estimate heights.
Curated OER
Reflections
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.

I Spy Shapes
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...
Curated OER
Shapes Are Everywhere
Third graders explore pattern blocks noticing their similarities and differences and share their observations with others. They classify shapes by discussing sides and angles and combine pieces to make new shapes.
