Curated OER
Mirror, Mirror
Geometry students use hinged mirrors to discover that the regular polygons are composed of triangles tessellating around a center point. They sketch triangles on paper models of the regular polygons having 3 to 10 sides and compute the...
Curated OER
Frieze Patterns And Tiles
Students investigate geometry with the use of a creative project. They review relevant vocabulary that includes turn, flip, side, and angles. Students also practice conducting transformations used as inspiration for the project. Then...

We've got the whole world in our hands
Students explore spatial sense in regards to maps about the globe. In this maps lesson plan, students label oceans, locate the continents and poles, follow directions, and explain the symbols on a map.
Curated OER
Identifying Angles
Fourth graders discuss and examine examples of the different types of angles. After learning the names of the geometric shapes students identify the types of angles and then complete the Kidspiration activity, Identifying Angles.

Making Triangles
Students use interactive geoboards to identify simple geometric shapes. In this making triangles lesson, students describe the properties associated with geometric shapes. Students develop spatial sense and the mathematical meaning of a...
Curated OER
Piece It Together
Second graders develop spatial sense, such as above and below. In this spatial sense lesson, 2nd graders go on a scavenger hunt and to piece together the clues. Each clue has a question using spatial vocabulary.
Curated OER
Two-Dimensional Drawings from Three Dimensional Objects
Sixth graders identify and replicate two dimensional illustrations of three dimensional objects. In this spatial visualization lesson, 6th graders practice viewing objects from various sides. Student participate in stations to view...
Curated OER
Spatial Connections
Students use maps, scales, and describe locations in order to learn about spatial sense. In this spatial sense lesson plan, students participate in many activities for this spatial sense unit that should last throughout the year.
Curated OER
Introducing Angles
Sixth graders identify, compare and interpret the characteristics of polygons and angles in order to meet spatial sense, geometry and measurement standards. They also sort shapes into three categories, polygons (regular and irregular)...
Curated OER
Geometry Flip Book
Students investigate the concepts of geometry that can be grouped into a flip book that can be used for teaching and review purposes. They define the differences between two and three dimensional figures. Also polygons are reviewed and...
