Shape Makes a Difference!
Learners learn the difference between perimeter and area by watching a video and a hands on activity.
Curated OER
Perimeter and Area of Similar Figures
Students explore the relationships between similar figures. In this relationships between similar figures lesson, students discuss relationships between perimeter, circumference, area, surface area, and volume of similar figures through...
Curated OER
Spatial Relationships
Students investigate the geometry concept of spatial relationships. They draw a replica of a cube. Students list the planes on the cube and go into further depth with identifying the parallel line in segments of the cube. The...

Shape Detectives
Students become "shape detectives" as they identify, name, create and describe common shapes within pictures and objects found within the learning environment. Suggestions include incorporating shapes into all learning areas and daily...
Curated OER
Reflections
Fifth graders create a reflection of a poygon using a Mira. They discover that a line connecting a vertiex of a polygon and the corresponding vertex of its reflection is perpendicular to the line of reflection. Students create a glide...
Curated OER
Investigating Area and Perimeter of Polygons.
Student sinvestigate the area and perimeter of polygons. They differentiate between similar and congruent polygons.. They identify the ratio and proportions of the sides and angles of polygons.

Beginning Map Skills
Maps can be so much fun, they help you understand spatial relationships, distance between objects, and can foster direction skills. Budding cartographers with visual impairments use the Wheatley Tactile Diagramming Kit to create their...
Curated OER
Watching Wheatstacks
Students explore basic shapes in Monet's paintings Wheatstacks, Snow Effect and Morning. They study about light and shadows through reading and experimenting with three-dimensional models and flashlights.
Curated OER
Investigating Lengths of Segments in a Triangle
Pupils explore the midsegment of a triangle in the geometry lesson. They draw and measure the segment joining the midpoints of the two sides of a triangle and compare its length to the length of the third side of the triangle. The...
Curated OER
Animal Tracks
Students are introduced to the topic of area. In groups, they share various techniques to help them identify different shapes and work together to calculate the area. They use this same knowledge to determine the area of animal tracks...
Curated OER
A Holocaust Monument
Students examine Holocaust memorials to discover expressive power of shapes, practice creating simple geometric shapes or forms, and practice calculating ratios, area, and/or volume.
Curated OER
A Holocaust Monument
Learners create a Holocaust memorial. In this interdisciplinary instructional activity, students use geometric shapes or forms to create a Holocaust monument.
Curated OER
Cafeteria Mayhem
Students design a cafeteria floor plan. For this area and perimeter lesson, groups create an efficient lunchroom layout on poster board by using geometric shapes and formulas as the basis for their designs. In the accompanying writing...
Curated OER
What Goes Around
Fourth graders investigate the relationships between the area and perimeters of squares and rectangles. They calculate the perimeter of rectangles and squares using a formula. Students investigate the relationship between the perimeter...
Improving Measurement and Geometry in Elementary Schools
Rep Tiles
In addition to the catchy title, this lesson plan provides upper graders an opportunity to more closely scrutinize the attributes of plane figures. In particular, they focus on the similarity of different shapes. Both whole-class and...
Curated OER
Area graphics for 7th graders
Students randomly select dimensions for three geometric shapes (square, right triangle and circle). From the graphs they compare and contrast the graphical results of each shape.
Curated OER
Castles
Students create a scale model to a castle using the dimensions they were given. They calculate the surface areas and volumes of each section of their castle.
Curated OER
Symmetry in Relief
Students explore radial symmetry. In this 3 dimensional art and geometry lesson, students identify examples of radial symmetry in everyday objects. Students create an imprint using radial symmetry on clay tiles.
