Narrow It Down
Ever played 20 Questions? A similar game helps young learners practice asking and answering yes-or-no questions. Spread out several objects, preferably all similar with slight variations (buttons or coins would work well). A leader...

Granary Door Dogon, Mali
Young scholars explore a creation myth. In this visual arts lesson, students discuss the Dogon creation myth and the design and make refrigerator magnets in the style of Dogan granary doors. The design of the magnets should include...

Investigation - Looking at Polygons
Middle schoolers construct polygons by plotting points on a coordinate plane. Pupils connect the points and identify which polygons they have drawn. They will need graph paper to carry out the assigned activities. A vocabulary list,...
Curated OER
Tangram Perimeters
Students work together to make figures out of tangram squares. In groups, they calculate the measurements they need and apply the Pythagorean Theorem. They complete a worksheet solving equations using the theorem and review their answers.
Curated OER
Polygons
Fourth graders identify and describe lines, shapes, and solids using formal geometric language. They use Inspiration to create a graphic organizer and outline of polygons.
Curated OER
Tiling the Plane
Students use pattern blocks and triangular grid paper to review shape names, be introduced to the concept of a tiling of the plane, and determine which pattern blocks tile the plane. They are asked: "Have you ever seen a floor or a wall...
Curated OER
THE MEAN INDEX CARD
Learners cut an index card to create three similar right triangles and explore the congruencies and proportions that exist. They investigate the properties of lines and concepts of congruency, similarity, tangency and symmetry of...
Curated OER
Rectangles Tracing
In this math worksheet, students study the geometric shape of the rectangle by tracing 10 shapes and coloring them different colors.
Curated OER
Geometry: 3D Objects
In this math worksheet, students examine 4 pictures of 3D objects and write the name of each. Students then study 3 pictures and figure the number of faces, edges and vertices on each.
Curated OER
Line, Line Segments and Rays
In this geometry worksheet, learners identify items as either lines, line segments or rays by checking the appropriate box beneath each figure.
Curated OER
Congruence with Robot Gobot
Students identify the properties of solids and polygons. In this geometry lesson, students identify the different measurements of a triangle. They use congruence parts and theorem to prove their answer.
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
"Geotown" Scrapbook
Students create a scrapbook. In this geometry lesson, students use digital cameras to take pictures of geometrical concepts. Students use the pictures to create a "Geotown" scrapbook.
Curated OER
Navajo Rug
Students explore geometry in Navajo rugs. In this shape art lesson plan, students create a Navajo rug design using triangles and squares. Students investigate designs on the Internet and then create an original design.
Curated OER
Symme"tree"
Learners practice drawing lines of symmetry after the teacher draws shapes on the board. They create a class symme"tree" using only symmetrical shapes to decorate it.
Curated OER
More Prisms/Nets
Young scholars calculate the volume and surface are of three-dimensional shapes. In this geometry lesson, students use the nets to prove their calculations of shapes. They identify the different parts of a solid using the nets.
Curated OER
Transformation
Third graders investigate symmetry by reflecting objects in different angles. In this geometrical transformation lesson, 3rd graders define the terms translation, rotation and reflection in order to physically turn geometric...
Curated OER
Sketching Pyramids
Learners sketch and identify properties of pyramids. In this geometry instructional activity, students create nets to identify three dimensional shapes. They sketch cones, prisms and pyramids.
Curated OER
The Geometry of Indigenous Art
Students examine the concepts of symmetry, rotations, reflections, translation, dialations, and tessellations and apply them to indigenous art. They also do Internet research and create artwork (painting, pottery, computer graphic design).
Curated OER
Sketching Cones
Students sketch cones and identify its properties. In this geometry lesson, students calculate the surface area and volume of each three dimensional shape. they define and sketch prisms, pyramids and cylinders.
Curated OER
Classify Prisms
Learners classify prisms according to their attributes. In this classifying prisms lesson plan, students explore different prisms. Learners generate observations of the attributes and classify the prism correctly.
Curated OER
Sketching Prisms
Students sketch and create nets of different polygons.In this geometry instructional activity, students differentiate prisms from other three-dimensional shapes. They define the properties of prisms.
Curated OER
Sketching Cylinders
Students create nets of cylinders. For this geometry lesson, students calculate the surface area of cylinders and other solids. They show their understanding of three-dimensional shapes by solving problems.
Curated OER
Symmetry
Learners make a design with pattern blocks and then pass them on to the rest of the class. They have to make them symmetrical and complete the design.
