Study the Graph
In this graph worksheet, students study colored shapes plotted on a Cartesian coordinate plane. Students identify the "right" and "left" coordinates for each shape. The page should be duplicated in color.
Curated OER
Geo-Mat
Students review plane figures by playing a game that resembles "Twister." They listen to directions to locate a large example of the figure which is placed on the floor.
Curated OER
Know Your Polygons!
Young scholars identify and categorize different polygons. In this polygons lesson plan, students research and identify properties of polygons, identify different polygon shapes, and categorize different triangles and quadrilaterals.
Curated OER
Pop-it...Stop-it
Students observe how certain geometric shapes can be used to make some structures rigid and others flexible. The activity involves construction of a 30-60 right triangle, folding while following directions, and identifying polygons.
Curated OER
Symmetry of Road Signs
Students identify symmetry in road signs. For this geometry lesson, students explore objects in the real world for symmetry. They perform translation, rotation and reflection.
Curated OER
Polynominoes
In this polynominoes worksheet, students solve 9 different types of polynominoes problems. First, they identify that a polynominoe is a polygon made from squares of the same size and connected to each square. Then, students determine how...
Curated OER
Graphing Greenery
Students gather leaves and trace them on graph paper. They plot coordinates that approximate the shape of the leaves and share those coordinates as "worksheets" for other students to complete.

Problem Solving Using Power Polygons
Students investigate geometric shapes by creating figures on a plane. In this polygon lesson, students complete a worksheet based on the angles in a power polygon. Students identify the different types of polygons and define their...
Curated OER
Sort it Out
Students identify and sort a variety of two- and three-dimensional objects and compare and contrast their attributes. They identify shapes, locate shapes on the faces of solids, sort real objects and explain the sorting rule, and...
Curated OER
Lighthouse Geometric
Students identify the types and characteristics of geometric figures. In this lighthouse geometric lesson plan, students review shapes that represent plane or solid. They select items that could be used to construct a lighthouse...
Curated OER
Geometry Gymnastics
Students identify shapes and manipulate 2 and 3 dimensional objects. They view objects from different perspectives and review relative positions (near, far, between). They sing a shape song.
Curated OER
Our Geometric World
Third graders explore the attributes of polygons. In this geometric shapes lesson, 3rd graders review quadrilaterals, squares, rectangles, triangles, pentagons, hexagons, and octagons in order to create hanging polygons. Students then...

Recognize Squares
In this observation of squares worksheet, students identify the square figures. In this coloring worksheet, students identify six squares.
Curated OER
Are you in Golden Shape
Students solve and verify the solution for unknown measures. In this geometry lesson, students identify the properties of circles. They use the arc, angle and segment relationship to find the missing measures.
Curated OER
A Cloak for the Dreamer
Students identify the number of sides and corners of plane figures. In this geometry lesson, students read the book A Cloak for the Dreamer and identify the ways shapes fit together. Students review shapes and identify the sides and...
