Intended for beginners to geometry, an area of a rectangle problem has scholars draw out the units within the shape. They segment it into four rows and six columns to determine how many squares the rectangle is made of and, eventually,...

Students discover how to use various tools to measure and draw angles. With protractors, they classify angles according to angle measure, identify vertical angles, and perform angle additions. For their final project, students create...

Students learn the basic definitions of a quadrilateral, parallelogram, rectangle and square and explain the relationship/classification process between them.

Students write an original diamante poem about a shape of their choice. They examine how to write a diamante poem, and select a shape and write a poem using Microsoft Word software.

Students explore angle relationships and measure angles with a protractor by hand and online. They explore various websites and complete online activities and complete a worksheet.

Students look at the geometry in an artwork. In this art history/geometry lesson plan, students research the artist Charles Sheeler and look at his painting Stacks in Celebration. They find the different types of lines, angles, and...

Students examine a chart that lists the main characteristics of polygons and 3 dimensional figures. They make examples of the polygons and figures using pretzels and gum drops showing how the gum drops are vertices and the pretzels are...

Learners listen to a story involving Tangram pieces. Students use Tangram pieces to complete shapes using an outline of a design.

Students identify attributes in real-life objects and models of solids and connect these attributes to characteristics of shapes such as circles, triangles, squares, and other rectangles. They discuss the ability of the object to roll,...

Students observe geometric relationships in buildings and structures. They reason why structures are constructed in a specific way by applying geometric concepts. They construct a shelter using their geometric knowledge.

Students study how to graph ordered pairs on a coordinate plane. After a teacher demonstration, students work together to complete problems. They explain and share their answers. As an activity, they solve a mystery story about the...

Fifth graders explore basic geometric terms. Pupils draw a physical picture of a scene that illustrates at least five geometric terms. Partners exchange drawings and locate the illustration of geometric terms in the drawing.

Students create tessellations with computer software while applying their knowledge of reflections, rotations, and translations.

In this composite figures worksheet, students solve 11 short answer problems. Students find the area of figures composed of various polygons. Students find the area of each figure given a sketch of the figure with various measurements...
