The Geometry of Letters
Use the alphabet as a tool for teaching your class about geometric figures. Break apart capital letters into line segments and arcs. Classify angles as right, acute, or obtuse. Identify parallel and perpendicular lines. An excellent...

Using Symmetry to Create Corporate Logos
Young mathematicians investigate the use of symmetry in graphic design. After first learning about reflection, translational, and rotational symmetry, children use this new knowledge to identify symmetry in letters of the alphabet and...

Geometry
Fourth graders explore symmetry and congruent figures. They draw letters of the alphabet that have symmetry, draw congruent figures, draw figures on dot paper, and complete three worksheets.

Making and Describing Shapes
Explore the concept of creating and describing 2D and 3D shapes. Using geometry your scholars will describe the attributes of shapes and their properties. They explore and discover what happens when you combine shapes and then take...
Curated OER
Folding Shapes; Are the Sides the Same?
Second graders explore geometry by experimenting with fold-ables. In this geometric shapes lesson, 2nd graders utilize cutout shapes from construction paper which they experiment with by folding. Students examine the symmetry and...

Lesson Plan Two: Polygons
Learners explore the concept of polygons on a two-dimensional plane. They identify polygons in everyday life and draw different polygons according to their classification. Using a geoboard and geobands, they consrtuct polygons and even...

Rotation
Rotate this resource into your lesson plans. Scholars rotate polygons in the coordinate plane by multiples of 90 degrees. They then compare the original and new figures to develop conjectures about coordinate points after rotations.

Identifying Lines of Symmetry
Young scholars calculate the lines of symmetry using polygons. In this geometry lesson, students graph, compare and estimate using collected data. They identify different attributes to the polygons based on their sides.

Rectangles and Trapezoids in the Coordinate Plane
Students determine the missing vertices of quadrilaterals. In this rectangles and trapezoids lesson, students examine the characteristics of quadrilaterals. They identify the missing vertices of a quadrilateral on a coordinate plane.
Curated OER
Quadrilaterals in the Coordinate Plane
Young scholars find the coordinates of the vertices of special quadrilaterals placed in the coordinate plane. They find the coordinates of missing vertices of squares and parallelograms.

A World of Symmetry
Middle schoolers identify lines of symmetry. In this symmetry lesson, students create objects and identify their lines of symmetry. They answer questions about lines of symmetry. Middle schoolers cut shapes out of cookie dough and...
