Curated OER
Understanding Reflections by Paper Folding
Students investigate reflections and rotations. In this geometry lesson plan, students perform hands on experiments as they study reflections in the axis and over a line. They investigate human factors and work physiology, relating it...
Curated OER
Investigating Nets and Polyhedra
Fifth graders create a net for a given polyhedron. They determine the corresponding polyhedron for a given net. Students investigate several polyhedra (cube, tetrahedron, and one of their choosing) and their corresponding nets. They...
Curated OER
Fractals
Students explore the concept of fractals. In this fractal instructional activity, students use applets to explore Koch's Snowflake, Sierpinski's Triangle, and other fractals. Students develop these concepts through exploration and...
Curated OER
Arithmetic Artistry
Students create a classroom quilt that illustrates the many unique ways that students use math skills.
Curated OER
Make a Box
Pupils use specific dimensions to create a box. In this geometry lesson, students analyze the different properties of two and three dimensional shapes. They make conjectures and use it to solve problems.
Curated OER
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.
Curated OER
Tangram Tantrums
Students discuss tangram vocabulary, and act out slide, flip, and turn. They observe tangram puzzles on a web page, and solve their own tangram puzzles.
Curated OER
Faces, Vertices, Edges
Students identify the parts of three dimensional objects. In this geometry instructional activity, students find the number of faces, edges and vertices. They differentiate between prisms and polyhedra.
Curated OER
Terrific Tessellations
Pupils explore tessellations that are found in nature and everyday objects. They observe the works of M.C. Escher. Students create their own tessellations using pencil and paper.
Curated OER
Designing a Quilt Pattern
Students create and color a one-patch quilt design based upon a regular hexagon. They examine quilts and photos of quilt designs, read a handout, and complete their quilt design on a worksheet.
Curated OER
Making Parallel Lines
Students differentiate between parallel and perpendicular lines. In this geometry instructional activity, students make conjectures and apply it to solve real life situations. They collect data and make predictions based on the data.
Curated OER
Angles Lesson Plan
Students stud angles, and then play the "What's Your Angle?" game. They complete at least 10 computer generated problems from the Angles Applet.
Curated OER
Ship Shape
Second graders explore shapes and create a Silly Shape book. Students recognize that shapes have certain properties and be able to define them. Example, a triangle is any three-sided shape. Students' job is to make a picture on...
Pennsylvania Department of Education
Creating Polygons
Learners describe, make and compare polygons. In this creating polygons instructional activity, students identify properties of quadrilaterals and describe common features of two dimensional shapes.
Curated OER
Making Tangram Pieces by Folding Paper
Third graders follow directions to make a set of tangram pieces. After reading a story, they compare and contrast the differences between two-dimensional shapes. To end the lesson plan, they use the tangram pieces to create their own...
