Curated OER
Handprint Angels
Students trace their hands onto white paper and cut them out. They create a holiday art piece by adding a "head" and a "body" and then decorating them to resemble an angel. (Their handprints become the wings.)
Curated OER
Fun With Fractals
Learners use fractals to analyze nature. In this geometry lesson, students work in groups using technology and math to communicate. They identify where in the real world fractal can be seen.
Curated OER
Magical Shapes
First graders practice manipulating shapes into different locations. They see that even though shapes may look different when they are moved into different locations, the shape remains the same with the same properties. They make...
Curated OER
Understanding Fundamental Trigonometric Identities
Students are introduced to the basic trigonometric identities. Using a diagram, they discover why the parts of the unit circle as named as they are and use equations to finalize the Pythagorean trigonometric identities. They also review...
Curated OER
Flips, Slides, and Turns
Fifth graders manipulate and draw shapes to demonstrate the concept of flips, slides, and turns using letters and arrows on graph paper.
Curated OER
Origami Cube
Young scholars compare two lengths using the area of a square. For this geometry lesson, students solve problems using ratio and proportion of the two shapes. They solve equations by taking the square root of both sides.
Curated OER
Koch Snowflake
Students investigate Koch's Snowflake. In this geometry lesson, students identify the properties of creating Koch's snowflake. They solve problems dealing with fractals and patterns.
Curated OER
Fractals: Koch Snowflake
Students investigate the properties of Koch's snowflake. In this geometry lesson plan, students investigate fractals and patterns. They create Koch's snowflake using Cabri software.
Curated OER
Shapes!
Students identify five basic geometric shapes by naming them according to their defining characteristics. They draw the shapes and identify food with similar shapes.
Curated OER
M. C. Escher - Design - Math Integration
Students create a tessellations using rotation and translation. They also create a tessellation using reflection.
Curated OER
Geometry and Shapes
Fourth graders are asked to name different shapes.Four to five students to share their answers with the class. The teacher leads the discussion in geometry about the properties associated with shapes.
Curated OER
Connecting Translations, Reflections, and Rotations
Learners differentiate between translation, reflection and rotation. They explore the 3 types of transformation using Cabri Jr. and build on previous knowledge in this lesson plan.
Curated OER
Pattern Block Polygons
Sixth graders create polygons. In this shapes activity, 6th graders explore prefixes such as oct, tri, quad, pent, etc. and share their findings. Students use pattern blocks to create two different polygons and label them.
Curated OER
Platonic Solids
Students identify different types of polygons. In this geometry lesson, students differentiate between convex and regular shapes. they identify the names of two and three-dimensional objects.
Curated OER
Identify, Sort, Classify
Students identify, sort, and classify. In this kindergarten math lesson, students explore visual examples of sorting with 1 or more attributes. Students also practice solving problems that their instructors model.
Curated OER
Similarity
Students engage in a lesson that is concerned with the concept of similarity. This takes higher order thinking skills and being able to separate into categories. Specifically in this lesson they are introduced to the scale and how it is...
Curated OER
Tessellations
Seventh graders investigate geometric shapes using tessellations. For this geometry lesson, 7th graders practice tessellations using different shapes. They create different designs using tessellations.
Curated OER
Geometry Everywhere; Fractal, Math & Form
High schoolers explore fractal geometry. They do online explorations of fractals to discover applications of fractal geometry for a report.
Curated OER
May Baskets
Students create a May Basket. In this cutting and pasting art lesson, students use pictures of flowers from magazines to create a bouquet of flowers. Students cut the pictures out, past them to toothpicks and arrange them in...
Curated OER
The Trappings of Trapezoids
Students define trapezoids and their shapes. In this geometry lesson, students calculate the area of a trapezoid and a parallelogram. They use Cabri software to make investigations.
Curated OER
Trigonometric Ratios
Students measure and analyze angles. In this trigonometry lesson, students measure angles and distances use non-traditional techniques. They identify the different ratios of sine, cosine and tangent.
Curated OER
Geometric Shapes And Figures
Students compete in a scavenger hunt to find twenty-two different geometric shapes in natural objects around the school. They practice identification of each geometric shape using a handout then form small groups to search the school...
Curated OER
Geo-Critters (Geometry Critters)
Students read the book The Math Curse by Jon Scieszka and study geometry. In this geometry instructional activity, students identify geometric shapes and their properties. Students create a geo-critter.
