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.

Integrating Art Into Other Content Areas
Here are some ideas to help add an art lesson to every math, science, social studies, or language arts unit.
Curated OER
Measuring the Area of Polygons
Fourth graders use pattern blocks to explore areas of polygons. They explain that the answers to the area of the same polygon vary according to the units of measurement used. They visualize how different units of measurement can be used...
Curated OER
Mathematics of Ornaments and Architecture
Students study African traditional architecture. They examine how African ornaments, wall painting and motifs use geometric shapes to express and explain the culture.
They discuss the ornaments and architectural designs in the setting...
Curated OER
Pattern Matching
First graders examine how to determine the lines of symmetry in pictures, shapes, and patterns by completing the lessons in this unit. They make patterns that show a line of symmetry and describe it using their own language.
Curated OER
Lesson Exchange: Polygons (Middle, Mathematics)
Students discover the relationship between the sides of a polygon and the number of diagonals that can be drawn from one vertex, the number of triangles that those diagonals form, and the sum of the interior angles of that polygon.
Curated OER
Family Activity: Triangles and Quadrilaterals
In this triangles and quadrilaterals worksheet, students solve 7 short answer problems. Kids find objects around the house that are constructed from triangles, parallelograms, trapezoids, squares, rectangles. Students sketch the object...
Curated OER
Using the Variation Approach
Young scholars explore and explain geometrical applications, and how to apply these applications to real life.
Curated OER
Precision Tools
Students discuss the appropriateness of using a specific tool to measure and define an object. After measuring the area of their classroom and the objects in it with the appropriate tools, they create a floor plan that makes the most...
Curated OER
Refining and Reasoning Behind Scale Drawings
Students discuss accuracy and the need for it in blueprints in order to create the final project. They further refine and perfect drawings as part of the school drawing project. Students create a blueprint for the new school building...
Curated OER
Geo Jammin' By DeSign - Day 3, Lesson 12: Jammin
Students review definitions of word wall words using songs, movement and sharing.
Curated OER
Geo Jammin' By DeSign - Day 5, Lesson 25: Geo Jungle
Students search the school grounds for examples of symmetry in nature. They bring examples back to the classroom and write about them.
Curated OER
Tiling the Plane
Students use pattern blocks and triangular grid paper to review shape names, be introduced to the concept of a tiling of the plane, and determine which pattern blocks tile the plane. They are asked: "Have you ever seen a floor or a wall...
Curated OER
Minerals
Students explore the concept of minerals. In this minerals lesson plan, students discuss how cooling affects the size of crystals. Students discuss how the structure of minerals is a tetrahedron. Students discuss the structure of...
