African Ceremonial Masks
Fourth graders examine and discuss the purposes and traditions of African ceremonial masks. They design and create African ceremonial masks using various materials.
Curated OER
Translations, Reflections, and Rotations
High schoolers are introduced to the concepts of translation, reflection, and rotation. They practice translating, reflecting, and rotating two-dimensional objects on the coordinate plane. students use computers to learn about the three...
Curated OER
Slope Right Up
Learners use triangles to find the length and slope of each side. After connecting the vertices, they add points based on their specific instructions. They use the Pythagorean Theorem to complete a worksheet to end the lesson.
Curated OER
Who's In The Fact Family?
Students study related addition and subtraction facts. In this math lesson, students use related addition and subtraction to solve problems. Students use manipulatives to explore fact families.
Curated OER
Let the Matrix Do It
Students create a matrix of the vertices of a triangle and produce new matrices that dilate, translate, rotate, and reflect the original triangle. After multiplying each matrix by a new scale factor, they graph the new matrix and...
Curated OER
Transforming Triangles
Sixth graders examine how to graph translations (slides) and reflections (flips) on a coordinate plane. They practice the slides and flips kinesthetically and apply it to a worksheet working with triangles.
Curated OER
Kindness Compliments
Students write compliments for the staff at their school. In this compliments lesson plan, students demonstrate kindness by anonymously writing and taping compliments to people's doors around the school.
Curated OER
Mirror Tool
Students define properties of polygons. In this geometry lesson, students differentiate between similar and congruent polygons. They identify and use the properties of solids to solve problems.
Curated OER
Terrific Tessellations
Students 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
Friendship Quilt
Third graders name different kinds of shapes and then discuss what they know about them an what they would like to learn using a K-W-L chart whole group. They listen to the book, THE GREEDY TRIANGLE and then retell it to the class. They...
Curated OER
Tessellation Quilt Squares
Fifth graders design a "quilt block" that has a tessellating pattern to help create a class tessellation quilt. They describe relationships between two- and three-dimensional shapes and analyze attributes and properties of geometric...
Curated OER
Pattern Using Unit Cells
Students explore the pattern of the unit cell. In this science lesson, students color the unit cells on a worksheet and create a pattern using unit cells.
Curated OER
Odd Thing Out
Students listen to the math problem provided and work in groups to solve. They think about the objects and write down their information in a table. Class construct the table on a large piece of paper that can be put on the wall after the...
Curated OER
Building Paper Bridges
Learners construct a bridge that can hold 100 pennies. In this math lesson, students evaluate the strength of their bridges. They predict how much weight a bridge can hold based on its design.
Curated OER
Similar or Not?
Fifth graders define the meaning of similar and congruent using concrete objects. They make similar and congruent figures using geoboards. They draw their figures on dot paper, and color their designs.
