"Geometry With Quilts"
Fifth graders examine the geometry of quilts. They discuss the history of quilting, design two nine-patch squares, exchange one design on an Internet bulletin board, and construct a hot pad that is quilted.
Curated OER
The Geometry of Indigenous Art
Young scholars examine the concepts of symmetry, rotations, reflections, translation, dialations, and tessellations and apply them to indigenous art. They also do Internet research and create artwork (painting, pottery, computer graphic...

What's The Point?
Students solve word problems using the correct math symbols. For this algebra lesson, students use the TI calculator to graph their equation and analyze it. They find the line of regression and use to draw conclusion.
Curated OER
Elmer the Elephant
Learners read "Elmer" by David McKee. They answer comprehension questions and discuss how Elmer looks and how he is different from the elephants they see in the zoo. They complete a project in which they celebrate their individual...
Curated OER
Hurricane Tracking
Students access the Internet to find information on current hurricanes. They get locations, speeds, and air pressures and then plot the location of the hurricane on a hurricane-tracking map. They also access the FEMA website to solve...
Curated OER
Geometry: Classifying Quadrilaterals
Students use construction technology to identify and find relationships between the attributes of various quadrilaterals. They make and test conjectures about the distinguishing properties of parallelograms, rectangles, rhombuses,...
Curated OER
Lesson Exchange: Polygons (Middle, Mathematics)
Pupils 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
Mosaic Pavement Panel
Young scholars analyze Mosaic art and identify the tessellation process. In this Mosaic art lesson, students read information about Mosaic art and the tessellation process. Young scholars compare mosaics from various civilizations and...
Curated OER
The Art of the Quilt
Students examine why fabric was first sewn in layers and how it was used. They identify, compare and make 3 different fabric design types which will become a basis for looking at the quilts created by African Americans. They begin the...
Curated OER
What a SHAPEly Fit!
Learners identify and explore the attributes of polygons. They design and create a quilt square using polygons, and produce a class quilt.
Curated OER
Exploring Arrangements of 2, 3, 4, and 5 Cubes
Students use problem solving skills to create various models of tricubes, tetracubes, and pentacubes. They classify the cubes into various groupings and identify them as mirror images, regular arrangements, and irregular arrangements....
Curated OER
Geometry Gymnastics
Students identify shapes and manipulate 2 and 3 dimensional objects. They view objects from different perspectives and review relative positions (near, far, between). They sing a shape song.
Curated OER
Geometry Flip Book
Learners investigate the concepts of geometry that can be grouped into a flip book that can be used for teaching and review purposes. They define the differences between two and three dimensional figures. Also polygons are reviewed and...
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
Creating Tessellations
Third graders explore the history of tessellations; then use art and geometry to create an original tessellation.
Curated OER
Governor's Garden
Students review types of polygons and list several examples of each. They assume the role of a landscape artist interviewing for a job. They create sketches of their plans for six polygonal gardens and write an expository paragraph...
Curated OER
Logic
Pupils solve problems using reasoning techniques, identify the validity or non-validity of problems and use deductive reasoning for problem resolution.
