Curated OER
The Quadratic Formula
Students solve quadratic function by completing the square. In this algebra lesson, students use the quadratic formula to factor quadratics and find the roots. They graph the parabola and identify its properties.
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
Blindfolded Building
Students build a Lego design and then work with a partner to reproduce that design. They guide the building of the reproduction by description only and then check their work.
Curated OER
Tessellations Lesson
Fifth graders demonstrate their understanding of tessellations by watching a teacher prepared Powerpoint presentation and completing an activity. The students work independently to identify tessellations.

Family Activity: Triangles and Quadrilaterals
In this triangles and quadrilaterals worksheet, students solve 7 short answer problems. Students find objects around the house that are constructed from triangles, parallelograms, trapezoids, squares, rectangles. Students sketch the...
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
Equilateral Triangles
Students examine the attribute of equilateral triangles. In this equilateral triangle lesson plan, students examine a number of paper triangles to determine how they are classified. They determine how triangles are depicted in Navajo rugs.
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
Measuring Supporting Structures
Students calculate the volume of the Pantheon's columns and estimate changes in weight given different parameters.
Curated OER
Introduction to Plates, Axles, and Gears
Students are introduced to the function and design of the following Lego pieces: beams, bricks, plates, axles, tires, hubs and bushings. They then work with a partner to build something using only these pieces.
Curated OER
The Mandelbrot Set
Students explore the Mandelbrot Set. They are introduced to the concept of a complex number and function in order to motivate the discussion of Julia and Mandelbrot sets. Students investigate fractals and how they are built.
Curated OER
Learning by Sorting
Students sort Lego Duplo pieces after determining the attributes to classify them by. They work in pairs to sort a group of Duplo pieces and explain their process to others.
Curated OER
Impossible Graphs
Learners distinguish between possible and impossible graphs of functions, and to learn why some graphs are impossible. They have practiced plotting functions on the Cartesian coordinate plane
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
Angles and Parallel Lines
Sixth graders draw parallel and intersecting lines to observe and examine the characteristics of alternate interior angles, vertical angles, corresponding angles, and supplementary angles. Through observation, they discover the...
Curated OER
Minerals
Students explore the concept of minerals. In this minerals activity, students discuss how cooling affects the size of crystals. Students discuss how the structure of minerals is a tetrahedron. Students discuss the structure of silicates...

Geo Jammin' By DeSign - Day 3, Lesson 12: Jammin
Learners review definitions of word wall words using songs, movement and sharing.
Curated OER
Calculating the shortest distance between two points
Eighth graders find the length of the third side of a right triangle.
Curated OER
3-D Beginning Graphs
Students explore the concept of big and small. They collect objects from the classroom, sort them by size, and create a graph using Duplo stacking blocks.
