Curated OER
Mathematical Models with Applications: The Sounds of Music
Students use an electronic data-collection device to model the sound produced by a guitar string. They identify the graph of a periodic situation and use the graph to determine the period and frequency of sound waves.
Curated OER
Similar and Congruent Triangles
Students create and classify different types of triangles using an online geo-board. They explore the concepts of similar and congruent as they discover how to draw similar and congruent triangles.
Curated OER
What on Earth is Greater Than?
Students compare things that are greater than, less than, or equal to, compare the Earth to other planets, and list planets from greatest size to smallest size.
Curated OER
Fun With Symmetry
Learners manipulate shapes to find multiple lines of symmetry. They use color to visualize the lines of symmetry.
Curated OER
Tango's Story
Fifth graders listen to "Grandfather Tang's Story" and use tangram pieces to create animals described by the main character.
Curated OER
Mobile-ize
Second graders, using a minimum of four space figures, create a mobile. They use a "Draw" program to first plan out their figure.
Curated OER
Exploring Arrangements of 2, 3, 4, and 5 Cubes
Students construct models of various tricubes, tetracubes, and pentacubes that are possible, classify n-cubes into different groupings, and draw these figures on isometric dot paper giving true perspective to what they visualize.
Curated OER
Properties of Fractals
Students build a working definition of regular fractal, look carefully at the concepts of dimension and scale, and are introduced to logarithms. They solve simple exponential equations for the exponent both by trial and error and using...

Properties of Fractals
Young scholars build a working definition of a regular fractal, they measure the concepts of dimensions and scale, they explore the concept of a logarithm and they attempt to solve simple exponential equations for the exponent both by...
Curated OER
Pythagorean Theorem Proof
Tenth graders investigate the Pythagorean Theorem. Then they type up a formal paragraph proof of a proof of their choice.
Curated OER
Geo Jammin' - Day 3, Lesson 9: Attribute Attitude
Second graders read poetry and build their vocabulary through use of the puppet Geo George.
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
Tantalizing Tessellations - Lesson I
Students complete a chart (KWL) as a pre-assessment, study the history of tessellations (tilings), investigate the properties of tessellations, and make and evaluate photographs of "found tessellations" for a PowerPoint/HyperStudio...
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
The Tiled Courtyard
Fifth graders use the guess and check technique to solve a problem involving transformations. They work with a grid and criteria provided by the teacher to solve a sequence with black and white rows.
Curated OER
Analyzing 3-D Shapes and 2-D Representations
Students can analyze 3-D objects better with actual physical models and by also drawing 2-D representations of them.
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.

Pbs: Toothpicks: Patterns in Geometric Shapes
How can you describe the pattern made by a growing triangular shape? This interactive exercise focuses on using what you know about pattern recognition and completing a table so you have data you can use to graph the coordinates on a...
PBS
Pbs Learning Media: Toothpicks: Patterns in Geometric Shapes
This interactive exercise focuses on determining probabilities associated with repeated coin tosses and building tree diagrams to take math out of the classroom and into the real world.
