Science Friday
Wind Power
Blow away the competition with a lesson about wind power and turbines. Groups build windmills to test how the size of blades affect the amount of work done. The scholars build a variety of blades and collect data on how each type...
Bytes Arithmetic
Geometry Pad+
Graphing paper, pencil, ruler, protractor, and compass, all get replaced or supplemented with this dynamic geometry application. Here, you can create, move, and scale many different shapes, as well as, explore and change their properties...

Capture the Circle (A Fraction Game)
Fourth graders compare and order fractions in a fraction game activity. In this fraction game lesson, 4th graders play a game that requires them to add fractions with like denominators and compare fractions. Students create posters where...
Curated OER
Noun/Adjective/Subject/Verb Agreement
Students create a wheel from construction paper to use to create sentences. The wheel consists of four concentric circles, beginning with the largest being 8 inches in diameter. Each circle represents one part of a sentence. Students...

Show Me!
Students analyze and interpret graphs. In this graphing activity, students view a video and construct their own graphs (line, circle, bar) from given sets of data.
Curated OER
Product of Chord Segments
Students creating chords intersection using circles. For this geometry lesson, students create visuals of chords ad their properties using Cabri technology. They measure the chords and explore the relationship among chords.
Curated OER
Star Master Viewer
Learners construct the viewing tubes by cutting along the designated line shown on the template, rolling the paper into a tube, and taping the tube securely. Next they cut out the cardstock circles - the StarCards cutting on the outside...
Curated OER
Optical Illusions
Students view, identify, and construct four optical illusions. In this optical illusions lesson, students are introduced to four types of optical illusions. They construct their own illusions.
Curated OER
Discovering The Ratio Pi And The Diameter
Students relate the ratio of Pi to the diameter of a circle. For this geometry lesson, students investigate the relationship of the chord of the circle the the number Pi. They define ration, chord, circumference and diameter and find...

Concurrent Lines, Medians and Altitudes
In this geometry worksheet, students construct angles and identify medians and altitudes. They use a compass and protractor to perform heir construction. There are 28 questions.
Curated OER
Event in Time
Students, after describing and identifying a variety of major consequences and sequences of major historical events and developments in American History, create a mobile on a specific event in history. They follow specific instructions...
Curated OER
My Weather Dial
Students construct a weather dial. For this weather lesson, students examine different types of weather and design a weather dial for use during the daily math meeting.
Curated OER
Inscribed Right Triangles
Learners calculate the measurements of the inscribed angles of a triangle. For this geometry lesson, students relate the hypotenuse of a right triangle and the diameter of a circle to each other. They calculate the diameter of a circle...
