Area: It's What's on the INSIDE That Counts!
Second graders participate in a series of hands-on, online and multimedia activities that examine the concept of area. They view clips from the animated series Math Monsters and discuss the purpose of area and how it is used in the real...
Curated OER
"Space" Exploration
Fourth graders identify the attribute of volume of an object. Units of measurement are reviewed and utilized in this lesson.
Curated OER
"Graphing Your Motion"
Students study the concepts of motion, velocity, and acceleration through graphing their own movement using LoggerPro. They explain the difference between speed and velocity using the weather vane example. They discover the difference...
Curated OER
Bird Eggs
Students perform an experiment with different types of bird eggs to determine what factors make them strong and able to stay on a cliff without rolling off.
Curated OER
Ratios in Right Triangles
Learners calculate the sides of right triangles in this trigonometric ratios activity. They use Cabri Jr. software and TI-83 or TI-84 calculators to find the side lengths and their ratios to each other for various triangles. The provided...

Angles: Angles, Angles, Everywhere
Young scholars practice estiminating and measuring angles. After watching a short video, they identify angles in objects in the classroom and their homes. In groups, they participate in activities in which they are given a scenerio and...
Curated OER
Secants, Tangents and Arcs
Students identify chords and angles. In this geometry lesson, students calculate the length of the chords inside and outside of-the circle. They differentiate between tangent and secant lines.
Curated OER
The Domino Effect
Students model the transmission of neural impulses with dominoes. In this nervous system lesson, students construct a device with dominoes. They use the device to model the way a nerve impulse is propagated from dendrite to axon.
Curated OER
Proving Pythagoras
Students prove the theorem of Pythagoras. In this Pythagorean Theorem lesson, students define the different parts of a right triangle. They use the Pythagorean Theorem to solve for the missing sides and angles of a right triangle.
Curated OER
Investigating Segments in a Triangle
Pupils investigate segments in a triangle by constructing a triangle using Cabri Jr. They construct segments within the triangle that lie on the midpoints of the triangle's sides. Learners then compare the slope of base of the triangle...
Curated OER
Woody Sine
Learners explore the concept of sine. In this sine lesson plan, students create a sine graph from tooth picks. Learners create a unit circle with tooth pick length radius. Students then take the tooth picks from the unit circle and put...
