Congratulations, you've just hit the word problem jackpot! Covering an incredible range of topics from integers and fractions, to percents, geometry, and much more, this collection of worksheets will keep young mathematicians...

By mounting a light bulb on a stand and a PV cell on another, physics apprentices experiment with the angle of incidence. Their goal is to determine the optimum angle for collecting solar energy. The use of a scientific calculator...

How can we identify shapes in the Universe? High schoolers will compare and contrast elliptic and hyperbolic geometry. They will also explore one possible way to measure the curvature of the Universe, namely, by measuring the sum of the...

The roots metro/meter and therm are the focus of a vocabulary building presentation that includes concise definitions, color-coded examples, and opportunities for guided and independent practice. Part of a series of roots and affixes...

There are many different ways to show a proof of the Pythagorean Theorem.  Here is a nice hands-on paper cutting activity that shows a graphic representation. You can even challenge your young Pythagoreans to come up with their own...

Although this was written to accompany a specific textbook, the information can illustrate wave motion for any advanced level physics course. The slides are simple, use plain but colorful fonts, and include diagrams and pictures to...

Scholars view the video, "Donald Duck in Mathmagic Land," and discuss examples in nature which have proportions of the golden ratio. They measure and record different body lengths from a worksheet and convert the ratios to equivalent...

In addition to the catchy title, this lesson plan provides upper graders an opportunity to more closely scrutinize the attributes of plane figures. In particular, they focus on the similarity of different shapes. Both whole-class and...

Learners find the area and perimeter of regular polygons and composite figures and examine the effect on the area and perimeter of a figure if the dimensions are multiplied by a constant. The nine page worksheet contains thirty-seven...

Through the examination of the relationship between the lengths of the sides of a triangles high schoolers will learn the classification of triangles (acute, right, or obtuse).

This detailed presentation starts with a review of using key components to graph a line. It then quickly moves into new territory of taking these important parts and teasing them out of a word problem. Special care is...

Mark off the length of the radius around the circle. Using a compass, the presenter shows how to construct a regular hexagon in a circle. Pupils see how triangles formed in the hexagon are equilateral, allowing for the construction to...

It's a piece of pizza! Pupils learn about a sector of a circle as a slice of the circle and determine how to find its area. Scholars continue to find out how to calculate the segment of a circle based on the sector's area. At the end,...

Individuals show what they know about the geometric representations of complex numbers and linearity. Seventeen questions challenge them to demonstrate their knowledge of moduli and operations with complex numbers. The assessment is...

Extend young mathematicians' understanding of area with a geometry lesson on trapezoids. Building on their prior knowledge of rectangles and triangles, students learn how to calculate the area of trapezoids and other...

Historians have proven that as early as 1497 skilled navigators were using a kamal to sail across oceans. Scholars learn about navigation tools and astronomy before building their own kamals. They then learn how to use it to determine...

This unit covers the basic trigonometry including understanding radians, how to convert between radians and degrees, the area of a circle subtended by an angle, basic properties and graphs of sine, cosine, tangent, and solving...

In this trigonometry instructional activity, high schoolers solve 15 triangle problems.  Students use the law of sines and law of cosines to find the missing angles and side lengths of a triangles.

Students study what makes Earth warm and explore how different locations on the planetreceive different amounts of solar energy based on the intensity of the sun's rays. They calculate light intensities and compare the amounts of light...

Students define the laws of sine as it relates to a right triangle. In this trigonometry lesson plan, students identify the properties of sine to help then find mixing sides of a right triangle. They also solve for the missing angles.

Students measure the perimeter and area of their polygons. In this geometry instructional activity, students calculate the volume and area using the correct tools. They calculate the time and temperature and the perimeter and side...

Building on young mathematicians' prior knowledge of three-sided shapes, this lesson series explores the defining characteristics of different types of triangles. Starting with a shared reading of the children's book The Greedy...

Concepts are only valuable if they are applicable. An informative resource uses concepts developed in lessons 26 and 27 in a 36-part series. Scholars write equations and solve for missing side lengths for given right triangles....

Young mathematicians identify different cases of intersecting secant lines. They then investigate the case where secant lines meet inside a circle.
