Expand trigonometric ratios beyond right triangles. Pupils start with a review of trigonometric ratios and then take a look at angles in standard position to determine their measurements. Scholars discover how to find coterminal angles...

What is the universal breakfast? The resource includes two activities, the first one observing oatmeal to understand the texture of the universe. Then, scholars measure raisin bread dough before and after it rises to represent the...

Learners examine objects and find their volumes using geometric formulas in the 21st installment of this 25-part module. Objects take the shape of truncated cones and pyramids, and individuals apply concepts of similar triangles to find...

Young scientists investigate methods of comparing standard and metric units with a technology-enhanced lesson that builds a connection between conversion ratios and the corresponding units. The simulation allows learners to...

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...

The news reports on rising sea level, but how do scientists measure this rise? Scholars use NOAA data including maps, apps, and images to work through five levels of activities related to sea level. Each level in the series adds a new...

Here's another great way to learn from the past. Released free-response questions provide a look into how concepts measured on the 2005 AP® Statistics Exam on Form B. Teachers and pupils review questions that cover concepts such as...

Use graphs to interpret life in 136 counties. Pupils analyze histograms and describe the shapes of the distributions of data collected from several counties on different aspects of life. Scholars make predictions on the difference in...

It may be tricky for a young mind to conceptualize that less than 1% of all water on earth is useable for humans to drink. Simulating the amount of fresh water available on earth by removing measured amounts of water from a five-gallon...

Students read an article at CNNfyi.com about Mad Cow disease. They identify and explain bovine spongiform encephalopathy and Creutzfeldt-Jakob disease. They formulate ways to combat mad cow disease.

Save those precious minutes and hours spent planning math lessons with this mini-unit on telling time. Offering a series of engaging hands-on and collaborative learning activities, these three lessons teach children how to read...

While pupils design their own lab experiments, they will not form a new species. Scholars take their materials and design an experiment regarding reaction rates. 

Six word problems provide practice for young geometers to review angles, the angle a of straight line, circles, right angles, and others. I like the approach of these questions; they require thinking and explaining, not just computation.

Learners solve 14 word problems and 25 weight conversions.

How do cohesion and adhesion work together? The third installment of a nine-part series teaches young scientists the difference between adhesion and cohesion. They also learn how cohesion and adhesion work together to cause capillary...

Triangle centers and the segments that create them easily become an exercise in memorization, without the help of engaging applications like this lesson. Here the class investigates the measure of center that is equidistant to the three...

In this chemistry worksheet, students examine a concept in science and then use the knowledge in application by conducting an experiment.

How can we accurately estimate what the economy should produce now and in the future? Have your pupils tackle this question as they learn about real versus potential GDP and as they review data regarding the output gap in...

Let your use of the resource be in proportion to its usefulness. Pupils investigate similar triangles by measuring side lengths and considering given angle measures. The results of the investigation help develop generalizations about...

You're only 10 minutes late? Do you know how much the universe has expanded in those 10 minutes? Scholars graph supernovae based on their redshift and see if the results verify Hubble's Law. If it does confirm it, the universe is...

Let's see what the class learned! The last installment of the 23-part Pre-calculus module consists of nine assessment questions designed to measure a specific portion of a standard in the unit. Learners demonstrate their understanding of...

A variety of word problems help your learners examine the ways that they find solutions. Each question provides opportunities to add, subtract, and multiply time, measurements, and money.

Electronic engineering hopefuls get hands-on with hand geometry and the technology of biometrics. After taking the appropriate measurement on their hands, they configure their personal hand geometry codes and compare them to classmates....

This cool lesson plan is ideal for elementary engineers or physical scientists, especially when learning about heat transfer and insulation. After reading a page of background information, engineering teams collaborate to design and...
