It's 3:30, what radian is it? Pupils create clock angles on a clock and determine the radian measure to the minute hand. They then use a conversion factor to convert from one measurement to another.

How do degrees relate to radians? The interactive allows pupils to manipulate the size of an angle in a unit circle to help see that relationship. Users determine the radian measure for given degree measures of angles, realizing the...

Convey to your pupils the importance of units, then show how to use dimensional analysis to perform a unit conversion. The math lesson includes detailed worked-out solutions to guide learners in their practice.

Forget hours, divide the day into radians instead. Class members convert the angles in a pie chart of daily activities into radian measures. They add angle measures for multiple activities then determine a relationship between the radian...

How are arc lengths and radians related? An interactive resource demonstrates the relationship as pupils create arc lengths in a unit circle and compare them to the angle measurements. Questions ask individuals to build upon this...

Challenge the young mathematicians to find the exact coordinates of a dilated point. The fifth segment in a 16-part series introduces the class to the converse of the Fundamental Theorem of Similarity. Scholars use the theorem to...

Where is a geneticist's favorite place to swim? A gene pool. Young geneticists complete hands-on activities, experiments, and real-world problem solving throughout the unit. With extra focus on dominant and recessive genes, Punnett...

Can a small change in laboratory procedures save energy? Scholars test three different methods for heating water in a science lab. Then, they calculate the energy efficiency for each and compare them to determine which uses the least...

You didn't know you'd find moles in chemistry class! Through the introduction of moles and molar volume at STP, classes see how to calculate moles using a given chemical equation. The presentation includes a short review of ions in...

Follow six steps to implement this series of metric worksheets. Here, mathematicians exhibit their knowledge of problem solving, while converting units of measurement and label their answers with the applicable unit name.

Circles are the foundation of many geometric concepts and extensions - a point that is thoroughly driven home in this extensive unit. Fundamental properties of circles are investigated (including sector area, angle measure, and...
