Prime or composite, that is the question. Teach your class how to find the answer with this step-by-step presentation that defines and provides examples of each type of number. When addressing larger numbers, divisibility rules are...

Before loaning a friend money, what factors would you consider and why would you lend it? Your young economists will face questions like these in a instructional activity on banking, profit, risk, and reward, which includes the...

Have your young scientists questioned why plants grow a particular way? Through this learning opportunity, scientists gain firsthand knowledge about how plants develop and various factors that affect rates of growth as they bring plants...

What does it mean to be a good steward? Middle school environmentalists learn to care for their state's waterways through research, a guest speaker, and poster activity. Groups must locate and learn more about a river basin and the human...

Count on the scale to enlarge a figure. The video shows how to create an enlargement given a scale factor and a center of enlargement. The presenter multiplies the vertical and horizontal distance by the scale factor to find the new...

Scale the challenge of learning about ratios and scales. Young mathematicians learn to incorporate fractional measurements when considering scales and scale factors. They use an interactive to investigate the concept and critically...

Tip the scale in your favor when learning about scale factors. After viewing a video clip of a learner trying to determine the scale factor of the areas of two rectangles, scholars consider how changing the dimensions of a rectangle...

Salmonella poisoning impacts over 200,000 people in the United States each year. Scholars learn about the growth of these bacteria using multiple approaches. Then they apply the same growth calculations to endangered species and think...

Currency exchange is a big factor in governments making economic decisions. Scholars consider various scenarios to evaluate how factors such as interest rates and private investments would affect a nation's economy using a practice test...

Middle schoolers learn how to "put stress to rest" by identifying their stress factors and the physical and emotional signs they exhibit when stressed. After the class brainstorms ways to handle these stressors, individuals commit to...

A solution will work one way or another: find solutions, or use solutions to find the function. Learners use polynomial identities to factor polynomials with complex solutions. They then use solutions and the Zero Product Property to...

Design your dream classroom. The lesson plan contains an exercise to have teams create a scale drawing of their dream classroom. Pairs take the measurements of their classroom and furniture and create a scale factor for them. To finish...

Observing plant succession doesn't have to be a decade long process. A hands-on instructional activity has groups study succession over a designated space. Learners use their observation skills to record differences in plant and soil...

Introduce infectious diseases and the epidemiologic triangle. A helpful resource describes the agent, host, and environment from the three vertices as well as the time factor, which is in the middle. Scholars complete a simple...

Young mathematicians use photos and video clips to determine if a cricket player is "in" or "out." This analysis occurs using scale factors, distance-rate-time formula, and consideration of precision and accuracy.

If you're searching for a worksheet that covers all things factoring look no further. The worksheet covers factoring out a GCF, factoring by grouping, trinomials, and difference of squares. And the best part? The answers to the...

Develop scales using tables. Pupils complete charts to show equivalent scale factors before using the completed tables to determine the sizes of scale drawings. They finish the lesson and demonstrate their understanding by completing a...

Try your hand at scale models. Scholars create a scale model of an object using a scale factor of their choice. As part of the project, they give presentations on their processes and calculations. This is the last installment of the...

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...

The United States has more per capita emissions than any other country in the world. An eye-opening simulation encourages users to explore environmental goals and factors that affect climate change by balancing different priorities....
