Hands-on and real-world applications are great ways to teach mathematical concepts. Creative thinkers examine how ratios are used to create scale models of buildings and structures. They practice working with ratios by looking at a map...

There has been an earthquake! Can you listen to the description of damage given by callers in order to determine the epicenter? The 11th of 20 lessons has pupils read a script of one emergency caller. The class records the information on...

Here is a challenging presentation which should be tough for even your top math learners. In it, pupils view 86 slides which take them through many mathematical concepts such as doubling, halving, decimals, word problems, and converting...

In this distance formula worksheet, students solve and complete 30 various types of problems. First, they find the exact distance between each pair of points and make a sketch of the situation. Then, students find the center, horizontal...

The U.S. produced enough wind energy in 2015 to power all of the homes in Alaska, California, Delaware, the District of Columbia, Hawaii, Idaho, Maine, Montana, Nebraska, New Hampshire, North Dakota, Rhode Island, South Dakota, and...

In this similarity instructional activity, 9th graders solve and complete 6 different types of problems. First, they complete the statement in the box shown. Then, students determine whether they agree or disagree with the statement and...

Measuring the diameter of the sun may get a little heated, but using an indirect approach can help individuals keep their cool. Learners use the reflection of the sun to measure how long it takes for it to move one diameter. Using the...

In this Olympic bar graph worksheet, young scholars pick a sport from the 2004 Olympic games and find data from the Olympic web page. They graph the scores (times, distance, or speed) and the medals. They answer questions about the...

Students collect and analyze data on a fictional cereal company's products. In this measurement lesson, students collect data from cereal boxes (weight, volume, surface area, etc.) to determine if the boxes labels correctly inform...

In this formulas worksheet, students determine the distance between two points.  They read story problems, identify needed information, write equations and solve them.  Students find the midpoint of a line.  This two-page...

Sixth graders count money.  In this money lesson, 6th graders count sets of coins and dollar bills.  During specified activities, they total orders and calculate the amont of change a customer should receive.  Students...

Here's proof that small-scale labs lead to big-time learning. Introduce acid-base interactions to middle school scientists through a microscale chemistry lab. Pupils combine a variety of solutions and use indicators to obtain approximate...

Why are acids and bases important in our daily lives? Lead the class in answering this question, among others, as they experiment with pH paper and classify where various substances belong on the pH scale. They also taste common acids...

How do computers sort data lists? Using eight unknown weights and a balance scale, groups determine the order of the weights from lightest to heaviest. A second instructional activity provides the groups with other methods to order the...

Students compare bacteria and viruses and their roles in biotechnology and bioterrorism. They outline fundamental steps of bacterial transformation and the possible selection processes to identify transformants. They discuss...

Learn about the causes of earthquakes, as well as the value of seismographs, with an informative presentation. From the Richter Scale to the Mecalli Scale, learners discover elements that make an earthquake occur.

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...

Learners investigate the relationship between the Fahrenheit and Celsius temperature scales. Given two data points, they construct a linear function to describe the relationship, find the inverse of the function, and make observations...

In a force diagram, a stick figure man in an elevator takes a ride. Physics analysts work out the force exerted on him by the elevator floor. As the acceleration changes, they draw new force diagrams and compute new force values. This...

Don't let the term, "slotted wood board" detract you from the value of this experiment. Class members tie a string to a cart and, with even horizontal force, drag it up an inclined plane. The objective is to compare the work done with...

On your mark, get set, GO! The class sprints toward the conclusions in a race analysis activity. The staggered start of the 400-m foot race is taken apart in detail, and then learners step back and develop some overall race strategy...

Rewrite a quadratic function to easily see the transformations involved. The instructional task takes a general quadratic function and rewrites it into a form that shows the translations and scaling of the parent quadratic function. The...

High schoolers create maquettes of abstract sculptures utilizing the elements of art; line, shape, value, color, space and texture and the principles of design; balance, emphasis, contrast, rhythm and movement, pattern and unity. These...
