As they investigate scaling figures and calculate the resulting areas, groups determine the area of similar figures. They continue to investigate the results when the vertical and horizontal scales are not equal. 

It's a neat idea, but the task of designing a system for filling jars with consistent specific amounts of a product may be a little out of reach, especially for younger pupils. Intended as an engineering design lesson, this may be better...

Antarctica is a big place, large enough to provide ample opportunities to learn about math. A two-week unit teaches middle school mathematics concepts using project-based learning. The resource covers functions, geometry (area,...

Understanding how functions transform is a key concept in mathematics. This introductory instructional activity makes a strong connection between the function, table, and graph when exploring transformations. While the resource uses...

Decide which concentration of mixtures is the strongest. Pupils use tables to compare ratios involved in mixtures. They use two methods to make the comparisons — by finding equivalent values within the tables or by comparing the...

Right triangles are so special! Use special right triangles to discover the trigonometric ratios. Pairs construct special right triangles and find the values of the ratios of the sides. In the process, they discover the ratios stay the...

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'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...

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...

Develop a formula based upon numerical computations. The 31st part of a 33-part unit has the class determine the formula to convert a temperature in Celsius to a temperature in Fahrenheit. They do this by making comparisons between the...

It's a balancing act! Pupils balance pennies on a ruler to create a physical representation of a dot plot. The scholars then find the distances of the data points from the balance point, the mean.

Present your pupils with some moral dilemmas to examine. The scenarios, which learners rank by seriousness individually and then in groups, require learners to think about right and wrong.

Using the natural pH indicator of red cabbage juice, groups determine the pH of different everyday liquids. As they work, pupils gain an understanding of pH that may help deal with contaminants in the water supply. 

Remember the Alamo! Scholars investigate the Battle of San Jacinto during the Texas Revolution. Using models, maps, quotes, biographies, and the Oath of Allegiance, the Alamo comes to life as the stories of those who fought and died in...

Bubble, bubble, boil and trouble! What causes common substances like baking soda and vinegar to react the way they do? Welcome your junior chemists to the wonders of acid-base chemistry using a comprehensive and fun...

Preparing for an AP test is about more than bubble sheets and memorization. The two activities in this resource require a direct application of skills learned throughout an AP Physics course.

Agriculture surrounds us every day; incorporate measuring tools into a study of Oklahoma's agricultural industry! Small groups read an informational text (included) before visiting stations where they investigate prices of various...

Is there a relationship between hand span width and height? Statisticians survey each other by taking measurements of both. A table that can hold data for 24 individuals is printed onto the worksheet, along with questions for analysis....

Transform studying about veterans in a textbook to personal interviews with veterans in the community. Four varying lesson plans make up an entire unit or individualized learning based on your class's needs. Exercises include researching...

Your learners combine their knowledge of real and imaginary numbers and matrices in an activity containing thirty lessons, two assessments (mid-module and end module), and their corresponding rubrics. Centered on complex numbers and...

Continue the study of transformations with an examination of horizontal stretches, shrinks, and reflections. Individuals use the same process used in parts one and two of this series to examine horizontal changes. The resource also...

Explore linear programming on a website game. Partners solve a real-world problem by setting up an objective function and a linear inequality. They graph their results on chart paper and also using a calculator before presenting their...

At the end of this activity, your number crunchers will have a better understanding as to how to describe graphs of velocity versus time and distance versus time. It is easy for learners to misinterpret graphs of velocity, so have them...
