The world is full of patterns. Help learners quantify those patterns with mathematical representations. The first Algebra lesson in a compilation of four uses a series of activities to build the concept of patterns using multiple...

Develop conceptual knowledge of a quadratic equation and its solutions in your classes. The third algebra lesson in a series of four introduces learners to solving quadratic equations slowly. The first activity explores the zero product...

Do your pupils truly understand inverse operations, or is their understanding a little backward? Scholars learn the meaning of an equation in the second lesson of a four-part Algebra series. A series of activities begins with an...

When an organism eats, how does food become energy? Young biologists follow glucose through the process of cellular respiration to the creation of ADP using a discussion-based activity. The resource also highlights conservation of mass...

Learners calculate the pixel density of a specific cell phone using the concept of similarity. They use information from the cell phone's website to make their calculations and then compare their results to the posted information.

Puzzle your way through to a new understanding of area. Scholars learn about the area of polygons through equidecomposability, the idea that polygons that can be decomposed into the same set of pieces have the same area. By using...

Don't assume your pupils understand assumptions. A teacher resource provides valuable information on inferences, assumptions, and conditions, and how scholars tend to overlook these aspects. It focuses on regression analysis, statistical...

Teenage brains are different! Understanding that the teenage brain is still developing and thus more impacted by substance abuse is the key concept in a three-lesson high school health unit. Participants learn about how the brain and...

Why are greenhouse gases called greenhouse gases? Young Earth scientists learn about greenhouse gases though experimentation in the second installment of a 3-part series. They use lamps to model radiant energy as well...

Dive into the political breach with pupils and explore the reasons for political polarization. Using clips from C-SPAN that include discussions from reporters and scholars, class members consider what is causing the political fault lines...

We know theorems about circles—now what? Class members prove a theorem, with half the class taking the case where a point is inside the circle and half the class taking the case where a point is outside the circle. The lesson then...

The second day of a two-part lesson on motion introduces the class to circular motion. Pupils learn how to incorporate a time parameter into the rotational matrix transformations they already know. The 24th installment in the 32-part...

The fifth portion of the 25-part series introduces probabilities calculated from outcomes that are not equally likely. Class members use tables to calculate probabilities of events, add outcome's probabilities, and find...

Don't part with a resource on partitive division. Continuing along the lines of the previous lesson, pupils create stories for division problems, this time for partitive division problems. Trying out different situations and units allows...

Future mathematicians learn how to evaluate numerical expressions by applying the order of operations. They evaluate similar-looking expressions to see how the location of parentheses and exponents affects the value. 

Don't just think outside of the box — read outside of it! The 15th lesson in a 22-part unit provides pupils more work with box plots. Learners read the box plots to estimate the five-number summary and interpret it within the context....

Students explore satellite orbits and gravitational force.

Young scholars explore concepts of probability and independent events. They develop a formula for deviation percentage.

Math whizzes use data from simulations to make theoretical generalizations and discuss possible relationships between several given events. They use a simple card game to generate data to be analyzed.

Students conduct an experiment, determine if a game is fair, and collect data. They interpret data, then display line graph. They conduct analysis of game for probability.

Students engage in a discussion about their preconceived ideas about kindergarten. They share their feelings about being in kindergarten and listen to the book "Oh, The Places You'll Go!" by Dr. Seuss.

Students explore the components of a KWL chart as they examine the facts of a story about the Leaning Tower of Pisa. Vocabulary from additional stories is utilized to form antonyms and synonyms.

Students explore various cultural identities. They conduct Internet research, develop a questionnaire that profiles information from their selected culture, and write a letter to a pen pal in the U.S. explaining what life in their...

Sixth graders study the culture of China by comparing it to that of the United States. They write all questions and notes in a journal. The students access the internet to obtain the information and internet sites are suggested in the...
