Students examine tessellations and their geometric properties. The lesson and discussions may be used to develop students' understanding of polygons and symmetry as well as their ability to analyze patterns.

Students respond to questions based on quotes, research, and logic, and challenge problems related to the current objectives.

Students reflect on the data they have analyzed during the Global Sun Temperature Project. They use the project website as a resource for their observations, draft a class report and post it on the Internet.

Students work together on a word problem. They write a written report of the answer. They participate in a chessgame in which the answers are used.

Students make either and insect or a spider using materials their teacher provides. They then draw of picture of their organism and defend why it is either a spider or an insect.

Fourth graders investigate the patterns associated with both triangular and square numbers. They use counters as manipulatives to depict the numbers as needed but focus on problem solving using mental math techniques.

Students use scientific methods during field and lab investigations. Students collect specimens and make measurements using the metric system. Students describe biotic and abiotic factors in an estuary and design a model.

Students build a working definition of regular fractal, look carefully at the concepts of dimension and scale, and are introduced to logarithms. They solve simple exponential equations for the exponent both by trial and error and using...

Eighth graders find the length of the third side of a right triangle.

Students measure the lengths of provided leafs to the nearest millimeter. Students identify trends in the data as well as sourced of inaccuracy and formulate additional questions that could be investigated to enhance their understanding.

Students solve problems by discovering the eigenvalues that satisfy design questions. They explain how relaxing a small angle approximation can change the solution. Students apply the numerical model of pendulumm motion to solve the...

Sixth graders examine the concept of compounding interest on invested money. They explore how much interest their money would earn through compounded interest. Students conclude that they should invest early and often.

First graders are introduced to how to use a ruler and its purpose. Using a boomerang, they estimate its length and then measure it using a string and ruler. In groups, they practice the same exercise with various objects while...

In this math instructional activity, 6th graders use the time at home in order to work on the skill of recording data in the form of daily activities and statistics.

Students create a timeline on the history of evolution. In this biology lesson, students research their assigned scientist's contribution to evolution theory. They write a three-paragraph analysis about the timeline.

Students create a spreadsheet to chart favorite colors, then collect data, create appropriate charts, and use percentages to describe quantities.

Students use the digital camera, identify geometric shapes (in nature as well as man-made), and gain a better understanding of geometric vocabulary. They search for and recognize geometric shapes in unusual settings

Fourth graders identify major components of a "Cinderella" story in order to create a database.

Students create a classification tree based on grouping candy with eight different properties. This allows students to understand how living things are classified.

Students make simple observations, test mixtures, and make generalized inferences from their observations. They observe bleeding of colored inks with water.

Young scholars make observations about mealworms using hand lenses, rulers, and cotton swabs. Students complete their own mealworm observation chart, then they share their observations with the class. This is one station out of five in...

Students determine a baseline pulse rate then chart the changes in rate with exercise. They describe the changes and develop a rationale for their observations. The task assesses students' abilities to make simple observations, determine...

Seventh graders collect, organize, and analyze data as they research colleges on the Internet. They graph their collected data on a line graph and use a spreadsheet on Microsoft Excel in order to organize the data.

Fourth graders solve problems that can be modeled with algebraic equations or expressions. There are five sets of problems. Students should attempt one problem from each set each day. They increase in difficulty as the week progresses....
