Students conduct an experiment.  In this geometry lesson, students practice identifying, describing and comparing geometric solids.

In this triangle fundamentals worksheet, students identify possible side lengths of triangles. The first three problems give measurements of the sides, students select the combination that is possible in a triangle. The final three...

Students compare and contrast side-scan sonar to other methods used to find objects underwater. In this underwater search lesson, students describe side-scan sonar and make inferences about the topography of an unknown landscape. This...

In this triangle activity, students solve 1 word problem about the lengths of a triangle. Students determine the length of the longest side given the ratio of the angle measures.

In this postulates and theorems activity, learners explore a concept map containing information about angles and sides, alternate interior angles, and diagonals of a parallelogram.  They use the concept map to prove theorems dealing...

In this similar figures worksheet, students identify the meaning of similar, corresponding sides, and congruent.  They use proportions to find the length of a missing side.  Students dilate given figures according to a scale...

Students investigate the relationship between angles and their sides. In this geometry instructional activity, students prove why SSA does not work as a true angle side relationship theorem.

In this geometric figures worksheet, 10th graders solve and complete 18 different types of problems that include various figures. First, they find the area of the figures shown if consecutive sides are perpendicular. Then, students find...

In this area and perimeter worksheet, 10th graders solve and complete 18 various types of geometry problems. First, they find the area of a figure shown with consecutive sides perpendicular. Then, students find the area and perimeter of...

In this find the area worksheet, 10th graders solve and complete 18 different types of problems. First, they find the area of a figure with consecutive sides. Then, students find the area and perimeter of a square shown. They also find...

Students identify and comprehend the concept of limit in mathematics. They also view artistic works illustrating limits by M. C. Escher and apply techniques of one-sided limits to graphs of relations. Finally, students compute limits...

Learners study different pain medications and their side effects.  In this drug usage instructional activity students read articles and complete a worksheet. 

Students solve equations with variable on both sides of the equal sign. In this algebra activity, students combine like terms using opposite signs. They solve for the desired variable using addition, multiplication, division and...

Students evaluate their reaction to a series of statements to investigate that personal choices are based on personal goals, peer and social pressures, ethic and religious beliefs, and the knowledge of biological consequences. This is...

Students examine global issues from different perspectives. In this communication skills lesson, students participate in a classroom activity that requires them to take stances on issues and then consider the support of other...

Role play community members who are both for and against the construction of a dam. Research the pros and cons and then hold a classroom debate. This activity ideally follows a series of stream studies, links to which are included. Use...

In this mathematics worksheet, students give the area and perimeter of each polygon illustrated on the sheet. There are six different polygons to measure on the sheet.

Each slide displays a block and the forces acting on it. Physics pupils consider the angles and figure the one marked in red without using a calculator. This would be a great way to activate learners' brains and practice mental math. Use...

Use a roll of the dice to motivate your kids, or to help them learn to count to six. Six squares represent the sides of dice, ready for your class to use in a game or a math lesson.

More than just a worksheet, the resource provides a thorough guide to navigate through the land of parallelograms. Filled with definitions and theorems, the resource supports learners through problems such as proofs and finding missing...

Imagine using a six-sided cube to encourage readers to analyze a topic in greater depth. Create a cube, label each of the six sides with one of Bloom's comprehension levels, and you're ready to launch a discussion of a text....

A quadrilateral is drawn on the coordinate plane, and eighth grade geometers find the length of each side and the diagonals by applying the Pythagorean theorem. 

Toss 100 pennies (or poker chips or any other two-different-sided objects) and remove all of those displaying tails. Line them up and repeat. The lines of pennies collected get smaller each time, successfully representing half-life.

Excellent lesson! Anne Linehane's geometry story, The Greedy Triangle, offers an opportunity to practice forming various types of polygons with your learners. Using elastic bands (or Chinese jump ropes),...
