Hands-on investigation of Riemann sums becomes possible without intensive arithmetic gymnastics with this interactive lesson plan. Learners manipulate online graphing tools to develop and test theories about right, left, and...

I like algebra, but graphing is where I draw the line! Worksheet includes three multiple-part questions on interpreting and drawing line graphs. It focuses on the abstract where neither axis has numbers written in, though both are...

In this math worksheet, students use protractors to measure each of a set of angles. This is a worksheet generator, the teacher controls the minimum and maximum angles students are presented with as well as whether or not to rotate...

Second graders calculate mileage for a journey. For this place value and measurement lesson, 2nd graders read Johnny Appleseed, work in groups to locate his birthplace on a map, locate the other states he stopped in, and measure the...

Bring out the inner artist with this Abraham Lincoln lesson. Elementary young scholars work on a home project creating a hat similar to Abraham Lincoln's hat. They will use geometry and measurement to create the scale of the hat, then...

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...

If members of your class wonder where they can use the math they learn in middle school, let them discover the answer. Learners apply geometry concepts of scale and measure to calculate the costs of framing a house addition.

Sixth graders observe school ground trees planted nearly 3 decades ago.  For this ecology lesson, 6th graders examine a group of trees planted near their campus and measure the diameter, circumference and growth of the tree compared...

In this triangles learning exercise, 10th graders solve and complete 10 different problems that include applying the Triangle Inequality Theorem. First, they use the illustrated triangles and the data table to test the theorem. Then,...

A series of geometry worksheets have mathematicians constructing, dissecting, overlapping, and measuring as they analyze angles in various contexts. Learners use symmetry and reflections in a compass rose to write instructions on...

An AP calculus lesson begins with an activity to determine the volume of a solid using a cross-section. Next, learners review the ways to find the area between two curves , as well how to find the volume of a solid created...

Follow this engaging slide show on the calculation of polygon perimeter with some hands-on measurement of perimeters to solidify the concepts. On this webpage there are interactive assessment questions and links to related resources by...

Review guide, practice test, homework packet? Yes, yes, and yes as it's all possible with a wonderful trigonometry packet. Every type of problem is there, starting from the unit circle and ending with conic sections. 

In this geometry review instructional activity, 10th graders solve and complete 33 different problems that include identifying various geometric figures and parts of a circle. First, they find the radius of each circle given its...

Students practice calculating probability, see how geometry can help solve probability problems and explore platonic solids.

For this sorting and graphing worksheet, students sort 15 objects and then fill in bar graphs to tell how many of each shape there are. The shapes are: heart, star and triangle.

Students measure prisms and determine their volume. For this measurement and reasoning lesson, students estimate the volume and area of prisms. They measure given boxes. Students use paper to create prisms and cylinders. They determine...

In this isosceles triangle worksheet, students solve 19 multiple choice and short answer problems.  Students use the isosceles triangle theorem to determine unknown angle measures.

Your class will investigate the relationship among different triangles. This geometry lesson, demonstrates how to make a connection between triangles and the Pythagorean Theorem. They identify the missing side or angle of a triangle.

High schoolers differentiate lines and angles using betweenness in this geometry instructional activity. They differentiate angles and lines using Cabri Jr. and analyze the data and make conjecture.

Pupils explore the concept of angles and transversals. They construct parallel and non-parallel lines cut by a transversal using Cabri Jr. Learners then determine which angles are congruent and the relationship of angles when two lines...

Pupils investigate similar triangles and proportions as they make conjectures about the length of sides of similar triangles. For this lesson, have your class construct similar triangles using Cabri Jr so that they share a common vertex.

Fifth graders use the Internet to learn about translations, reflections and rotations. Students access the Transmographer program on the Internet, where they practice what they have learned. Students also complete a worksheet.

Students view a PowerPoint for a warm-up lesson. They practice measuring around the classroom, measuring such things as the length and width of a desk, pencil, door, and book. Students use a website to practice measuring angles.
