Students explore circumference and diameter. In this math lesson, students apply their knowledge of circumference and diameter to solve mathematical riddles. Students apply this knowledge to find circumference and diameter of various...

In this online math worksheet, learners solve word problems the involve circles. This excellent resource allows the students to check their answers, and to get "hints" should they run into difficulties. A terrific teaching tool!

Students construct the formula for the area of a rectangle.

In this skills review worksheet, students answer 10 questions that spiral review volume, unit conversions, perimeter and area of an irregular figure, and sketching views from a base plan.

In this Quadratic Koch activity, students fill out a chart about the edges, edge length, total length, and different areas of a snowflake. Students do this for 8 snowflakes.

Students work with given formulas to solve for specific variables. The calculation of the volume of a cylinder and the change in volume when there is a constant surface area is analyzed in this lesson.

Learners explore the concept of estimating and organizing a group of objects into an array to count the exact number of items. They create their own arrays and practice elements of estimation.

Young scholars measure the perimeter and area of their polygons. In this geometry lesson, students calculate the volume and area using the correct tools. They calculate the time and temperature and the perimeter and side lengths of...

For this geometry worksheet students explore similar polygons and determine measure of missing sides and angles. Students use indirect measurement with similar triangles and determine the area and volume of similar figures. The...

Students perform transformations and translations using polygons. In this geometry instructional activity, students perform transformations on a coordinate plane. They identify the image and pre-image of each figure.

Students learn the difference between perimeter and area by watching a video and a hands on activity.

Eighth graders practice using basic measurements to solve word problems.They also investigate finding the perimeter of different polygons and define the characteristics to classify the shape as a polygon.

Students explore tessellations. In this shapes and geometry lesson, students describe the attributes of many of the shapes displayed on an Elmo. Students create examples of tessellations using pattern blocks.

Pairs of geometry whizzes work together to determine which of three differently shaped cylinders will have the greatest volume. Pupils cut out the three rectangles embedded in the plan, and tape them together to form a cylinder. From...

Middle schoolers redesign their school to make it more energy efficient, and create a model of their design. Learners get together in groups of 5, and they take on the task of making their school more energy efficient. To do this, they...

Students study units of measure like cups, pints, quarts and gallons. They work in groups to create their own mixtures of trail mix using the measuring cups. Then they make a gorilla puzzle using a gallon bottle.

Sixth graders discover what circumference is.  In this measurement lesson plan, 6th graders identify the radius and diameter of different circles. Students discover how to find the area of a circle using the radius and diameter.

Students examine a math worksheet and determine how to divide a single triangle into four of equal area. Using geometric principles, they sketch two additional ways to divide into into four equal triangles. To conclude, students...

Students find the factor of proportionality in similar polygons. In this similarity of polygons lesson plan, students measure the sides and angles of polygons and derive a factor of proportionality between corresponding pairs of sides...

In this solar electricity and satellites worksheet, students calculate the perimeter of a satellite, they find the area of the surface of the satellite and they determine if there is sufficient space for enough solar panels to supply the...

Students calculate the length of the classroom using non-standard units of measurement and estimation. Using a cracker box, they discuss measuring various objects in the room as a class, and independently estimate and measure the length...
