Students review basic shapes, such as circles, squares, triangles, and rectangles, find objects in those shapes in classroom, watch Clifford's Fun with Shapes video, practice reproducing four shapes, and rotate through four classroom...

Young scholars determine the length and width of leaf samples to the nearest millimeter and the circumference of trees. They participate in a discussion about the importance of collecting specimens carefully. They compile accurate...

Students examine how the circumference, diameter, and the relationship of Pi of a circle are related. They count the summer rings of a tree to determine its growth.

In this geometry instructional activity, students identify radii, diameters, chords, tangents, secants and other terminology associated with circles.  The one page instructional activity contains eighteen problems.  Answers are...

For this Geometry worksheet, 10th graders solve a problems involving area of a circle given information regarding surface area.  The one page worksheet contains one problem with answer. 

In this Care Homework worksheet, students solve a variety of multiple digit addition, subtraction, multiplication, and division problems that include fractions, decimals, and percentages. They demonstrate knowledge of geometric formulas...

In this circles worksheet, students view a set of different sized circles. Worksheet is for reference and has no associated activities.

In this circle worksheet, students study that two semi circles make a complete circle. Students cut out the two halves of the circle and paste them together on the big circle that is shown.

In this distance worksheet, students calculate the angular size or angular diameter of objects at a given distance. This worksheet has 6 problems to solve.

In this heat transfer activity, students observe photographs of the various ways heat is transferred. Included is a radiator giving off heat that rises and cools as it settles, the sun radiating heat to the earth and a house absorbing heat.

For this circle worksheet, students solve 8 problems: finding percentage increase, finding differences in area and perimeter, finding circumference and area.

In this shape worksheet, students focus on the shape of a circle. Students study 8 pictures and put an x on those that have the circle shape.

In this basketball court measurements activity, students complete16 various types of problems using the illustrated basketball court at the bottom of the sheet. They find the diameter and radius of the smaller jump circle on the court....

In this mathematics worksheet, students identify various shapes. Then they circle the correct number of shapes illustrated in each box. There are 10 problems to solve on the sheet.

In this mathematics worksheet, students identify various types of shapes shown. Then they circle the group with the most shapes. There are 8 problems to solve on the sheet.

In this mathematics instructional activity, students solve a number of problems by counting each shape and graphing the amount to the right in height. Then they circle the shape that appears the most often on the sheet.

In this mathematics worksheet, students circle the shape in each group that is different. there are six different groups to identify on the sheet.

Students identify and use descriptive writing and measurement terms to describe a student-created robot. Then they construct robots of materials available and then use AlphaSmarts or Danas to describe the robot using only the dimensions....

Eighth graders measure the circumference and the diameter of circular objects and record the measured values of the circumference and the diameter in a table. They then record their measurements in centimeters and use their data to...

Students use this lesson to determine how circles are different from other shapes. In groups, they determine the accuracy of three theorems based on the uniqueness of circles. They use a software program to hypothesize about the...

Students examine the connection between bones of the human body and math. In groups, they locate bones and determine which instruments are used for measuring. Students organize their findings and create spreadsheets for calculating and...

Second graders explore shapes and create a Silly Shape book. Students recognize that shapes have certain properties and be able to define them. Example, a triangle is any three-sided shape. Students' job is to make a picture on...

Students compare and contrast the orbits of Earth and Mars, locate the planet Mars, and diagram its retrograde motion.

This a straightforward, but interesting, project in geometry. It is a good first proof to try on your own. You should be able to figure it out by yourself, and you'll gain insight into a basic property of circles.
