Explore color through an examination of pointillism and light. Class members view Georges Seraut's famous painting on a computer, zooming in and out to see the details and effects of the technique. They then cover how light and color are...

In this circle worksheet, students use a drawing of a circle. The diameter is given. Students find the radius, circumference and area of the circle. On the second problem, students are shown a circle with a hole inside it. They compute...

Sixth graders discover what circumference is.  For this measurement lesson, 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 calculate the diameter, radius and area of a circle. In this geometry lesson, students investigate the different ratios of a circle. They calculate the surface are of each circle.

Learners construct a cylinder made of paper with detachable bases. Then they are taught the formulas for finding the area of a curved surface and the total surface area of a cylinder. A great hands-on approach!

In this geometry worksheet, students solve the area of 2D shapes starting with squares, rectangles, parallelograms, triangles, rhombi, trapezoids, circles, and ending with area of shaded regions. There are 20 questions.

In this perimeter and area learning exercise, students find the surface area of given polygons.  They determine the area of shaded regions.  This one-page learning exercise contains 10 multiple-choice problems.  Answers...

In this geometry worksheet, students find the area and perimeter of 6 different compound shapes containing squares, rectangles, triangles, and half circles. 

In this area of a circle worksheet, students determine the ratio of common area when two circles overlap and each passes through the center of the other. A detailed sollution is included.

Sixth graders explore characteristics of similar objects. Using attribute blocks, they explore the ratios of the perimeter, area and side length in similar shapes. They calculate and compare the area of shapes.

Even kindergartners can draw triangles in circles, but the assessment task requires a bit more geometric knowledge. Scholars investigate triangles that have a diameter of a circle as one of its sides. They must consider triangles that...

Gobble up a slice of the task. Scholars first consider the area of a whole pizza, half a pizza, and a quarter of a pizza. They then consider other central angles and develop a formula for the area of any sector of a circle.

What properties does area possess? Solidify the area properties that pupils learned in previous years. Groups investigate the five properties using four problems, which then provide the basis for a class discussion.

Do your students have what it takes to be the king of math? Find out with this fun skills practice game that covers a wide range of topics from counting and basic operations to measurement and fractions.

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...

A good mix of Pre-Algebra problems, learners tackle everything from proportions and equations, to polygons and circles. The sections are broken up by topic with a list of the skills that are required to complete the questions. 

This activity is a follow-on activity to inscribing a square in a circle. The overall problem is more complex. It deals with geometric constructions, properties of triangles, and regular hexagons. The final part of the activity...

Inscribing a square in a circle brings up a number of interesting geometry topics including triangle congruence and how to prove a quadrilateral is a square. This activity is followed up by finding the area of the square and determining...

Geometric shapes make great visual models for introducing young mathematicians to the concept of fractions. Looking at a series of four circles, students are asked to determine whether or not one half of each circle is shaded. To support...

Explore lines tangent to a circle. In this math lesson, high schoolers manipulate circles and lines on a TI calculator. They draw a circle  and analyze perpendicular lines intersecting the circle in only one place. This activity...

Help learners understand that perimeter and circumference are one in the same. Learners apply their skills to determine the perimeter/circumference of triangles, rectangles, and circles. They then use the same strategy to find the...

They say real estate is location, it might be more about area. Learners work individually and in groups to design subdivisions by dividing the land up into lots. Scholars design floor plans to fit on the lots along with including a park....

Assess your learners on the five themes of geography and the most important key terms and concepts from an introductory geography unit. Here you'll find an assessment with 15 fill-in-the-blank and 14 multiple-choice questions, sections...

Explore methods for finding the volume of different three-dimensional figures. The 20th lesson in the 25-part series asks learners to interpret diagrams of 3-D figures and use formulas to determine volume. Scholars must use the...
