In this polygon activity, students identify similar polygons and corresponding sides. They use a compass and ruler to construct polygons, determine the sum of the angles in a given polygon. There are 4 multi-step problems in this...

In this polygons activity, 10th graders solve 10 different problems that include determining various interior angles in polygons. First, they determine the number of sides a polygon has with a given measure for each angle. Then, students...

Is that a right triangle or a wrong triangle? Young mathematicians look at eleven different shapes and use a measuring tool of their choice to determine which triangles have right angles. Consider cutting out sets of the shapes to...

In this perimeter and area worksheet, students solve 6 word problems where they must determine the perimeter or area of complex figures. Diagrams are provided and real world applications like gardens and carpeting are used in the problems.

Students create books about shapes.  In this shape lesson, students select a topic such as points, lines, angles, planes, polygons, quadrilaterals, triangles, circles, and polyhedra.  In groups, they create an illustrated...

Students examine the correlation between art and math. Using their computers, students construct and measure angles. Students identify the properties of angles and polygons. They engage in the Angles program on their Palm and use the...

In this angle sum learning exercise, learners find missing angles of 20 triangles and quadrilaterals.  Students find the missing angle in each polygon by using the total degrees of each and given angle measures.

In this geometry and measurement worksheet, students solve 20 problems pertaining to parallel lines, geometric figures, right angles and simple measurements.

Circles, circles, everywhere! Pupils learn all about circles, central angles, inscribed angles, circle theorems, arc length, area of sectors, and radian measure using a set of 12 lessons. They then discover volume formulas through...

Colorado would probably object if Wyoming enlarged its borders. Scholars use an interactive map to change the borders of U.S. states to see how angles change. They then answer questions about regular and irregular polygons.

It does not divide into 360 evenly, so it cannot work. The resource extends pupils' thinking about rotational symmetry. By asking for a figure with a rotational symmetry of a seemingly impossible angle, the activity requires learners to...

What do skateboarding and baked goods have in common with math? You can use them to connect half-pipe ramps and cakes to arcs and sectors. Pupils compare the lengths of three different ramp options of a skate park. They calculate the...

It's time to show what you know! Individuals first review finding the area of polygons using the formulas from parallelograms to regular polygons. They then brush up on finding the area and circumference of circles, as well as reviewing...

Not particularly coloful, but definitely informative, here is an introductory presentation on polygons. The basic shapes are covered, from triangles to decagons. Special polygons like the trapezoid and the rhombus are also covered. Not...

Use the alphabet as a tool for teaching your class about geometric figures. Break apart capital letters into line segments and arcs. Classify angles as right, acute, or obtuse. Identify parallel and perpendicular lines. An excellent...
