The shape of a molecule is determined by the arrangement of atoms around the central atom and lone pairs of electrons. Scholars build models of molecules using single, double, and triple bonds. They can then see real molecules bond...

Ready to introduce the realities of molecular geometry to chemistry pupils? Use a logic-based interactive! Perfect as individual practice, the puzzles explore the bond angles and repulsions present in three common molecular shapes.

How does the number of sides of a polygon affect the angle measures? Learners recognize a pattern in finding the total measure of interior and exterior angles and the number of diagonals. They use the patterns to calculate...

Get out those protractors! Geometers measure interior and exterior angles of 10 polygons, including a 24-gon. They also calculate the interior angle sum of the polygons. 

Using a word bank, mathematicians fill out a crossword puzzle using 9 clues. Each clue describes a shape, using details such as the number of sides, angle degrees, and the shape category. For example: "A quadrilateral with four equal...

In this angles practice worksheet, students use their problem solving skills to respond to 4 questions that require them to measure angles and turn them.

Learners use a protractor to measure angles. They classify angles by type: right angle, acute angles, and obtuse angles. Students build and draw right, acute, and obtuse angles. They discuss how do people in various professions use...

Learners are given one angle measure, and then determine the corresponding supplementary or complementary angle. A reference web site is given for additional activities. This assignement can be adapted to demonstrate that angle measure...

Here is a complimentary and supplementary angles learning exercise in which learners solve 12 word problems that require them to calculate the measure of angles.

Practice angle estimation with a activity. First learners estimate three angles within 15 degrees, then they measure and name each angle. A reference website is given for additional activities.

In this math learning exercise, learners are asked to used a compass and straight edge to construct copies of shapes, angles and line segments.

Third graders research the Internet to locate geometric designs in familiar buildings. They review shapes, solids, angles and symmetry as they research websites of familiar buildings in Louisville. They record the information they see...

In this sums of angles in polygons learning exercise, 5th graders find the value of x which is the angle that is not given in a polygon. Students complete 4 problems.

Don't be obtuse, this geometry unit is the just the right resource for educating the acute young minds in your class. From classifying and measuring angles, to determining the congruence of shapes, this...

Learners identify various angles and how to measure each type. They use a protractor to measure each of the angles. Students also write the name of the angle and identify the number of degrees for each.

Fourth graders use dancing methodology in a polygon and shape activity. In this shape and dance lesson, 4th graders discuss shapes in dance, math, and everyday life. Students use dancing activities to recognize and analyze shapes.

Although there isn't anything for kids to complete in this shapes handout, they can use it as a guide for drawing shapes and recognizing their attributes. There are eight shapes described here: circle, oval, triangle, rectangle,...

What are these shapes? Here are four shapes with some common attributes: they each have four parallel sides and four vertices. Scholars identify a rectangle, rhombus, square, and quadrilateral. Because there is an explanation written...

Triangles, circles, and rectangles are featured in a colorful, one-page worksheet that defines and illustrates these shapes. Read the explanations with your first graders and have them count the number of shapes in a given box. Since the...

In this shapes activity, students read 5 descriptions of geometric shapes. Students determine what shapes the clues refer to and complete the crossword puzzle.

Third graders create angle eaters where they use circles with cut outs to identify right, obtuse, and acute angles. Students complete 1 angle eater.

Upper graders examine all angles. In this angle lesson, pupils practice measuring, drawing, and naming angles. They create posters regarding angle vocabulary.

Help your students explore shapes. They classify shapes and identify them in their everyday world. Plane shapes are explored, and they classify and identify the plane shapes.

Shapes are all around us! Kindergartenrs identify shapes in their world and guess the shape being described. They participate in a shape hunt.
