Students differentiate between ellipse and hyperbola. In this algebra instructional activity, students graph and solve elliptical equations. They use the cabri program to create the different conics and move them around.

Sixth graders explore characteristics of two and three-dimensional figures. They observe the teacher demonstrate the faces, edges, vertices and names of specific figures. In groups, 6th graders examine and describe given figures. ...

Fourth graders are introduced to the vocabulary needed to identify the attributes of two and three-dimensional figures. They work together to create a word wall, which contains the geometric terminology being learned.

Students review the procedure for determining appropriate types of measurements for given situations and measurement conversions. They figure perimeter, area, and volume of 2 and 3 dimensional objects.

In this prisms worksheet, high schoolers answer 10 multiple choice problems about prisms.  Students determine the number of faces a prism has, characteristics of figures, etc.

In this geometry learning tool worksheet, students cut the shape out along the dotted lines before folding and gluing it to form a three-dimensional figure.

Middle schoolers work in small groups to make various geometric solids with Play-Doh. They use fishing line to make cuts and observe the shapes of the cross-sections. Pupils complete an assessment in which they answer questions such as:...

In this AC phase worksheet, students answer 24 questions about AC and DC voltages, phasor diagrams, sine wave graphs and Lissajous figures.
