Middle schoolers explore lines, rays, line segments, and planes. In this math lesson, students discuss the math concepts and direct their instructor in graphing functions. Middle schoolers collaborate in graphing additional functions.

Here is a study guide on transformations that includes reflections, translations, dilations, and rotations. It also has definitions, helpful diagrams, and several examples involving transformations on the coordinate plane. The lesson...

In this measurement instructional activity, learners examine the Pythagorean Theorem, perimeter, and areas of right triangles. They record their measurements and research their findings on a grid.

With this interactive lesson, learners compute the surface area of rectangular prisms. They visit an online investigation applet and record data on the provided handout. Pair this lesson with the volume lesson by the same publisher as an...

You and your class will like this lesson on using visual models to relate the volume and surface area of solid shapes. Learners construct three-dimensional forms using nets. They calculate the surface area and volume for each and then...

High schoolers identify the volume of cones and pyramids. In this geometry lesson, students derive the formula for cones and pyramids. They calculate the volume of cones and other three dimensional shapes.

Middle and high schoolers calculate the volume of cylinders. For this geometry lesson, learners differentiate between rectangular prisms and cylinders. They use the correct formula to solve for each solid.

Explore the concept of volume of prisms using an applet to perform the calculations. The link to the interactive applet is embedded into the lesson plan as well as a link to associated data sheets. Get your math class to the computer lab...

Introduce the procedure needed to find the volume of a rectangular prism. Learners rank various prisms such as cereal boxes and tissue boxes from smallest to largest volume. They use an applet to find the volume and surface area of each...

Get a handle on equivalent fractions through the use of manipulatives. Using area models, sets, and length manipulatives like fraction strips and Cuisenaire rods, the class will gain a deeper understanding of equivalent fractions....

Students use a dictionary to gather appropriate information for writing simple definitions. They recognize prefixes that relate to numbers, such as mono-, bi-, and tri-. Pupils use their creative abilities to extrapolate new words to...

Pupils make a ladybug art item using math vocabulary and measurements of circles. Ladybugs are made using a compass. Once the bug is complete, attach a previously-written Haiku to it.

Identify the length, width, and height of prisms. Critical thinkers calculate the volume of prisms given small amounts of information. They derive the formula given the length, width and height.

Students describe environmental interrelationships using list of criteria. They are able to explain organism interaction, based on definitions provided. Also, students can use references and worksheets, to describe effects of pollution...

Fourth graders investigate the concept of prime and composite numbers. Students study the visual representation for the numbers and use the pictures in order to develop designs for larger numbers. The goal of the lesson is for them to...

Students explore the concept of Pascal's Triangle. In this Pascal's Triangle lesson, students use an applet called 'Coloring Multiples' to explore Pascal's Triangle. Students develop patterns starting with various numbers in Pascal's...

If both pairs of opposite sides of a quadrilateral are congruent, is the quadrilateral a parallelogram? This task asks learners to determine the answer and to support their answer with a proof. The resource includes a commentary for...

Build a scale model of a home built out of shipping containers. A hands-on activity has scholars watch a video about a home built from shipping containers and then design their own home. They build scale models of their designed homes...

In this transformation of alphabet letters worksheet, students choose whether three alphabet letters have been reflected, rotated or translated.
