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

Students observe how certain geometric shapes can be used to make some structures rigid and others flexible. The activity involves construction of a 30-60 right triangle, folding while following directions, and identifying polygons.

Students explore the concepts of length, perimeter, and area. In this math lesson plan, students use Shape Explorer to practice finding length, perimeter, and area.

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...

Students walk around the neighborhood and identify various polygons and lines in buildings, nature and other objects. They design a building using various geometric patterns, shapes and lines. Students complete a descriptive writing of...

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...

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...

Fourth graders use polygons to create animal figures with symmetry. In this polygons and symmetry lesson plan, 4th graders create a symmetrical animal collage by cutting and gluing geometric shapes and figures from math...

Geometers calculate the area of plane surfaces using the formulas for the area of a square, rectangle, and triangle. They develop the formula for calculating the total surface area of two geometric solids: the cube and rectangular prism.

Given a very realistic challenge, your young geometers design residential fish tanks in rectangular and triangular prism shapes. They compute the volume of water each will hold. They also determine the size of plastic covers for each...

Learners find the volume of four figures drawn in shaded cube form. A reference web site is given for additional activities.

In this math worksheet, students read an informative chart about how to find the area of quadrilaterals. Students then answer 6 questions in which the area of quadrilaterals is calculated.

Students explore geometry by participating in a school measuring activity. In this perimeter lesson, students discuss the techniques and methods used in order to measure a large perimeter or geometric figure. Students utilize grid paper,...

Students create posters about geometric shapes in order to demonstrate their understanding of the different shapes. Students look for pictures in magazines to represent two-dimensional shapes, paste them on a poster, label the shape,...

First graders identify various shapes in everyday objects. in pairs, 1st graders go on a shape field trip to locate various objects of different shapes. They photograph the objects and later use the prints to write sentences describing...

Students explore kitchen math and following multi-step directions by making pancakes. They assemble the ingredients and make the batter. Students create faces, geometric figures, shapes or lines using pancake batter.
