Activities to Teach Students to Identify Parallel, Intersecting, and Skew Lines and Planes

Identifying parallel, intersecting, and skew lines and planes is an essential concept in geometry. As a teacher, it is important to provide students with a variety of activities that can help them understand these concepts. These activities will not only enhance their ability to identify these lines and planes but also improve their spatial reasoning and math skills.

Here are some effective activities that can be used to teach students to identify parallel, intersecting, and skew lines and planes.

1. Paper-and-Pencil Activity – Draw and Identify

One of the simplest ways to teach students about parallel, intersecting, and skew lines is through drawing. Provide students with a set of rulers, and ask them to draw lines on a sheet of paper. Next, they must identify the type of line they have drawn – whether it is parallel, intersecting, or skew.

To make this activity more challenging, you can ask students to draw plane shapes and then draw lines through them.

2. Interactive Whiteboard Activities – Digital Manipulatives

Interactive whiteboards have become an integral part of the classroom. With digital manipulatives, it is possible to create engaging activities that help students understand the concept of parallel, intersecting, and skew lines and planes.

Using digital manipulatives, students can drag and drop lines and planes to understand their relationships. They can also test different angles and positions to figure out which lines are parallel, intersecting or skew.

3. Real-life Examples – Surveyors, Architects, Engineers

Real-life examples can help students connect what they learn in school with the outside world. You can invite professionals, such as surveyors, architects, and engineers, to speak to your class about their work and how they use parallel, intersecting, and skew lines and planes in their job.

You can also take your class on a field trip to a construction site or a map-reading activity where students must identify parallel, intersecting, and skew lines on a map.

4. Group Projects – Tangram Challenge

Group projects can be a fun and creative way to engage students with the concept of parallel, intersecting, and skew lines and planes. One such group project could be the Tangram Challenge.

Provide each group with a set of tangram shapes and ask them to create different shapes by aligning the pieces in the correct position. This activity will require students to use their spatial reasoning and geometric skills.

5. Competition – Angle Challenge

A competition can be an effective way to motivate students to learn. Consider organizing an angle challenge where students must identify angles as parallel or intersecting. You can include different types of angles, such as right angles, obtuse angles, or acute angles.

The competition can be carried out in a quiz-style format, with questions displayed on a screen or as a board game.


These activities are creative, engaging, and effective in teaching students how to identify parallel, intersecting, and skew lines and planes. Through a combination of paper-and-pencil activities, interactive whiteboard activities, real-life examples, group projects, and competitions, teachers can make the learning process more enjoyable and memorable for students.
