Sequence Chart Template – Eighteen Squares

18-Step Sequence Chart – Free Printable Graphic Organizer

This free printable 18-step sequence chart gives students a structured way to organize longer sequences, processes, timelines, or multi-step ideas.

The template includes eighteen separate squares, making it especially useful when a topic contains more stages or events than a simple four- or eight-part organizer can hold.

Students can use each square for a number, keyword, short sentence, symbol, or small drawing.

Classroom Ideas

Use this printable sequence organizer to help students:

• Sequence important events from a longer story
• Build a detailed historical timeline
• Organize stages in a scientific process
• Record steps in an experiment or investigation
• Break a complex procedure into smaller parts
• Plan the stages of a long-term project
• Organize research findings in sequence
• Map the development of an idea or event over time
• Create a visual summary of a chapter, lesson, or documentary

Suggested Grade Levels

This graphic organizer is especially suitable for Grades 3-6.

Because it includes eighteen sections, it works best for students who are already comfortable identifying and organizing information independently.

Teachers can simplify the activity by numbering the squares, adding short prompts, or asking students to complete only selected sections.

Why Use an 18-Step Sequence Organizer?

Some topics cannot be represented clearly in only four or five boxes.

An eighteen-part organizer gives students room to break a longer process or narrative into smaller, manageable pieces while keeping the full sequence visible on one page.

This can help students see:

• What happened first, next, and later
• How one stage leads to another
• Which events are most important
• Where a process begins and ends
• How information changes or develops over time

The structure is particularly useful for extended sequencing and timeline activities.

Ideas Across Subjects
