KS3 and KS4 Stacked Number Lines Worksheets
Stacked (or double) number lines are used to visually represent relationships between two different sets of values. They are particularly useful in helping children understand the concept of proportional relationships, equivalent fractions, and ratio by allowing them to see the connections between two number lines side by side. They offer a clear way for students to link numbers, enhancing their problem-solving skills and visualising multiplicative relationships.
In the Cazoom collection, you will find stacked number lines being used to: explore direct proportion and when introducing compound measures. New worksheets are added regularly, ensuring there’s always something fresh to deepen your students’ understanding and keep them engaged.

By aligning two number lines side by side, students can clearly see connections and enhance their problem-solving skills. These easy-to-download PDF worksheets are designed to help learners visualise and understand multiplicative relationships effectively. Answers are included to support independent learning, enabling students to build confidence and deepen their understanding.
What are stacked number lines?
Stacked (or double) number lines are visual tools used to display two sets of values in a proportional relationship. They consist of two number lines placed parallel to one another, allowing learners to explore the connections between corresponding values. For example, a stacked number line can show how two values increase proportionally, such as miles and kilometres or hours worked and wages earned. This clarity supports understanding of key concepts like direct proportion and equivalent ratios.
Importance of stacked number lines
Stacked number lines play a crucial role in helping learners:
- Understand proportional relationships by visualising how values increase or decrease together.
- Explore concepts like equivalent fractions, ratios, and compound measures.
- Develop problem-solving skills by identifying patterns and making predictions.
- Build confidence in working with real-world scenarios, such as unit conversions and scaling recipes.
For example, a stacked number line showing miles and kilometres helps learners understand how the two units relate, enhancing their ability to solve conversion problems quickly.
Applications of stacked number lines in Real Life
Stacked number lines go beyond theoretical maths concepts—they have real-world applications:
- Unit Conversions: Help students convert between different measurement systems, like miles to kilometres or pounds to kilograms.
- Ratio and Proportion: Explore practical uses, such as scaling quantities in recipes or comparing costs.
- Compound Measures: Introduce concepts like speed, density, and other ratios involving compound units.
- Budgeting and Planning: Use stacked number lines to compare expenses or plan allocations.
