Number Lines to 20

What is the resource?

This PDF provides blank number lines, labelled from 0 to 20. Designed for young learners building on counting skills and early maths operations.


Why are number lines important?

They offer a visual tool for connecting abstract numbers to actual quantities:

  • Understanding 'bigger/smaller': Seeing '8 is less than 12' on the line gives meaning.
  • Counting on & back: Hops along the line make addition/subtraction less of a mystery.
  • Measuring sense: Rulers work this way – early practice translates to measuring tools easily.
  • Problem-solving basis: Estimation, even graphing, later on, links to this simple principle.


Why is this resource helpful?

This format empowers various maths concepts for younger learners:

  • Supports hands-on activities: Kids use counters, and 'jump' fingers along the line for activities.
  • Visualising addition: Two 'hops' combined into a total – make abstract sums less baffling.
  • Comparing quantities: The visual layout emphasises which number is larger/smaller.
  • Printable PDF: Ensures all students have this basic tool at hand at every lesson.

Number lines provide a bridge between simple counting and deeper number reasoning.  They help kids feel at ease with early calculations.
