A clear, reusable number line for teaching positive and negative numbers

The Teacher's Positive and Negative Number Line is a 70cm x 12cm double-sided teaching resource from Autopress Education, designed to help pupils understand numbers above and below zero. One side shows a horizontal number line and the reverse shows a vertical orientation, giving teachers and parents two ways to present the same idea.

The write-on, wipe-off surface means numbers, jumps and working can be added and rubbed out instantly, which helps children who need to see a calculation more than once before it makes sense. Being able to switch between horizontal and vertical layouts also helps learners who find negative numbers abstract connect "below zero" with a physical position on the line, rather than a rule to memorise.

For schools

• The large 70cm size is easy to use at the front of a class or in a small group intervention.
• The write-on, wipe-off surface supports repeated modelling without needing new print-outs each lesson.
• Two orientations in one resource make it simple to differentiate for pupils working at different stages.
• A low-cost, durable resource that suits whole-class sets, SEND intervention rooms and one-to-one support.

For home learning

• Gives parents and carers a clear, visual way to talk through negative numbers alongside school maths homework.
• The wipe-clean surface means it can be reused for practice without buying replacement worksheets.
• Helps build confidence for children who find abstract number concepts easier to grasp when they can see and point to them.

Number lines are a widely used way of supporting children with additional learning needs who benefit from extra time, repetition and a visual anchor when working with numbers. Being able to physically point along, count and reverse the line gives many learners a more concrete way in than working with numbers on paper alone.

Whether you are setting up a numeracy area in a classroom or supporting maths at home, this number line offers a straightforward, reusable way to make positive and negative numbers easier to picture and talk about.

• Double-sided design: a horizontal number line on one side and a vertical number line on the reverse, so one resource covers two teaching approaches.
• Write-on, wipe-off surface allows numbers and workings to be added and erased repeatedly.
• Teacher's size measures 70cm x 12cm, suited to whole-class and small group teaching.
• Includes one Positive and Negative Number Line.
• Manufactured by Autopress Education (supplier reference NL10).

• Two number lines in one. The reversible design gives a horizontal line on one side and a vertical line on the other, useful for pupils with additional learning needs who benefit from seeing numbers presented more than one way.
• Write-on, wipe-off and built to last. The reusable surface means it can be used every day in the classroom or at home without wearing out or needing replacing.
• Large enough for whole-class teaching. At 70cm long, it is sized for front-of-class demonstration as well as small group and one-to-one intervention work.
• Specialist UK supplier. Supplied by The Dyslexia Shop, a UK retailer focused on resources for learners with additional needs.

Care and Cleaning

Wipe clean with a soft, dry cloth or standard whiteboard cleaner. Avoid abrasive cleaning products, which may damage the write-on surface.

• What is the Teacher's Positive and Negative Number Line?
  It is a 70cm x 12cm double-sided, write-on wipe-off number line from Autopress Education, used to teach numbers above and below zero. One side shows a horizontal line and the other a vertical line.
• How is this number line used in the classroom?
  Teachers use it at the front of the class or in small groups to model positive and negative numbers, writing directly on the surface and wiping it clean between lessons. Its 70cm size makes it easy for a whole class to see.
• Can this number line be used at home to support maths homework?
  Yes. Parents and carers can use it in the same way as teachers do, working through negative number problems together and wiping the surface clean to reuse it for future homework.
• What age or year group is this number line suitable for?
  It is not restricted to one age group, but it is most commonly used from Key Stage 2 (around Year 4) upward, when negative numbers are introduced in the National Curriculum, through to Key Stage 3.
• Is this number line suitable for children with additional learning needs (SEND)?
  Yes, it is well suited to learners with SEND. The reversible, write-on format gives children extra time, repetition and a visual anchor, which many pupils who find abstract number concepts difficult find helpful.
• What is the difference between the horizontal and vertical sides?
  One side presents the number line running left to right, and the reverse presents it running top to bottom. Using both helps pupils see that a number's position, not its direction on the page, is what matters.
• How do I clean the number line?
  Wipe it with a soft, dry cloth or a standard whiteboard cleaner. Abrasive cleaning products should be avoided as they may damage the write-on surface.
• What size is the Teacher's Positive and Negative Number Line?
  It measures 70cm by 12cm, making it the larger of Autopress Education's number line sizes and suitable for whole-class visibility.
