Number Line helps students visualize number sequences and demonstrate strategies for counting, comparing, adding, subtracting, multiplying, and dividing. Choose number lines labelled with whole numbers, fractions, decimals, or negative numbers. Or use a blank number line, with or without tick marks.

Describe intervals between points on the line using forward or backward jumps above and below the line. Jumps can be labelled with their values or left blank. Add custom tick marks to the number line to show equivalence or compare number values. Show strategies with drawing and annotation tools.

Hide elements of the sequence shown on the number line, which challenges students to use what they know about number relationships and computation to identify those missing elements.

This virtual number line is an open-ended educational tool, ideal for elementary classrooms and other learning environments that use iPads.

• Mark the number line with multiples of whole numbers, fractions, or decimals. In addition, set the starting value of the line, including using negative values.

• Add and manipulate forward and backward jumps, above or below the line.

• Label jump bars, manually or automatically, to show intervals or hide labels altogether.

• Add custom tick marks and values to blank number lines.

• Hide and reveal numbers on the number line.

• Hide and reveal jumps, numbers, and other elements with resizable covers to create your own problems and model strategies.

• Use the drawing tools to annotate work and show understanding.

• Add equations, expressions, and descriptions with the math text and writing tools.

• Share your work by saving an image or providing a share code to others.

Version 4.0.1

New features in Version 4:

• Share your work by saving an image or url, or providing a sharing code to others. Great for creating the initial setup of an activity, then sharing it with students so they can explore it further.

• Enter text directly from your keyboard with the new writing tool. Add labels, descriptions, or instructional text to your work.

• More easily edit equations and other math text using a traditional text field.

• Drawings on the workspace stay visible when the drawing palette is closed.

• Hide and reveal jumps, numbers, and other elements with resizable covers.


Version 4.0.1 includes a number of improvements and bug fixes.

Krrkt pfft ,

Could be even more useful

Pluses:clean design, only app that does this afaik, some customization options.
Minuses: takes some time to get used to using it, scrolling is not super intuitive
Would be even more useful with some additions. 1000 and 10000 steps, zoom in an outis missing. Could be expanded to other units like time, currency, distance etc.
Ideally one could display two lines e.g. Fractions and natural numbers. Thanks for putting this out there.
