Number Line, by the Math Learning Center


Number Line helps students visualize number sequences and model strategies for addition, subtraction, multiplication, and division. It can be used to represent sequences of numbers, including whole numbers and multiples of a variety of numbers.

Students can use what they know about number relationships and computation to identify missing elements of sequences shown on the number line.

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

For more Number Line resources and other apps, visit:


• Mark the number line with multiples of any whole number from 1 to 100.

• Add and manipulate forward and backward jumps.

• Hide and reveal numbers on the number line.

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

• Write equations and expressions with the text tool.
