Open Number Line

Open Number Line

The Open Number Line Floor Mat is a long, single-column mat with 20 hash marks equidistant apart
so that they can be used in many different ways to show number sequences. To maximize its flexibility,
it does not come with any numbers written on it.


To create numbers for the number line, you can use large index cards, 5×5 squares of felt, or large
squares of craft foam. Numbers can be written with a thick Sharpie marker. Differently colored cards,
felt, or foam can be used to identify multiples of five, ten, one hundred, or one thousand.


Each activity lends itself to students jumping from number to number and saying the number (or
number value), and/or solving an equation.
