Interactive Tool for Visualising Rational and Irrational Numbers 2021 JavaScript HTML5 Applet

Initial state of the interactive

The link to the interactive can be found here.


This is a simple interactive to help students visualise rational and irrational numbers when placed on a number line. For rational numbers, they can manipulate the numerator and denominator to form the desired fraction. They can also change the number of decimal places displayed to gain a better understanding of repeating decimal values. 
Interactive displaying rational numbers 

For irrational numbers, users are allowed to input basic mathematical expressions using common symbols such as + (plus), - (minus), * (times), / (divide) and ^ (power). Moreover, students can input common irrational numbers such as e and pi to facilitate their learning. 
Interactive displaying irrational values

This interactive also comes with a simple number game. Students can generate a random number, after which they can drag the red indicator on the number line to locate the value. A "Check answer" button is provided to help students determine how close their answer is to the desired value.
