Instructions

Play through this interactive game to learn about Understand Irrational Numbers. Suitable for Grade 6, Grade 7, Grade 8.

Main Concepts

All numbers (including fractions, percents, square roots) can be expressed as a decimal.

Know that a fraction that is repeating can be converted to a fraction and fraction can be expressed as a repeating decimal.

A rational number is any number that can be represented as a/b where a and b are integers and b≠0.

Decimal expansion repeats eventually.

An irrational number cannot be expressed as a ratio between two numbers and it cannot be written as a simple fraction because there is not a finite number of numbers when written as a decimal. Instead, the numbers in the decimal would go on forever, without repeating.
