fraction bar.

'The Fraction Bar' provides students with a model for visualising calculations involving finding fractions of numbers.

The tool presents a bar to represent the number, and a line to represent fractions of that number. Students can are guided to locate the solution fraction on the fraction line, and to find the number on the bar that corresponds to it. They can enter other fractions with the same denominator, and their corresponding values in the tool to help them with their calculations.

Feedback is provided to help students locate the fraction, and to find the correct solution.
