### Purpose

• Understanding the structure and coherence of fractions and being able to calculate and use them in practical situations

Visualise the division of a a strip. You can choose to display the fractions in 3 different ways: horizontally, vertically and in a square. Additionally, you can indicate which fractions are visible in the tool.

Press the cursor button in the toolbar to control the tool. Slide one entire plane or fraction to one of the a strips with dotted lines. Drag an entire strip or a fraction to one of the strips with a dotted line. Once the fraction is placed in the field, you can select it and move it to another field. If you select 'align' or 'move freely', you can also place fraction on top of each other. The fraction will disappear if you drop the fraction outside of the strips with dotted line.

Click on 'Reset' to clear all the squares with dotted lines.
