Visual Fractions and Equivalent Fractions Worksheets

Use equally divided models to connect a shaded region with its numerator and denominator, then compare equivalent representations.

Where to start

Start by checking that the parts are equal. Ask learners to name all parts and shaded parts separately before matching a fraction to a picture.

A common mistake

The denominator counts all equal parts, not just unshaded parts. A different number of pieces can still represent the same amount.

What to try next

Draw a second model of the same fraction. Move to unlike-denominator arithmetic when equivalence is understood.
