Help your child better understand how fractions work with this set of magnetic fraction Segments! Fraction Segments can help teach children fraction concepts such as parts to a whole, equivalents and comparisons. Each fraction is a segment of a circle to visually show how fractions can describe part of a group. Each fraction segment is a different size and is color-coded to represent how different fractions can make up a whole circle. Fraction Segments can be used on any magnetic surface.
