Fraction Skittles: Introduction to Fractions

Fraction skittles provide a three-dimensional, concrete introduction to fractions. Children see and handle parts of wholes before encountering notation.

Objectives

Materials

Instructions

1. Present whole skittle: 'This is one whole.' 2. Present skittle divided in half: 'This is cut into two equal parts—halves.' 3. Remove one half: 'This is one-half.' 4. Present thirds: 'Three equal parts—thirds.' 5. Compare sizes: which is bigger, 1/2 or 1/3? 6. Name each fraction. 7. Match to written notation.

Educator tip

Always start from the whole before discussing parts. The comparison of fraction sizes is counterintuitive—more parts means smaller pieces.

Assessment

Child names fractions, demonstrates with skittles, and compares sizes.
