Big Ideas: Fractional parts are equal shares or equal sized portions of a whole. Two equivalent fractions are two ways of describing the same amount by using different-sized fractional parts. This lesson builds on students’ understanding of unit and non-unit fractional amounts. The task allows students to investigate equivalent fractions using fractions strips. The lesson sets the student up to discover and understand that different fractional parts can name equal sized portions of a whole. This lesson builds toward students' future work with reasoning about the size of fractions. Vocabulary: equivalent, fraction, numerator, denominator, part, whole Special Materials: fractions strips
