Fraction models demonstrating how to decompose 1/4 into unit fractions using horizontal rows.
A math worksheet showing three rectangular models divided into rows to illustrate fractions. Each rectangle is divided into four columns, with shaded portions representing fractions. The first model shows 2 rows with 1/4 shaded, the second shows 2 rows with 1/4 shaded, and the third shows 4 rows with 1/4 shaded.
