Section 1
Find a Fractional Part of a Whole Number
Property
To find a fraction of a whole number, , using a tape diagram, the value is calculated by first finding the value of one unit () and then multiplying by the numerator ().
In this Grade 5 Eureka Math lesson from Chapter 21, students learn to multiply any whole number by a fraction using tape diagrams, building on their understanding of fractions as division. They work through problems such as finding 3/5 of 35 by partitioning a bar model into equal units, determining the value of one unit, and then scaling up to the required number of units. Fluency activities reinforce related skills including reading tape diagrams, finding fractions of whole numbers, and expressing fractions as division sentences.
