Grade 5 students learn to solve and create word problems involving addition, subtraction, and multiplication of fractions, using tape diagrams and expressions to model each situation. This lesson is part of Eureka Math's Chapter 22 on Fraction Expressions and Word Problems and builds on prior skills such as multiplying whole numbers by fractions and converting units of measure. Students also practice writing and interpreting fraction expressions that match visual diagrams.
Section 1
Applying Multiple Strategies to Fraction Word Problems
To solve a multi-step problem, break it down into a sequence of simpler calculations. Different valid strategies, such as calculating parts separately or working with the remaining whole after each step, can be used to arrive at the same correct answer.
Section 2
Modeling Fraction Word Problems with Tape Diagrams
A tape diagram (or bar model) is a visual tool used to solve fraction word problems. A rectangle represents the 'whole' quantity, and it is partitioned into equal units based on the denominator of the fraction. By determining the value of one unit, we can find the value of any number of fractional parts.
Section 3
Creating Word Problems from Tape Diagrams
To create a word problem from a tape diagram, identify the key components: the total value (the whole), the number of equal units it is divided into (the denominator), the number of units being considered (the numerator), and the unknown value the diagram is asking to find. Weave these components into a real-world story with a question.
