In this Grade 5 Eureka Math lesson from Chapter 17: Making Like Units Numerically, students learn to subtract mixed numbers and fractions greater than or equal to 1 by finding common denominators and converting to like units. Students practice applying this skill through real-world word problems involving distances and time, using number lines and tape diagrams as visual supports. The lesson builds fluency with unlike-unit subtraction and prepares students to solve multi-step problems requiring regrouping with fractions.
Section 1
Subtracting Mixed Numbers on a Number Line
To subtract mixed numbers on a number line, start at the first number (minuend) and move to the left by the value of the second number (subtrahend).
