Adding Fractions with Unlike Denominators

4th Grade • 1 Lesson Plan

Lesson Plan Description

4th graders need multiple opportunities to engage with the concept of adding fractions.  Use this lesson as a formative assessment to gauge where to begin your instruction or as a review of the concept.  Your students will:

  • Collaborate and use the “language” of math
  • Model with mathematics and attend to precision
  • Express a fraction with denominator 10 as an equivalent fraction with denominator 100
    • Use this technique to add two fractions with respective denominators 10 and 100.
  • Complete an exit slip to help you determine next instructional steps
