4th Grade • 1 Lesson Plan
$2.00

Lesson Plan Description

Our 4th graders need multiple opportunities to practice using fractions with different strategies so each student can “see” this complex skill in a way that makes sense to them.  They will:

  • Collaborate with peers to practice the “language” of math
    • Construct viable arguments and critique the reasoning of others
  • Practice subtracting fractions using number lines, grids and puzzle models in order to model with mathematics
  • Decompose a fraction into a sum of fractions with the same denominator in more than one way
  • Solve real world tasks involving subtraction of like fractions
  • Rename improper fractions as equivalent mixed numbers
  • Complete an exit slip to help you determine next instructional steps
