Lesson objective: Generate equivalent fractions for whole numbers.

This lesson helps to build procedural skill with generating fractions equivalent to whole numbers. A number line is used in this lesson. Linear models are the best model for highlighting the concept that between any two numbers there are an infinite number of fractions.  Therefore, a linear model gives students a good feel for relative size of the numbers. It is important for the teacher to clearly explain what length is the whole. 

Students engage in Mathematical Practice 4 (model with mathematics) as they represent fractions using an area model, a number line, and numbers to show equivalence. 

Key vocabulary:

  • equivalent
  • number line
  • partition
  • position

Special materials needed:

  • Fraction manipulatives may be needed to support In-Class Practice.
