Fourth Grade Common Core Math - Explain why a fraction is equivalent to a fraction 4.NF.1
Practice provides two ways for students to practice and show mastery of their ability to explain why a fraction a/b is equivalent to a fraction (n × a)/(n × b) by using visual fraction models.
It includes 40 distinct problems in two sets (129 slides in all!), with and without following answer slides. The PowerPoint file can be used on computers, or Promethean Activboard and Smart boards.

Explain why a fraction a/b is equivalent to a fraction (n × a)/(n × b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions.
