I created this set of 36 equivalent fractions for my 5th grade intervention group. They have really struggled with the concept of equivalency. Now that we have worked on this for awhile I am using these cards to reinforce equivalency by having them play memory. They have to explain why the two fractions they turned over are equivalent OR why the two fractions are not equivalent. This has really helped cement the concept of equivalency for them. As you know, equivalency is the foundation for all other work with fractions. They absolutely have to know equivalent fractions to be able to move on to adding, subtracting, multiplying, and dividing fractions, as well as simplifying fractions. The picture of the fraction helps them visually see whether the fractions are equivalent or not, but more importantly, helps them explain in words why they are or are not equivalent. These can be used in small groups or as a math center activity. Included in this set is an exit slip (formative assessment) and an answer key.
