Equivalent Fractions

Our 1/2 fraction flipbook

We begin talking about equivalent fractions after we've had a lengthy discussion regarding the relationship between 1/2, 1/4, 1/8, 1/16. etc. as well as the relationship between 1/3, 1/6, 1/12, etc. The kids have a really good grasp on this idea.

We begin by making our fraction flipbooks (which takes a bit!) and then lifting up a fraction to see its equivalent fractions. For example, when we lift up 1/2, we can see it is equivalent to 2/4, 4/8, and 8/16. After we write down lots of equivalent fractions we find, we discuss their relationship. Finally, we discuss the multiplication and division involved. This is a great visual way for kids to come up with the relationships on their own!
