Equivalent fractions can be tricky. So my class made this flip book visual to use as a reference.
For the flip book I just had the students use 5 sheets of ditto paper approximately 1 inch apart. Then they fold down the top and staple it. Here's a handy link showing how to make the foldable. Once the foldable is made I use this fraction bar printable that students glue on each step of the flip book. Then they cut the fractional lines on each step to make it manipulative.
