Number line?

One powerful strategy we have used is a fraction number line. I take a long string and tape down the numbers 0, 1, and 2 on notecards evenly spaced. (Make sure you leave plenty of room for fractions in between).
For many days, at the beginning of a math lesson, I have the students sit in a circle on the floor with the number line in the middle.
The first fraction we discuss is where we would place 1/2. It usually lasts at least 10 minutes until they all agree. The tricky part for fourth graders is the fact that 2 is on the number line.
The next day we place 1/4, 2/4, and 3/4. The discussion takes a long time and we dicsuss the word equivalent regarding 2/4 and 1/2. Why are they in the same spot? (2/4 is taped directly below the 1/2)
I then tape the line on the wall.
For the next few days we talk about eighths. There are lots of equivalent fractions that start popping up.
Then, I get into thirds and sixths, etc.
I also have the students make fraction strips themselves, starting with 1 whole, 1/2, fourths, eighth, and sixteenths. We play Marilyn Burns' games Cover Up and Uncover.
