This applet allows students to individually practice working with relationships among fractions and ways of combining fractions. For a two person version of this applet see the Fraction Track E‑Example.
Click on the pile to turn over one card. This is your target fraction. Move the markers so that the sum of your moves is a fraction that is less than or equal to the target fraction.
For example, if the first card turned over is 4/5, you could move the fifths marker to 3/5 and the tenths marker to 2/10, because 3/5 + 2/10 = 3/5 + 1/5 = 4/5. These moves are shown below.
There are many other moves that would also be acceptable, as long as the sum of the moves is less than or equal to 4/5.
When you have finished your move(s), click on the pile to get a new card.
The Sound On button can be used to add some excitement!
