Fractions

This fractions app was really great! They have different sections that teach and test about different fraction applications. The topics they have are Introductions to Fractions, Equivalent Fractions, Common Denominators, Comparing and Ordering Fractions, Adding and Subtracting Fractions, Multiplying Fractions, and Dividing Fractions. When you choose your topic, you see a window like the one below:

Here you can choose a lesson, questions, using manipulatives, or challenges. I worked through a lot of the different topics. I really liked the manipulative section for each topic. I liked that they were virtually "hands on". When you could visually see what you were doing, it made things very easy to understand.  One of the activities I did is placed below:

This is from the Adding Fractions section. You can change the fractions and as you do, the arrows above also change. By looking at the arrows, it's easy to visualize what it means to add fractions. The third arrow also changes the denominator of the fraction. This helps students see that in order to add fractions you need common denominators.

All of the activities on this app are very helpful. Because there are different topics and different sections for each topic, a lot of time could be spent working with this app. I think this is my favorite app I've found so far and I can see it being a very useful tool in the classroom when teaching fractions.
