Fractions

Nice coverage of the topic. The scoring of the first quiz reported all answers were incorrect. Maybe I was doing something wrong but I am certain that all of my answers were correct. Please check that out. I wouldn't recommend this to my students until that was fixed.

This is a very easy to follow app. We have only gone through the first three chapters so far and my only problem is that the quiz at the end of chapter three shows a box divided into four parts with three squares shaded and the book says that it represents 3/3. Apparently there is at least one more incorrect answer later in the book. Fix those and this is a five star app.

The eBook is well-done, and free to boot. The small tests at the end are good. Page 23's test answer is incorrect. It states that 1/3+2/3=4/6 rather than 5/6.
