Oh No Fractions! offers a simple way for kids to think about and practice fractions. You could use this app in the classroom as another way of demonstrating fractions to students, though having the "Prove it!" feature offered before solving the problem would be more helpful. You can also use it to have kids practice adding, subtracting, multiplying, and/or dividing fractions.

Continue readingOh No Fractions! is an app that lets kids work with fractions in numeric and model form. When they perform an operation, kids use bar models to select the numerator and denominator for the answer. This helps kids find common denominators when needed. When they are finished, kids can choose "I'M SURE" to find out if the answer is correct or "SHOW ME" to see the answer. When kids do comparisons, they must decide if the fraction on the left is GREATER than or LESS than the fraction on the right. Players select an answer and choose "I'M SURE" to check it. They'll see if their answer was "correct" or "wrong" and then be able to "Prove it!" The prove it screen shows each fraction on a bar divided into equal spaces based on the denominator. Kids drag over the boxes to fill in the numerator for each and then see the fractions compared side-by-side on the graph. They can also just tap to reveal the solution. A "STATS" page shows kids their activity and progress and can be easily reset. Kids can set the max denominator up to 99 and can access a simple cheat sheet that lists basic steps for performing operations on fractions.

Continue readingThe concept is pretty simple, but the learning design is elegant, and the visual demonstration of comparing fractions helps kids to really make sense of the comparisons and the operations they perform. It's helpful that kids will see if their answer was correct or wrong and a record of total correct and incorrect answers, but there's no data about which particular fractions may have caused difficulties. Some instructional feedback could boost the learning value of this practice tool.
