New iPad® App Helps Build Computational Fluency

Curriculum Associates announces another addition to the i-Ready® Diagnostic & Instruction product line, winner of the 2013 CODiE Award for Best Student Assessment Solution, with the release of the second in a new series of educational games for the iPad®.

During the game, students use number facts, order of operation, and number relationships to create expressions equivalent to 24. Students additionally learn strategies such as making tens, recognizing factors of 24, understanding relationships between operations, and more. At the end of every level, students are also presented with a challenge set that requires them to find as many expressions as possible that are equivalent to 24, given a particular number set.

The app can be downloaded at or by searching for “Door 24” in the App Store.
