Op!

Op! +/- is a fun mobile app designed by a remedial teacher! This app allows children to learn their addition and subtraction tables through play, while introducing concepts such as commutativity (3 + 1 = 1 + 3) and missing terms (12 - ? = 4). A gentle progression of difficulty within each table helps children advance without even realizing it! Op! +/- is especially useful to support school learning, presenting the tables one by one; consistent with classroom teaching.

Description of the educational content of Op!

- Additions by isolated tables from 0 to 10
- Subtractions by isolated tables from 0 to 10
- Commutativity and mathematical reversibility (3 + 1 = 1 + 3)
- Missing terms (12 - __ = 4)

Op! allows both educators and parents to further diversify their teaching approaches to strengthen, in children, the math learning that must become automatic.

Goal of the Op! game

In this game context, the goal of the Op! app is for the child to progress at their own pace, feel valued through their successes in learning and to automate their math calculation skills. With Op! +/- learners are motivated to learn as they are encouraged by positive and immediate feedback after each correct answer!
