Math Slide: addition & subtraction

Math Slide presents basic addition and subtraction facts, up to 10, in an interactive game format that can be played alone or with up to four players. When playing the game, math problems are presented in various visual formats including blocks, dots, number lines, fingers, and number sentences to increase users’ visualization of numerical concepts and functions.  When playing the game, users are presented a numerical prompt and then they must slide the correct answer from their deck to the middle of the screen. When playing individually, Math Slide keeps time records and users can try to beat their best time. When multiple users are playing together, the first user to match all his or her answers is the winner.

Instructional Ideas

1. Students can use this app to prepare for speed drills and reinforce addition and subtraction skills.
2. Using this app as a model, students can illustrate numbers in various visual forms and create a hands-on paper version of the Speed card game.
3. Teachers can use this game as a formative assessment by playing it with groups of students.
4. Because this app plays so quickly, it can be used during small blocks of time between activities to keep students engaged.
5. Teachers can create a classroom tournament using this app. To do so, teachers can create a tournament bracket and as the games are played, students can advance through the bracket until a champion is crowned. Games can vary from two to four players.
6. A writing component can be added to this app by having students compose brief narratives that explain the procedure they used to deduce the answer. This strategy can be modified by having students first verbally articulate the procedure they used before explaining it in writing.
