The problem: calculating well and calculating fast are different
Accuracy comes first, and then speed. A student who knows 7 times 8 may still freeze when asked to choose among several operations. A target game trains that choice, because the player must decide which number to use first and which operation gets closer to the goal.
The target can always be reached, so the player knows a solution exists. If the grid is too hard, the player can skip it and see a possible solution.
The rules of the target number game
- Tap a number, an operation and a second number. The result appears, so the player can use it again
- The player uses each number once, but a division must be exact
- Addition or subtraction gives 1 point, multiplication 2, division 3
- The Coup Parfait, using all four operations in one calculation, gives 13 points
- A round has 10 grids, up to 130 points
Four levels set the target range: Facile from 10 to 40, Moyen from 20 to 60, Difficile from 40 to 120 and Expert from 60 to 300.
Four timed challenges
- Sprint: 10 points in 60 seconds
- Marathon: 30 points in 3 minutes
- Défi Parfait: one Coup Parfait in under 2 minutes
- Survie: 45 seconds to start and 10 more seconds for each grid solved
As players climb 6 ranks from Novice to Grand Maître des Chiffres, they collect 12 badges such as Tireur d’élite, Acrobate mental and Démon de vitesse, and track success rate, best streak, best round and fastest time.
A good fit for these readers
Middle school students in Grade 6 (6ème) to Algebra 1 (3ème) can practice multiplication, exact division, orders of magnitude and strategy. Parents can play with them: a round is short and the neon style appeals to teenagers who do not want a childish interface. The app has no advertising and is available in English and French.
A Google account saves progress online. Moreover, an animated tutorial and a worked example explain the rules the first time you open the game.
The game is also a quiet way to build number sense. Estimating whether 6 times 9 is close enough to the target, deciding when a subtraction helps, and spotting that a division can be made exact all matter later in algebra. Because the player sees the result right away and can reuse it, the thinking happens in small steps rather than in one big leap.
Playing your first round
- Install Numéro Cible on your Android phone or tablet.
