Locate the Aliens Angles and Coordinates

This is a game about coordinates and angles. When the game starts the pupil faces an attack from Alien spaceships and has to turn his spaceship some degrees in order to target an enemy spaceship. So first the pupil chooses a number to target an enemy spaceship. After that it has to estimate the turning angle to turn his spaceship in the direction of enemy spaceships. If the pupil finds the right angle, then it has to find the accurate location for every enemy spaceship, so the pupil has to find coordinates x and y. If everything is right, he takes 3 points, one point for every right answer and the enemy spaceship will be destroyed, otherwise pupil has to repeat the try. In every game he has to destroy 6 enemy spaceships but enemy spaceships move every 30 Sec and after they shoot. So if pupils' spaceship is hitted by enemy spaceship, he loses and his spaceship is destroyed. At the end of the game, the game assistant announces to the pupil his grade. This is a fun educational game appropriate for primary school and helpful for Parents, Teachers and children.
