(1) Give each pair 1 board and 2 counters. You might want to use Kinder toys instead of counters.

(2) The goal of the blue frog is to get to the headquarters of the purple frog and vice versa. Students take turns making sentences and jumping.

(3) They can only jump up-/ downwards and left / right (players aren't allowed to move diagonally). If a rock has already been occupied by someone, players have to find another way.

(4) Students can pick bugs on their way to their rival's headquarters. If they jumped on a rock with a bug, they are allowed to make 2 extra steps next time.

(5) The fastest to cross the field wins.
