Ask the students questions in order to find out whether they know how to play a memory game. Show them an example of a game to give them an idea of the final result. If you prefer, divide the class into teams of two student each. Give a set of 12 card templates (2 x 6 cards) to each student or team. Explain the instructions:
step 1: cut out the cards
step 2: fold on the dotted line and glue
step 3: draw and colour the organisms in the box above their name
