This is designed to help students begin to understand word groupings. I use this in EFL classes in Japan but may help others.
1. Have all students stand in one line.
2. Designate the right side animals and the left side colors.
3. The teacher stands in front and says one word. The students and teacher then jump to the appropriate side and then jump back (jumping back helps to decrease the embarassment of being wrong.)
4. Once students get the hang of it, the teacher can then try to trick the students by jumping to the wrong side.
This can be played as a knock out games or award students who weren't fooled (this keeps everyone in the game and playing.)
Later the sides of the lines can be changed according to what you wish to practice.
