A good activity for young kids.

Get some pieces of A3 paper and draw a large circle on each one.

Pin the circles on different walls in the classroom.

Model the activity: Say "Blue" take a blue crayon, walk over to one circle and color a small part of the circle.

Do this for each color you plan to teach.

Then, say a color ("Blue") to a Student and s/he should pick up the blue crayon and go over to the circle you colored in blue. Let him/her color it a little and then call him/her back.

Continue with other Students.

Colors in the Air:

This is good for very young ones.

Give each Student 2 pieces of different colored paper (origami paper is ideal for this).

Teacher calls a color (e.g."Blue") and the Students with that color hold it up.
