Supply the children with several clear cups of water. Using food coloring (red yellow and blue) drop colors one drop at a time into the water cups. Have them discover what color they get with blue and red, yellow and red then try blue and yellow. Supply the children with plastic eyedroppers and let them mix the colors in the empty cup. (Add more coloring as desired)
Collect pairs of clean socks in a variety of colors, patterns and size. Place one half of each pair in a laundry basket. Give each child one of the other socks. Hold up one of the socks from the laundry basket. Challenge the children to determine who has the matching sock to make a pair.
Extension: Shoes, too, can be used to play matching games.
Let the children choose a color for your picnic. Then try to incorporate that color into your picnic plans as much as possible. For example, if they choose green, you might wear green clothes, sit on the green grass, use a green tablecloth, eat green grapes, and celery with cream cheese mixed with green food coloring, play with a green ball, or take a walk and look for green things.
