Make "inside" and "outside" flashcards by copying several pictures of inside and outside scenes, including indoor and outdoor activities or pictures of items that belong indoors or outdoors -- such as grass and carpet -- onto small cards. Create enough cards to give one set to each child. Use the flashcards as a learning game by having the children sort the cards into an "inside" and an "outside" pile.
To teach preschoolers about day and night, give each pupil a blank piece of drawing or construction paper. Have them draw a line down the middle of the page, drawing a sun on one side of the paper, next to which they print "Day." Next, have them draw a crescent moon on the other side of the page with the word "Night" printed next to the moon. Instruct the children to draw a day and night scene on their paper below the sun and the moon, respectively. Allow the children to explain their pictures. Finish the activity by asking the children to list day activities and night activities.
One activity that is useful for teaching opposites is the "opposite hat." Take a piece of construction paper and cut it into several small squares. On each piece of paper, write a pair of opposites such as "stand up" and "sit down," or "shout" and "whisper." Place the squares of paper into a box or a hat and have each child draw a square from the receptacle. Instruct the children to act out the opposite written on the piece of paper they have drawn.
Teach preschoolers about opposites by having an opposite-themed week. Each day of the week, introduce a new opposite, such as "up and down" or "black and white," along with an activity to go along with the opposite lesson. At the end of the week, allow the children to wear something opposite of what they would normally wear to school, such as pajamas or an inside-out shirt. Wrap up "Opposite Week" with a review of all the opposites the children learned.
