Toys and cars from around the house, roll of masking tape
On a carpeted area or rug, tape down long (5 or 6 feet) strips of masking tape in straight and curved patterns. Make the strips intersect each other to form a system of 'roads' on the floor. Gather toys and divide them up by themes, i.e. railroad, farm, school, construction, etc. Place each group of toys at the end of a road, creating a little city. Drive various cars and trucks up and down the roads and make up stories for your child as to where the cars are going and what they are doing.
