Trading Spaces
Let siblings or best friends decorate each others bedrooms. The object of the game is to create a beautiful room for your friend or sibling without them knowing how you are decorating it. Enlist two adults to assist with the renovation efforts and assign a budget and specific rules for each room. Identify items or areas of the rooms that are off limits or cannot be altered such as knocking down walls or cutting a bed in half.
Give the players one day to redo each others' rooms and don't allow peeking while the renovation is in progress. Videotape the big reveal so you capture the child's reaction when he sees his room for the first time.
Green Room Redesign
If your child is ready for a room makeover but you aren't ready to shell out big bucks, play a game that allows her to redecorate using objects around your home. The object of the game is to see how green your child can make her room redesign using items around the house.
Give her a list that details which items in the house are off limits, such as a priceless vase in the living room. Ask her to give you an idea of room décor motif before she goes on her object hunt and determine whether you will allow her to paint her walls or furniture. Count the number of recycled items she adds to her room and don't peek while she is creating her new design. Let her unveil her room to the family and boast about how many found objects are making her room the greenest in the house.
What Looks Different
The object of the game is to see if the kids can identify changes you make to a room. Bring everyone into one room and tell them to take a good look at the items in the room. Lead the group out of the room then make changes. Move items around, take some away or add other items from different places in your house. Don't let the kids see you bringing items in and out of the room. Bring the kids back into the room and ask them to tell you what is different. Do one round where you change nothing and see if the kids notice.
