Playground is a combination sign, combining the signs for play and area.
First sign play, making your hands into fists with thumbs and pinkies extended. Then twist your hands back and forth. Then sign area, taking your dominant hand flat and palm down, making horizontal circles in the air.
Make the playground sign before you head out to the playground, and again once you get there. Your baby will start to make the connection and anticipate visits, even telling you when she is ready to go again.
Use the flash cards and sign as part of your preparation for a visit to the playground. Using the word, flashcard, and sign will help your baby anticipate the visit and will make the meaning of the word more clear.
