1) I grow and change every year, but I always have the same date. I often mean cake and balloons. What am I?
2) I am full of bright slides, tall swings, and a big sandpit. I am where you go to run and shout with your friends. What am I?
3) I come in many colors and fly high when you hold a string. If you let go, I might float away into the sky. What am I?
4) I am the opposite of a grown-up. I love to ask "Why?" and my main job is to play. What am I?
5) I sparkle when you feel happy or when you achieve something great. I am the sign that you are having a wonderful time. What am I?
