Fun Kid Activity: Lines of Colored Tape, straws and pompoms. Try straws and cotton balls. Adding the lines ups the challenge. Using pompoms allows you to adjust the size from tiny to pretty big. The pompoms are also nicer looking.
DIY Outdoor Scrabble or Bananagrams tiles. Take thin board, paint pens, or stencils and spray paint (with an adult's help) and turn a word game into an outdoor fun game! - This would be great for a literacy activities day.
