Summer makes me think of camp and camp songs and games.
Remember Going on a Picnic? In that memory game, each player had to say "I'm going on a picnic and I'm bringing ..." and then fill in the name of a food that starts with a letter of the alphabet starting at A and so on. Before giving their answer for the next letter they had to remember all the foods that had already been named.
In my version, I really am going on a picnic! And I want to know what you like to take on a picnic and any tips you have for taking food into the wild. You do not have to begin with the letter A.
