Making bread with kids is loads of fun and a lot easier than you might think. You can buy your the dough premade and work from there. Goretti's has great dough and are great supporters of the community here in town so I am extra happy to recommend them.
I you are wanting to make bread from scratch, here is the recipe I use with kids:
3 cups flour
1 cup warm water
1 packet of yeast or 2 1/4 teaspoons yeast
1 tsp salt
Mix everything together until flour is all incorporated. Kneed the dough at least 10 times. Let rise in an oiled bowl until doubled. Put the bread in a warm place and cover with plastic wrap or a tea towel. This usually takes about an hour. Punch down and kneed again about 10 times. Put in a loaf pan and let rise again until it is looking like bread. This usually takes less than an hour. Bake at 450' for 30 minutes or until crust is lightly brown. Cool before cutting.
We love making bread in our house and have found a number of great recipes. One of my favorite is from this book. We make bread on a weekly basis.
