Today I'll start with tag "b", kids' activities. It sort of overlaps a bit with tag "c", volunteering with kids sometimes, but not today. How about a simple recipe? This one is for after Halloween: Pumpkin Soup.
One child with the help of one adult can do most of the preparation, but if there are 2 or 3 children, the tasks can be divided among them.
Take a pumpkin that had the face painted on, not carved--or the contents of a jack-o-lantern that was scooped out before the candle went in. Either way, you need fresh pumpkin flesh. The adult gets it started: Cook the pumpkin. If it's still in its shell, an adult can cut off the top and scoop out all the seeds, and bake it in the oven at 375 degrees (fahrenheit) for between 30 to 45 minutes depending on the size of the pumpkin. The child (or Kid #1) can plop the pulp into a big pot, about 2 cups of pulp. Then, Kid #2 should add 3 cups of milk, about a quarter teaspoonful each of ginger and cinnamon, 3 tablespoons of brown sugar (or 2 tablespoons of white sugar), and 2 tablespoons of butter. Kid #3 uses a potato masher to mush it all together. The adult has to supervise the cooking of the soup, because it should just be brought to the boil and not actually boil. Kids can take turns stirring, though. Big kids, with adult supervision, can pull out stray seeds or stringy pulp using a big spoon. You can serve it right away, or put it in the fridge and heat it in the microwave later. It'll smell like pumpkin pie, and taste a bit like it too. (If you don't have fresh pumpkin, you can use canned pumpkin without having to do any cooking before you heat up the soup.)
