Lunch, Snack, and Fun Activities for a Group of 6 Kids

The parent(s), usually bring their child's foods and snacks.
Unless you are being subsidized and in a formal daycare business and have a license and can then attribute costs to your child care business.
You can inform the parents, that they are to bring their child's food/snacks. Also because, all parents have different ideas... about what they want their kid fed with and what "nutrition" is.
And beware of any allergies.

How many hours, are you watching these kids?

Get them outside in your yard. Unless you don't have one.
Do crafts. Therefore you have to buy a good amount of craft items/glue/glitter/hot glue gun/glue/scissors/etc.
Paint rocks.
Do collages with leaves/flowers etc., found in the yard.
Play tag and play with balls.
Have board games
Teach them how to cook
Do puzzles
Teach them things from workbooks
Get one of those toddler pool things for them to play water games with.

Activities for kids in these age ranges, also means you have to buy supplies and whatnot, to entertain them.

I used to do child care.

Find out what the allegeries are. If peanut butter is ok then peanutbutter and crackers. Rice crispy treats. Fruit bowls. parks and more parks

We just did some water relay races yesterday.I have found lots of fun ideas on pinterest. We've done laserbeams in the hallway, gardening, etc. So fun! We do a lot of pj&j, grilled cheeses, soup, hot dogs, bananas, apples, watermelon, cantelope, carrot sticks, fruit snacks (on occassion). You can find lots of fun toys/games/coloring books at Dollar Tree and the dollar bins at Michaels.

mini golf set
toy bowling set
lots of craft supplies
crayons, sketch pads, coloring books, stickers, sticker books, water color
paints, Matchbox cars, several decks of cards, checker games, building
blocks
buy Lil Tykes playhouse on Craigslist
mini toy plastic kitchen (cheap @ Wal-mart)
plastic toy dishes so they can play kitchen or restaurant
several big plastic kick balls ($1 @ Dollar Store) for outdoor play
easel
plastic shopping cart $9 Wal-mart

Food: crackers, pretzels, pb&j fixings, salami/cheese & crackers, mini turkey sandwiches, mini pizzas, carrot/celery sticks & Ranch dip, healthy-ish cookies. Make sure no allergies to things like peanuts etc.

If you have a good backyard (hope so! with that crew!) get a couple of mini trampolines from Craigslist or Freecycle. croquet set, badminton set, volleyball, something "new" to your yard will be a big hit for a week or two so don't out out everything at once. A tire swing. My husband took the trapeze with handle off the swing set and hung it from a high branch in a tree so it can swing more and the whole neighborhood loves it (ages 5-12)
Water guns, FamilyFun had some ideas for fun back yard stuff....
Froz grapes are fun, frozen bananas make quick smoothies, Joanne's and Michaels have craft ideas, boys will often make bracelets for their mothers if you suggest it. Sidewalk chalk contests with prizes for the most creative, most colorful, prettiest, funniest, etc. If you could get old refridgerator or other big boxes that would be hit!

Tie-dye white t-shirts! Can be done outside, relatively cheap and it's fun! Also, what about a scavenger hunt? Water balloons? Frisbee? Nature rubbings - let each child find an item, leaf or whatever; put it under a piece of white paper and rub over it with a crayon. Fun designs "pop" up!

A fun snack is mini pizzas. Take a roll of biscuits; flatten each one the best you can. Each child can top them with whatever - cheese, pepperoni, etc. Bake them a few minutes and enjoy! (This can also be done with the small tortillas.)

If all else fails, don't you need your lawn mowed, bushes trimmed, weeds pulled!! It can all be made into a game!! Just kidding! Well, sort of!! lol!!

Good luck!!
