I need help please!!!!?

I'm 15 years old, and I am babysitting tomorrow night for a family with three kids. A boy who is 11, and two girls that are 6 and 5. Could anyone give me some tips as to what to do with them? Also, should I charge per kid? I usually work for $5 and hour with one child. Any ideas or tips? I would appreciate it.
They are very good kids as far as I know. My mom had the two girls as students, and my sister was in class with the boy.
For those of you who say I am not of age, it is not an actual job. And where I live, anyone 14 and over can be alone at home with a child. Also, if you are going to give me an answer to a question I didn't even ask, don't bother even answering at all. Another detail! Haha. Okay so I'm not as concerned with the money because I don't really need it. Not to sound cocky, but I'm only doing this to help thes people out. Their father is really sick, but they insist on paying me. So, to rephrase my question, how much do I ask them to pay me without being too harsh?

Since you usually charge $5/hr for one child, you could charge anywhere from $7 to $10/hr. If you go low on that, tell them you're giving them a special discount.

Ask them if they like playing games, like card games (go fish, uno, etc.) or board games or other games. Some families teach their children to enjoy games; others don't.

In summer, painting is always fun. I used to mix kid's powder paints with soap gunk I created by soaking my leftover soap slivers in hot water. This prevents stains setting in the clothing. I also got pieces of press-board which is compressed wood and water doesn't absorb into it. I let them finger paint on those so they could change the painting as often as they wanted. If it started to dry, we just dribbled a little bit of water on it. When they got a painting design they specially liked, I had a roll of butcher paper or newsprint I'd gotten from the newspapers for free. I'd cut a piece of paper for them to press down on the favored design, then they'd rub it to make it pick up paint print on the paper. This way they made LOTS of designs, and only a few final prints.

Crafts are always good to do with children and can be done with the boy's age as well as the girls' age. If you were 18 I'd suggest candle making, but that can be more dangerous so I don't recommend it at your age. You can teach them how to do collages, and one day the collage could be macaroni and beans and other food items. Another day it could be pictures cut out of newspapers and magazines.

You want crafts that aren't too hard for the girls and too boring for the boy.

Also, ask them what games they like to play... inside and/or outside.

If the family says it's ok, nature walks would be great. Maybe one day you could do bird watching and another day see what insects you can find and identify.

We used to play hopscotch!
We used to roller skate...

You can do a google search for "games for kids/children" or "entertaining children" or "crafts for children" for more ideas.

Have the kids brainstorm with you to get an idea of what things they'd think up that they've not tried or have tried and would like to do.

Good luck.
