I'm going to TRY to post a week or so worth of ideas each week or so. 
But you know how it goes.
Try to adapt my ideas to your family and the ages of your kids. I will TRY to make a suggestion that covers more then one age group where I can and welcome you to add your thoughts so I can learn ideas too.
Game Night: For birthdays and Christmas a board game or card game, per kid and soon you'll have enough to avoid the "I'm Bored" phrase. The kids learn from it. They get counting skills, people skills, and even moral skills and they don't even know it. Pull them out on a rainy day. Or make them a tool to do one on one time. My older girl and I do them after the little ones head to bed.
As a family time tool you can even add a bit of popcorn and try for a game that covers every age group.
Funnies: (A great public or car game) Tell a story a bit at a time. One person starts it and "passes" it to another. The more parts the sillier it tends to get.
No major rules to this game... until you make them up. As the kids get better at it, you can change things up a bit. Make it themed, like about animals,, colors, or sports. You can make it so each person has to work a certain word or phrase into it. The ABC's are fun to work into the rules too. Each person has to start off with the next letter in the alphabet.
We limit the number of sentences each turn has. It depends on who's playing because some ages are better then others.
Manners: Day One: Make a list of Good Manners with your child(ren). Write two copies. One to hang on the wall, another for a chart for each child. Remember to keep it light and fun.
Day Two: Ask the kids to put a check next to each good manner that they use today. At the end of the day count them up. If you must open your mouth, remember to be nice.
Day Three: Look at the Manners Chart. Talk about what manners were used the most and which were used the least. Talk about how the child can work on improving.
-When I did this, we adults were to keep track too. We had to use the check marks and talk about it too. We also kept the charts active for a month, Count checks before each night's story, talking about improving and improvements Friday before bed. Remember to keep it light and fun... that means no major criticisms or "chores" attached to it.
Toes and Shoes: This game shows size relations and such and can be adapted to older kids by adding cutting or decorating to the directions.
Take a good size sheet of paper and trace your child's foot. Then Using a different color trace their shoe with the foot tracing under it.
Do the same with your feet and shoes.
A way to expand this is to trace each family members shoes and feet. Cut them all out. Now you can take turns matching the foot to the shoe, the person to their item, or all three.
