Cut up some plastic cups, put a sliced balloon in the top and add something to shoot (marshmallows, pompoms, paper balls, Legos, etc) This is great for a child's pincer grip as well as hand-eye coordination. Put a bucket on one end of the bathtub during bathtime and make this is great game for them. 

Here is an easy and inexpensive way to make a game at home. Just a few paper plates (which your kids can color) along with a paper-towel roll. Have the kids play in a long hallway or in their rooms. 

Save your toilet paper rolls and go find some twigs!! Actually, you can also do this with bottle caps, pompoms, crayons... etc. This is a great way to help kids learn how to count. Make it extra challenging by having the twigs at one end of the stairs and the buckets in the other, so they get a workout at the same time. :) Other great ideas can be found on pinterest.com

Have kids use rulers and measuring tape to measure things around the house. This can keep them entertained for quite some time and make sure they're engaged at the same time. It's a great way to practice math as well as identification. Want to make it a little harder/ more educative? Have the pictures with words in another language, for them to learn. Try Spanish or French!

This is a great activity that can be done anywhere. Put it into a ziplock bag and have kids entertained in the car, they won't even know they're working on their fine motor skills. You can further adapt this by having them match numbers or shapes.
