Cleaning involves the whole family. Start a game that whenever your child enters a room, they have to pick up and put away two objects. Invent other "rules" to make chores fun.
Locate a museum in your area that's free or low cost and learn something new this weekend! Draw a picture with your child about your favorite discovery.
Enjoy tea or hot cocoa this weekend. Have your child guess what temperature they think their drink is and then show your child how to check it with a thermometer.
Nothing's better on a cold day than warm cookies! Ask your child to help you measure ingredients and mix them together. Praise them for being a great helper.
