Both are just a part of life. Teach them to calculate the change when they buy something or give them a 1/4 measuring cup and ask them to help you scoop out 1 cup of flour or cereal while cooking (and count out the fractions). Money is a GREAT tool to teach math - 20% off! 5% interest earned! Go to the park to see gravity and centripetal force at work. While you are there test out these theories by dropping a big and small ball from the top of the jungle gym and see which one falls faster (hint: they fall the same). Talk about why. Encourage experimentation! Test the "theory" that microwave ovens heat the water in foods by microwaving a dry and wet cracker to see which gets hotter. Try different variables: crackers, time, etc. Explain what water is made of. Encourage interest in puzzles. Math is just big numbers game (all the way up to calculus), and when you think of it that way, it's fun!
