Its easy to make math fun.  While driving down the road you can count the cars/trucks. Compare how many cars to trucks....which was more or less. At home you can count almost anything from cans of food, to coins, to picture frames.  Make it interesting by turning it into a problem solving situation like....."If I have four cans of green beans and you have three cans of corn, how many cans of food do we have all together?"
