As an additional activity, you can also use the treasures in math stories. Also, finding a container to hold their objects is actually an exercise in spatial problem solving. You'll probably be needed to provide guidance in this, though, as it an be a difficult concept. If you use the objects in math stories, your kids will be practicing addition, subtraction, multiplication, division, or even basic fractions, depending upon the stories you make up. For younger kids, take all the jacks, queens, and kings out of the deck and create face down piles for each player from the remaining cards.
Players draw cards and compare who has more and less.
For each draw, change the winner from the one who has a higher value card to the one who has a lower value card and ask the players how much the difference between cards is. Deal four cards to each player and have them make as many numbers as they can by adding, subtracting, multiplying, dividing the numbers. Cards are good for this because the abstract number value is physically represented by a number of hearts, diamonds, etc on the card. Both of these activities also provide practice with addition, subtraction, multiplication and division. First, provide your kids with a map of their own for the trip, making sure that it includes a mileage guide or other easy way to determine how much space on the map equals a mile.
