OBJECTIVE: Problem Solving. ACTIVITIES: On the twelfth day of Christmas my true love sent to me: 12 drummers drumming, 11 pipers piping, 10 lords a leaping, 9 ladies dancing, 8 maids a milking, 7 swans a swimming, 6 geese a laying, 5 gold rings, 4 calling birds, 3 French hens, 2 turtle doves, A partridge in a pear tree. You will find that the number of gifts to arrive on the 12th day is:
12 + 11 + 10 + 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 78
If no gifts are thrown away or given away during the 12 days, how many gifts will there be at the end of the song? NOTES: List all calculations carefully and explain your work. HOMEWORK: None

Label Shuffle

I have three containers. One has only red marbles, one has only blue marbles and the third has an equal number of red and blue marbles. The labels on the containers have intentionally been switched so that each container is now marked incorrectly.

Your job is to relabel the containers correctly.

Of course you could just look in each container to find out which label matches each container, but can you do it with out looking in each container?

Reach into any of the containers and select one marble. Can you now correctly label all three containers? If not, select a second marble from any container. What is the fewest number of marbles you need to inspect in order to correctly label each container?

Be sure that you consider all possible outcomes in your explanation.
