A boy was once given a dollar by his father. His sister very nicely offered to make a sacrifice trading him two shiny quarters for his one rumpled dollar. Repeating this logic with his brother, and later with classmates at school, he increased from two quarters to three dimes and finally ended up with five pennies.
What have you done with the gifts your father has given you?
What will this boy do when his father offers to trade him a new dollar for his five precious pennies?
