Jen and Maria baked cookies together for the school bake sale. They placed all of the cookies in a large pile to cool during the night so that they could pack- age them in the morning.

During the night, Jen woke up hungry. She went to the kitchen and ate two of the cookies that they had made. She then divided the rest of the cookies into two even piles. Jen took one pile and placed these cookies in a cookie tin which she hid in a cabinet before going back to bed.

A short time later, Maria woke up and went down to the kitchen. She ate two cookies because she was hungry, then split the remaining cookies into two equal piles. She put one pile in a plastic bag to take home for her family and hid it in her backpack before going back to bed.

In the morning, the girls were surprised to find only 10 cookies left in the pile for the bake sale. “I only ate a couple of cookies because I was hun- gry,” said Jen. “So did I,” said Maria. “Well, we might as well split the rest,” suggested Jen. “Okay,” said Maria, “and then we can get started baking more for the bake sale.”

Three monkeys lived on an island and hunted for food together. They put all of the coconuts they found in a large pile and went to sleep.

During the night, the first monkey woke up hungry. He ate one coconut, then he divided the rest of the coconuts into three equal piles. He pushed two piles back together, then took the third pile off into the forest to eat some more before returning to bed.

After a short time, the second monkey woke up hungry and went to the pile of coconuts. He ate one coconut and then he divided the rest of the coconuts into three equal piles. He pushed two piles back together, then took the third pile off to the beach to eat some more before returning to bed.

Soon, the third monkey woke up, went to the pile of coconuts and ate one coconut because he was hungry. He divided the rest of the coconuts into three equal piles. He pushed two of the piles together then took the third pile back to his favorite tree to eat some more before returning to bed.

In the morning, the three monkeys went to the pile of coconuts and were surprised to only see 6 coconuts left. “I know there were more than this yesterday,” said the first monkey. The other two monkeys nodded in agreement. “I only took a couple last night,” the first monkey said. “I only took a couple last night,” the second monkey echoed. “Me too!” said the third monkey.
