Read this part before doing any problems:
Near Hawaii, dolphins and humpback whales have been seen interacting in a fun way. The dolphin rides on the whale’s back as the whale surfaces and then the dolphin slides down the whale’s side. They will do that together over and over.
Level 1: Side to Side: If the dolphin first slides down the whale’s left side, then its right side and keeps alternating sides until it has slid down 7 times, how many times did it ride down the right side.
Level 2: Hey, Little Buddy: The 12 foot dolphin is 39 feet shorter than the whale. How long is the whale? Draw a picture or a bar model to help you. Bonus: If you lined up the dolphin and whale end to end, how long would they be altogether?
Level 3: A Weighty Whale: The humpback whale weighs 66,000 pounds. If the whale weighs 100 times more than the dolphin, how much does the dolphin weigh?
