1. Activate students' prior knowledge.
Explain to students that, millions of years ago, the oceans were full of incredible sea creatures, or marine reptiles. Some were very big. Some were fast swimmers. Ask: What sea creatures might you encounter if you traveled 82 million years back in time? Display the Sea Creature Trading Cards and have students preview them. Ask: What do you already know about the six sea creatures on the cards?
2. Have students find facts about sea creatures and complete the cards.
Divide students into small groups. Print and distribute one copy of the Sea Creatures Trading Cards for each group. Then, have small groups use the Sea Monsters website to find information about their sizes, as well as fun facts about each. Have each group work together to complete the cards with the information.
3. Have small groups trade and compare cards.
Allow groups time to trade and compare cards. Then have a whole-class discussion. Ask: Did other groups find any fun facts that you didn’t? Have groups add to their cards as they hear new information.
