4. Introduce  Using the playing cards, you and a partner are going to play a game.  Each player must draw 5 cards from the pile one at a time.  Place each card face up so that it makes a 5-digit number.  Compare your numbers. The person with the greatest 5-digit number wins.  Example: Natalie picked a 4, 7, 1, 3, and 5. Soumya picked 2, 6, 8, 1, and 3. Who has the greatest 5-digit number? Write your answer as a comparison.  Emma; 47,135 > 26,813  Try to play 5 rounds.  Using the playing cards, you and a partner are going to play a game.  Each player must draw 5 cards from the pile one at a time.  Place each card face up so that it makes a 5-digit number.  Compare your numbers.
