Captain Coral and Wanda compared treasure amounts. "I have 462 coins and you have 489," said Captain Coral.
"To compare, start at the hundreds," said Wanda. "Both have 4 hundreds. Move to tens: 6 tens vs 8 tens. 8 is greater, so 489 > 462."
Captain Coral tried 735 vs 729: "7 hundreds = 7 hundreds. 3 tens vs 2 tens. 3 > 2. So 735 > 729!"
"Always compare from left to right: hundreds first, then tens, then ones," said Wanda.
