Bruce the Bobcat has a new challenge.
"I found 42 pinecones," says Bruce.
"Bennie found 27. Who found more?"
Bennie the Bear looks at the tens.
Learn it: tens first
Bennie builds both numbers with blocks.
42 has 4 tens. 27 has 2 tens.
4 tens are more than 2 tens.
So 42 is greater than 27.
Bruce found more pinecones. Good counting, Bruce!
