2. Color the blocks on your paper to match the !

Which block is taller?

3. Indirect comparison
If we put the green block next to the black block, !
Which one will be taller? How do you know this?!
Take a moment to think about this before you write your answer.

5. While he was there he noticed his cousin’s new shoes. !
He wanted to know which was bigger, his cousin’s shoes or !
a pair of shoes he left at home. Since he didn’t have his!
shoes with him, he measured his cousin’s shoe !
with his forearm.!
What do you notice when you compare Wyatt’s!
forearm to the blue shoe?

6. When Wyatt got home, he measured his!
shoe with his forearm. !
What do you notice when you compare Wyatt’s!
forearm to the black shoe?

7. Which shoe is bigger, the black one or the blue one?!
How do you know?

8. Wyatt wants to sort his toy cars from !
shortest to longest. Be knows that the gold!
