The Dog Show

There is a dog show today. I will go to the show. I love dogs, said Joseph!

DOG SHOW

Look! Some dogs are long. Some dogs are short.

I want to find the longest dog. Will you please help me?

How can we find the longest dog? asked Joseph. Please help me.

Good! I will measure the dogs. Can I use many different hands to measure? Why or why not?

Our hands are not the same. We need objects that are the same length.

This is our last dog to measure. First lets estimate.

This is the winner! This is the longest dog!

If we used to measure, would we use more or less than the number of cans?
