   In this lesson we will see how and why objects may be sorted, classified, sequenced or patterned.

  Let's look at these objects.  

What would be the best way to sort these? 

The objects were sorted and placed in 2 separate groups.  The suns and moons are 2 different kinds of things.  The moons are in one group and the suns are in another group.

Let's look at these things. 

   This is how I sorted the ducks.  I looked at the sizes.  I put the big ducks in one group and the little ducks in another group.
