20+ Resources for Classification and Categorization

One of my favorite sorting activities was to classify and categorize buttons.
We sorted by size, shape, the number of holes, and texture.
However, the favorite category was buttons that spin

The terms classify and categorize are often used interchangeably. The Merriam Webster Dictionary identifies classify and categorize as synonyms and the definitions were very similar. I found several other definitions of these terms showing definite differences, but the best explanation, below, comes from a Roanoke County Schools web page
  • When you classify, you group together several things that have something in common.
  • When you tell how the parts of the group are alike, you categorize them
When we teach children to group or sort objects, both classification and categorization are usually intertwined into our activities. 

Here are some FREE or very inexpensive activities to use when teaching classifying and categorizing.
