Unit 05: Similarities Pre-K

Compare, Contrast, Similarities and Differences

Comparison and contrast help children to build strong mental structures because they lead children to examine more closely the events and concepts and to identify those aspects that differentiate one from another. This effort increases the number of logical connections with the structure of the ideal concept that the child is learning.

The first step is to recognise two or more concepts or objects and identify what characteristics they have in common, listing them in a column. The second step is to identify te major differences between them, and again listing them in a column..

Comparison is the process of identifying how things are alike and different. Comparing promotes vocabulary development and develop higher thinking.

Parents can teach their children comparison and contrast in everyday life.

Example: What are the similarities between cup and glass and what are the differences?


  • Both might be made of the same material
  • Both can use for drinking
  • Both might be fragile


  • Cup is smaller than glass
  • Glass usually use for drinking water and cup usually use for drinking tea or cofee.
  • Cup usually have handle but glass usually don’t have handle

If this simple way parents can train their children, they will build up a habit to make compare any concept or object whatever they see it or know it.
