PK.N.2.1 Identify the number of objects, up to 10, in a row or column.


In a Nutshell

By the end of Pre-K, students must be able to count and identify how many objects are in front of them from one to ten.  These objects should be laid out in a row or column to help students keep track of what they have counted and what they have not counted.  This skill sets the foundation for subitizing (the ability to recognize how many are in a collection of objects without counting individually).

Student Actions

Teacher Actions

  • Construct understanding by identifying the number of objects in front of them. 
  • Engage in problem solving by using tools and manipulatives like ten frames and counters.
  • Develop reasoning by using manipulatives to represent numbers within rows or columns.
  • Establish learning focus by modeling counting in an organized fashion.
  • Implement tasks that promote reasoning by providing opportunities for students to count objects often. This can be done throughout the day with students, snack, materials for activities, etc.
  • Support productive struggle by providing manipulatives and tools for students to use.

Key Understandings

Misconceptions

  • One to one correspondence. 
  • Number sequence.
  • Counting an object more than once. 
  • Skipping numbers when counting.
  • Arrangement of objects changes the number of objects.
