*Sensational Subitizing
*What is Subitizing?
*Subitizing is the ability to quickly identify the number of items in a small set without counting.
*Researchers have demonstrated a strong relationship between subitizing skill and math achievement including a recent study with over 500 kindergarten students.
*Perceptual Subitizing
*Being able to recognize a number without using any other mathematical process*Subitizing Exercise *Perceptual Subitizing can only occur with
the numbers 1-4 and sometimes 5*After five students move on to Conceptual
Subitizing
*Conceptual Subitizing
*Being able to recognize a number instantly through the use of number patterns. Understanding that numbers are made of composite parts
*Helpful Hints
*The spatial arrangement of sets influences how difficult they are to subitize. *Children usually find rectangular
arrangements easiest, followed by linear, circular, and scrambled arrangements (Beck-with and Restle 1966; Wang, Resnick, and Boozer 1971). *This progression holds true for students
from the primary grades to college.
*Quick Image War
*Person 1 will be the score keeper*Person 2 will flip cards*When signal word is given flip card*If a person says it give them card*If it is incorrect leave card there*When the timer beeps flip next card *Continue until all cards in the flip pile are
gone
*Subitizing Bingo

*Making a Children’s Book
*Think of a catchy phrase the students can repeat when they read your book*Create a Title*Use your subitizing template as a guide*Create 4 pages four your book*You can differentiate the pages according to subitizing
research or make them all one style*Be ready to share your story with the group when done*Be creative
*One StrayTimed Round Table
*When signal is given person 2 in each group will stand up*Each group will beckon for a new person number 2 to come to their group*Person 2 shares their story for 30 seconds*When signal is given person 4 in each group will stand up*Each group will beckon for a new person number 4 to come to their group*Person 4 shares their story for 30 seconds*Person 1 shares for 30 seconds*Person 3 shares for 30 seconds
