*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.

*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
