Quick images or dot images help children subtitize (develop automaticity with number and quantity - basically seeing four items and knowing there are four without counting). I have included two links to help demystify subtitizing.
This link is from Pre-k Pages - http://www.pre-kpages.com/subitizing/
Pre-k Pages provides a simple definition and easy activities to try either in the classroom or at home!
If you would like to delve a little deeper into the world of subtitizing, I would suggest reading the following article: Subitizing: What is it? Why Teach It? By: Douglas H. Clements. He is a professor at the University of Buffalo and has written over 100 research articles! WOW!
Clements suggests an activity, that helps develop patterning skills and listening skills. He suggests invloving auditory rhythms with numeral writing activites. For ex., ask your students to listen for the number of rings on a bell before writing the number down. What a great idea! http://teacherweb.com/WA/nachesvalleyprimaryschool/msclark/Subs.PDF
For a printable to work on quantities up to five head over to Printables and download a five frame with a dafodilly - have been dying to record my oldest love buggian's way of labeling daffodils! Actually it isn't a daffodil! The clip art is a beautiful spring flower to brighten your day!
