Subitizing is the ability to immediately recognize the number of a small group of objects without having to count them. The ability to subitize is an essential skill in the development of number sense as children need to be able to relate numbers to actual groups of items quickly. When you download this file you will receive dot cards that can be used either during small group instruction or with your class during whole group instruction to help develop this skill. There are two sets of dot cards. Set 1 contains cards with dots 1-5 to help in the development of perceptual subitizing and Set 2 contains dot cards with dots 6-10 to assist with the development of conceptual subitizing. Specific teaching directions are contained in this file.
