Subitizing, or quickly recognizing the quantity of objects in a group without having to count, is an important number sense skill. Practice recognizing the number of dots in a variety of pattern types including from 1 to 10 dots. Dice patterns and patterns based on 10-frames are included. Patterns are made with one or two colors. Set the length of time a pattern is shown and the range of dots displayed. The iPad version also incorporates up to 20 dots and two 10 Frames
Pattern Sets is one app in the NumberSense series designed at Augustana College in Rock Island, Illinois for K-2 grade students. In addition to the support website, see www.augustana.edu/numbersense for information about the project.
