Speedy Pictures II

Students can use this interactive applet to practice quick recognition of the number or value of a small group of objects, without one-to-one counting. This skill, called subitizing, is important in the development of number sense. The user chooses among several representations, including fingers, a pair of dice, an abacus, a ten frame, and coins. In this version of the game users score points according to how quickly and accurately they complete each round of ten examples.

      Structuring
      By kjstuttgen on 12/04/2012 - 20:33
    • In Math Recovery, this is called structuring or subsitizing. It helps students to break apart numbers in different ways. This site differs from Speedy Pictures 1 because the picture is not flashed. You cannot set a certain time limit for the pictures. This is helpful for introducing at the K level where they need to study the pictures to see groups or for students who are proficient in structuring and want to race to see how many they can get.
