Speedy Pictures 1

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 an adjustable timer determines how long each group is visible. The applet keeps score of the number correct in each round of ten attempts.

      Structuring
      By kjstuttgen on 12/04/2012 - 20:29
    • In Math Recovery, this is called structuring. It helps students to break apart numbers in different ways. This one differs from Speedy Pictures 2 because you can set it to flash the picture for various increments (seconds). Then you can repeat the picture in case students missed it.
