Counting by ones from one is a skill that children develop early and use in many situations. Primary-grade teachers encourage their students to count to find out how many objects are in a set. Such counting is helpful in determining answers to introductory addition and subtraction examples. After an understanding of these two operations has been developed and the basic addition and subtraction facts have been introduced, however, the “counting by ones from one” skill that children have can become a liability. Many students 6 use the method, since it almost guarantees a correct answer, but such counting is very inefficient if students use this method to find every answer. |
