Error Patterns in Computation. Whole Numbers: Addition and Subtraction

One of the error patterns I have encountered is that students forget basic addition, especially for additions involving whole number 1 to 9. For example, when one of the addends is 0, I have seen some students put 0 as the sum, which is obviously a rule for multiplication. Some consider adding 0 as similar to adding 1 to the other addend, thereby increasing the number by 1. Another common error I have encountered is when students add a multi-digit addend to a single-digit addend, some calculate for the sum of the individual digits together. Some add the single-digit to each of the digits of the multi-digit addend. Some get confused with place-values, thus adding the ones to the tens, and so on. Some even make up a new rule in addition by adding all the numbers in the ones position then placing the sum under the tens. This is followed by calculating the sum of all the numbers in the tens position, and then placing the sum under the ones. ...Show more
