Estimate to Add Multi-Digit Numbers
234 + 127
Unconscious, Incompetence: “I think I am supposed to add these numbers.”
Conscious, Incompetence: “I know this has something to do with rounding, but I can’t remember the rules I learned last year.”
Consciously, Competent: “My answer will be incorrect if it is the exact sum of the numbers shown. In order to find the answer, I will round the given addends to numbers that are much easier to add. Then I will find the sum.”
Unconsciously, Competent: “Estimate means to round. I will round both numbers and find the sum.”
Consciously Masterful: “Because I am being asked to ‘Estimate to find the sum,’ I know I have options. I can either estimate using rounding or use compatible numbers. There is more than one correct answer to this problem.”
