Showing Your Work When There's Nothing to Show (continued)

While I was homeschooling my children, I found that one of the best tests of whether or not they had learned the material we had covered was whether they were able to teach it to someone else. This was true for math, history, geography and a wide range of subjects. Often, my sons were asked to teach their dad whatever new history material had been covered that day; or they taught their math-phobic grandmother a new concept in that subject.

Until we've created an understanding of different learning styles, we'll have to help our visual-spatial students cope in their predominantly left-hemispheric classrooms by being able to communicate to those who do not think like they do, who do not immediately see the picture (or answer). Teaching them to work backwards will hopefully accomplish this.

First, allow visual-spatial students to perfect whatever strategy works for them in solving their math problems. Then, have them test their methods with a calculator to be certain their answers are correct. Once the students have polished their own unique systems, gradually increase the difficulty of the problems to continue to test their methods. Once they have consistently answered the problems correctly, using their own strategies, show them how to work in reverse. In other words, they can continue to use their methods (so long as they produce accurate results) to arrive at an answer and then they work backwards through the problem to show the details to someone who needs to be shown the steps, or "work."

For example, in the long division problem below, let's suppose that the student, using whatever mental or written method this student has created, arrives at a solution and has proven it is correct by double-checking the answer with a calculator.

         26
15) 390

Now that the answer is known, the student simply works through the solution to show the steps. So the first "work" to show is 15 x 2. This answer is then written directly under the 39:

         26
15) 390
         30

Next, show the student that auditory-sequential learners can't just hold numbers (or other images, for that matter) in their head as easily as visual-spatials do, so the next "work" to show is to subtract the 30 from 39 and bring down the next digit:

         26
15) 390
          30
         90

The student doesn't need to figure out how many times 15 goes into 90, because he or she already knew (saw) that! It must be 6. But the auditory-sequential thinker will need to be shown, so just write out the last bit of work:

         26
15) 390
          30
         90
           90  
         0

While it may seem obvious to the student, the last number showing in any problem such as this must be 0 or the work has not been shown in a manner in which the teacher, or another auditory-sequential learner, can follow.

By working backwards through problems, in math and other areas, too (creating an outline of a report after the report is written qualifies as working backwards!), visual-spatial learners can demonstrate the steps of their work so that the auditory-sequential learners they must communicate with (primarily teachers) can understand exactly how they arrived at their answers. By opening the doors of communication and demonstrating their work in a manner that can be interpreted by sequential thinkers, they can receive grades commensurate with their abilities.
