THE ANSWER!!! TIP: If the above example had a list of sums that ended with a 20 *(rather than 19), the list can be added just as the original problem was added so that the student won't have to carry here either. See the sample below. EXAMPLE: 5830 2967 836 + 38567 -------- 30000 15000 3000 180 Here the 80 + 20 = 100. Using 20 the old method of adding, the ------- '1' would have to be carried... 40000 here we just add from left to 8000 right again to get rid of that 100 problem... 100 ------- 48200 THE ANSWER!!! TYING IT TOGETHER: Do math problems and test the kids for speed and accuracy. I usually do a pretest without telling the kids why...having them time the test. I keep this and give it again a couple/three weeks later once they
