3rd Grade Addition Of Number Game - 1 to 100 - 3rd grade is when things get more complicated and harder. Students may experience that their lessons are more advanced now. A third grader's addition of numbers may actually be up to a hundred. Now, this is something that is rather new to some students that are not very familiar with addition or just don't like math in an overall manner. But adding numbers up to 100 is an easy task, it's just like adding single-digit numbers, too. For example, adding 99 to 65. We would, of course, line them up according to their place value. Once that that has been done, we could now add them together, but you don't add them as is. You will add them by column; therefore, you add 9 and 5 together on the first column then 9 and 6 on the next one. This is why the addition of numbers is not really that hard nor complicated, it may seem confusing at first, but addition is just adding numbers with a single digit depending on what method they are going to use. The only catch on this type of addition is that the learner must also know how to do the regroup and carry numbers to the next column.
