### Three-Digit Addition

After your students have mastered two digit addition, get them going on three digit addition by incorporating worksheets that not only keep learning fun but help keep everything in order. It’s easy for students to get confused when working on addition problems that incorporate multiple digits, but these worksheets will lay out everything clearly and keep everything organized when teaching three digit addition.
Multi-digit addition is the first thing early learners will do that will break out of something they can do on their fingers. This will be their opportunity to use mental math and the addition within 10 that they’ve memorized in order to solve complicated problems.
There are multiple ways of solving three digit addition problems. One of the foundational concepts behind our learning system is to approach problems from different directions. This increases understanding and number sense. Practicing these methods using the resources provided by Education.com above may help students gain proficiency in three digit addition.
Break Apart
If your student is attempting three digit addition, they should already have a good grasp of addition up to 10. The break apart method uses this foundation by breaking the numbers into whole hundreds, tens, and ones, then adding those individually. Each of these individual problems can be done as a single digit problem, simply adding the zeros on afterwards. The sums are then added together to get the final sum of the original problem.
Number Line
Using a number line is similar to the break apart method but also helps the student visually understand how the numbers are increasing. In order to use the number line method, students would draw a number line and write one of the two addends at the starting point of the number line. Then they will jump forward once for each hundred, writing the new number on the number line. This process is repeated with the tens and ones until the final sum is reached.
