Adding 417 + 268 Using Traditional Algorithm

This video illustrates how to use the traditional addition algorithm with regrouping. The traditional algorithm focuses on digit placement and requires that students move right to left to correctly perform the operation. Before students are introduced to the standard addition algorithm, it is important that they have a conceptual understanding of regrouping. This will allow students to correctly use the algorithm when they need to exchange 10 ones in the ones place value column with 1 ten in the tens place value column.. It is important for students to know and understand how to use the traditional algorithm because it is an efficient strategy to use if regrouping is required, when numbers have varying numbers of digits, and when the numbers included are too large to reasonably use other strategies (i.e., adding several numbers of large value is cumbersome with base-10 blocks).
