Topic

Addition

Description

Example 11 shows an addition problem (5 + 7) using a number line and regrouping method. A finger points along the number line to add each step, resulting in 12. The tens place has a carryover of 1, and the ones place is 2, giving the answer 12. Example 11. Find the sum: 5 + 7. Solution: Add digits in the ones place using the number line. Use regrouping to put 2 in the ones place and carry 1 to the tens place. shows this in practice.

Teacher’s Script: Today, we are going to look at an example of adding two-digit numbers with regrouping. In this problem, Example 11 shows an addition problem (5 + 7) using a number line and regrouping method. A finger points along the number line to add each step, resulting in 12. The tens place has a carryover of 1, and the ones place is 2, giving the answer 12. Notice how we carry over any values greater than 9 to the next column, reinforcing our understanding of place value.
