Topic

Addition

Description

Demonstration of adding 2 + 17 with a number line. The finger counts from 7 to 9. The example includes a visual breakdown of the tens and ones places for clarity on addition without regrouping. Example 36. Find the sum. Use the strategy of counting on with a number line to find the sum. Add the numbers in the ones place. Since there is no regrouping, bring down the value in the tens place. The solution is 19.

In general, addition is a fundamental arithmetic skill that helps students understand the concept of combining quantities. Through these examples, students can see how basic addition works with small numbers, building a strong foundation for more complex operations. By visualizing the steps, students can reinforce their understanding of number relationships.

Seeing multiple worked-out examples allows students to recognize patterns in addition. For instance, consistently seeing sums calculated on a number line or through other visual aids enables them to approach addition with confidence. Reinforcement through examples is essential for deep comprehension and retention of the concept.

Teacher’s Script: Today, we’re looking at an example of adding numbers. In this case, let’s focus on example 36. find the sum. use the strategy of counting on with a number line to find the sum. add the numbers in the ones place. since there is no regrouping, bring down the value in the tens place. the solution is 19.. Notice how we carefully add the numbers step by step. Think about how each example builds on what we’ve learned before.
