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 23: find the sum of 1 + 14 using a counting-on strategy with a number line. since there is no regrouping, bring down the tens place. the result is 15.. Notice how we carefully add the numbers step by step. Think about how each example builds on what we’ve learned before.
