Patterns in Addition and Subtraction

This video tutorial explores the concept of skip counting and its application in solving missing number puzzles. It explains how skip counting creates number patterns, both increasing and decreasing, and highlights the connection between skip counting and repeated addition or subtraction. The tutorial also addresses common misconceptions about addition and subtraction being unrelated. Through examples, it demonstrates how to analyze number patterns and use skip counting to find missing numbers, emphasizing the importance of understanding the change in number positions.

What is the main purpose of using skip counting in number puzzles?

• To practice division
