Understanding the Arrow Method

The video tutorial introduces second-grade students to addition and subtraction strategies using the arrow method and number line. It explains how to break down numbers into tens for easier addition and subtraction, demonstrating both forward and backward counting. The tutorial emphasizes flexible thinking and multiple problem-solving approaches.

What is the main focus of the video tutorial?

• Multiplication strategies

• Second grade addition and subtraction strategies

• Division techniques

• Geometry basics

In the arrow method, how is the number 40 broken down for addition?
