Understanding the Number Line

The video introduces first-grade students to the concept of a number line, a tool used in math to help with counting, addition, and subtraction. The teacher demonstrates how to use the number line by performing 'bunny hops' to count forward and backward. The video emphasizes the number line's role in learning basic arithmetic operations and encourages students to use it for adding and subtracting numbers.
