Estimating Liquid Volume Concepts

Mrs. Walker introduces the concept of using a vertical number line to estimate and measure liquid volume in liters and milliliters. She demonstrates this with a practical example using water bottles, marking each 100 milliliters on the bottle to visualize the concept. The lesson explains the difference between vertical and horizontal number lines and provides practice problems for students to estimate liquid volume. The video concludes with instructions for independent practice.

What is a vertical number line?

• A number line that is circular

• A number line that goes up and down

• A number line that goes left to right

• A number line that is diagonal

What is the learning goal of the lesson?

• To measure weight using a scale

• To estimate and measure liquid volume using a vertical number line

• To calculate distance using a map

• To understand the concept of time
