In this lesson, I weight various items on a kitchen scale that measures in pounds and ounces. You will see me weighing a box of dominoes, a large container of water, some tomatoes — and even Mathy my mascot! (And he claims he weighs thousands of kilograms... we shall see about that!)
The scale needs adjusted so that the red line is at the zero. This is called the TARE. Some scales have a button for this, but mine doesn't; you have to adjust it manually. So, when we weigh the tomatoes, the empty container is the tare and the scale is reset to show zero WITH the empty container.
Lastly we look at the labels on some food items that show the weight of the item, and we weigh those.
I encourage you to do similar activities at home, weighing various items, including food items that show their weight on the label. Measuring is best learned hands-on!
