Can you compare objects by characteristics of size, weight, and capacity? 

Detailed explanation for Math Compare size, weight, and capacity

All objects around you have characteristics - weight, length (or height), width, and capacity. Each object has its weight - from a birch leaf to a giant skyscraper. When measuring a thread, we may find only the length. The ribbon has length and width as well. It is possible to define three parameters for the coffee pot - height, width, and capacity. The capacity indicates how much liquid the object may contain. Do you want to determine which of the two containers is larger? Pour water into one container to fill it till the very end. Then start pouring water from this vessel into another until it is full to the brim. There are three possible scenarios:

  1. The second container is full, and the first one still has water. It means that the capacity of the first vessel is larger.

2. The water in the first container has completely fit into the second, but it is still not filled to the brim. In this case,the first container is smaller in capacity.

3. You poured water from the first container into the second without any residue, and it was full. It is an indicator that the capacity of containers are the same.

It is more difficult to determine which capacity is larger from the image of the object. In most cases, the higher and wider the item is, the larger is its capacity.

Comparing the weight of objects, remember everything you know about them. A chicken is smaller than a dog. Therefore, it is lighter. The pillow is made of lightweight material. Even if it is large, it weighs less than a small aquarium with water.

Do you need to determine if a bar of chocolate or a nutbar is longer? Try to find the beginning and end of each object you measure. Connect the left ends of the items and look where the end of the objects on the right sides are. If the right end of the chocolate bar is farther away, then it is longer. We may compare the width in the same way. Also, you may take a ruler, place the left edge at the "0" mark and find at what number the object on the right ends. The larger the number is, the longer (or wider) the item is.
