The "sense of volume" means the sense of imaging the numbers as the volume.

The whole number is in the following two kinds:
Number as the series (After 1 is 2, after 2 is 3, after 3 is 4, and so goes on)
Number as the volume (1 piece, 2 pieces, 3 pieces, 4 pieces, and so goes on)
The sense-of-volume mental calculation develops a better sense of the "number as the volume". The key to train the "sense of volume" is not to count the number.
You should first become able to grasp and image 1 to 5, and 10 as clusters by just looking at them (not by counting). While imaging 1 to 5, and 10 as clusters, you should image those numbers which are larger than 5 and those larger than 10 by decomposing them into 1 to 5, and 10.
Once you become able to decompose and compose the numbers which you imaged as the volume, you will grow up with the "sense of volume".
