Description
The aim of this paper is to investigate whether elementary school students canunderstand the number of digits of “big numbers” such as “one million” and “one billion” with help of the property of “logarithm” and the learning tool called “KEISANJYAKU”. To confirm the usefulness of the “KEISANJYAKU”, we first carried out the classes practice on the property of logarithm with “KEISANJYAKU” which can count the number of digits of “big numbers” in a class of high school as connection to classes at elementary schools.
