Japanese Method Of Math

Teach them how to use japanese multiplication method.

Japanese method of math. Draw sets of parallel lines representing each digit of the firs. Pupils are taught this method in japanese primary schools at a very early age to develop the ability to multiply large numbers. Here are the four basic mathematical operations 加減乗除 kagenjojo or かげんじょうじょう in japanese. Today let s go through some basic math together.

I m going to tell you how to read each of these equations in japanese. Each cluster of intersections corresponds to one of the four smaller products that go into multiplying two numbers for instance the left cluster 3 1 is what gets you the 300 or 3 hundreds. The japanese method has proven very popular from the retweets and the feedback i have received from fellow practitioners. In order to understand how japanese multiplication works we must start back at the good old reliable method of organizing equal groups in rows and columns.

You re right i m talking about an array. When we say 3 times 2 that is the same as saying 3 groups of 2 and we can show these three groups as 3 rows and 2 columns or 3 columns and two rows. Here is an interesting method to visualize multiplication that reduces it to simple counting. The japanese multiplication method is really just a visual way of representing those four steps.

This visual math trick lets kids use lines and their intersections to see how math works and helps show that math and numbers can be fun. However you never know when you ll need to do quick math and the japanese multiplication method also called multiply by lines can help you figure out the answer simply by counting.
