Kumon Puzzle Intellectual training Concentration and work skills Step 5 3 pieces （ 96 ， 117 ， 140 pieces ）

This is a Kumon puzzle. When I attended Kumon in Japan, I got hooked on them in the classroom, and my teacher recommended them for my home use as they helped me develop my concentration and fingertips （ about 3000 yen ）.
As I got used to it, I worked on it while measuring and recording the time as instructed.
I enjoyed the game of increasing my speed, so I never got bored, and as I got better at it, I moved on to the next level.
