    Look for the bar that is the next longest after the longest bar.

For parents and guardians

  • The names of lessons and the order of topics differ slightly between textbooks. This page follows the content of Japan's national curriculum guidelines (the Course of Study).
  • When reading a bar graph, building the habit of first checking what one division stands for makes it less likely to misread graphs where one division is 2 or 5.
  • Try making a table of your family's favorite foods or the weather for one week, and then drawing a bar graph. Your child can experience the flow of organizing and showing information.
