Kindergartners measure the lengths of common classroom objects. They use standard and non-standard measures. The little ones should love this lesson because they get to use tape measures, rulers, yardsticks, scales, clocks, calendars, and thermometers. After listening to the book Twelve Snails to One Lizard, youngsters get into groups and practice using their tools of measurement. The lesson will require quite a bit of parental, teacher, or big buddy help in order for it to be a success.
