Just a Minute. Achievement Objective: GM2-1: Create and use appropriate units and devices to measure length, area, volume and capacity, weight (mass), turn (angle), temperature, and time. In these five activities the students develop an understanding of the duration of minutes and seconds. We also practice reading time by counting the minutes after the hour.
