How Long is it?
In this unit students
• use tools to measure length;
• estimate length;
• represent length measurements in a line plot;
• representing numbers on a number line.
This unit focuses on measuring length in standard units and uses the concept of length to represent whole numbers on the number line. In Grade 1, students measured length using non-standard units. In Grade 2, students work with rulers, yardsticks, meter sticks, and measuring tapes in order to determine length. Students also use measurement of objects to create line plots.
