In this lesson, students shall apply the concept of measurement to solve problems involving two- and three-dimensional shapes by demonstrating an understanding of measurement, given familiar objects, to identify type of measurement required, estimate measurement, select appropriate tools and units of measurement, measure accurately, and use measurement to order a group of objects according to size. This lesson includes hands on activities that gives student the opportunity to use a ruler and record their findings. Students will learn that a ruler is marked with numbers, that each number represents a unit of measurement, and they will be able to use the ruler to measure objects in the classroom. Song can also be used with this lesson to help students remember that the Ruler is the king of measurement.

8) Go over students findings together listing measurements in order from smallest to largest.
9) Close with the song.
Select three objects. Place in front of classroom. Have each student, taking turns, measure one of the items of choice, record the results on the bottom of their data sheet and hand in the paper.
