Mrs. Spence’s Class

Today we reviewed measurement in a new way….

We took different size boxes and found a lot of ways to measure them.

First, we located the base of the box. (The base is what it sits on.) Next, we measured the length, the width, and the height. (If it was a fraction, we rounded up.) Then we were able to find the volume (l x w x h). After that, we found the perimeter of the base (s + s + s + s) s= side. Finally we found the area of the base (l x w). After we completed one box, we all switched and measured our second box. The boxes were all different sizes - some with lids, some with out. We discussed that having a lid didn’t affect the measurements. After working with 5 boxes, we all had a chance to use our customary rulers and practice finding different measurements.

Words to remember:

* area - length x width (l x w ) - it’s like putting down carpet or tile on the floor, covering the base

* volume - length x width x height (l x w x h) - it’s like filling up the shape with water or blocks all the way to the top (that’s why you need the height measurement)

* perimeter - side + side + side + side (s + s + s + s) - all the way around the sides
