The Energy Guy Does Rounding For 3rd Graders

I was recently asked to make a short video for children 8 – 9 years old. The subject was to involve how I use rounding in my job.

I chose to use measuring a house to obtain the size in cubic feet and relate that to choosing the size of the furnace. I varied the measurement on each side of the house by 6 inches.  The measurement rounding was shown to be accurate enough for this need. In this case the accuracy requirement was not needed due to furnace engineering issues, not the ability of someone to measure to the nearest inch or 6 inches.

Enjoy the video – help some kids! Thanks to the Third Grade Teacher, Grace for including me.  Here is the video on my You Tube Channel
