Do you know why pound is abbreviated lb. and ounces is abbreviated oz.? Well I didn't, so we looked it up. In math today we started the measurement for the U.S. customary system and weight. We were talking about pounds and ounces and I wasn't sure why those abbreviations where so much different.
Here is the answer:
The lb. abbreviation originated from the Latin work libra, which means scale and balances.
Oz. comes from an old Italian word onza.
One more reminder too. The Christmas/PJ party is tomorrow. Don't forget to wear your pajamas!
