I really enjoy teaching my kids math. Actually I teach Kittee and Duncan. Tyree teaches Kathleen and Darien math. This is one of the math books that Kathleen will start using at some point when she grasps fractions and such as that.
One of the reasons I enjoy Ray’s Arithmetic is it’s practicality to everyday life’s situations. It’s one of the best set of Arithmetic books out on the market and should, in my opinion, be embraced by everyone in the US. A second reason that I enjoy teaching my kids with this set of books is that it prepares them to do business. I love that. Math with a purpose!
Look at problem 19. A farmer gave his daughter at her marriage 65 A. 106 sq. rd. of land, which is 3% of his farm: how much land did he own?
For all my math-loving friends and family I’d love to see you work out this problem. You might need some history to figure out this one.
Math is fun when it is done in such a way that there is relevance and order to everyday life.
Here are some interesting facts, I’m embarrassed to say, that I didn’t know. But, hey, maybe you didn’t know this either.
Fact 1. Plus and Minus are Latin words.
Fact 2. Michael Steifel, a German mathematician, first introduced the signs of + and – in a work published in 1544.
Fact 3. William Oughtred, an Englishman, born in 1573 first introduced the sign of multiplication.
Fact 4. Dr. John Pell, an English analyst, born in 1610, introduced the sign of division.
Question- Did you ever learn these in school? Undecillions, Duodecillions, Tredecillions Quatuordecillions, Quindecillions, Sexdecillions, Septendecillions, Octodecillions, Novendecillions, Vigintillions.
Guess what? My spell check didn’t recognize these words as being words either. They show up as incorrect spellings. My post is fraught with red lines. Spell check only considers Units, Thousands, Millions, Billions, Trillions, Quadrillions, Quintillions, Sextillions, Septillions and Octillions, as numbers with correct spellings.
I hope I’ve inspired you or confused you even more than yesterday.
