This is where I teach all day.
This is me with my microphone and headset - how I communicate with my students on-line instead of in person.
This one in particular is so interesting.
Here is what they were teaching in Math back in 1931...how to write a check & borrow money from the bank. There is also a chapter on buying stocks. Interesting because the stock market crashed in 1929. I guess educators felt that students needed to learn about proper investing.:)
I'm actually going to read this book over the summer. It is neat.
(In case you were wondering...we've never used these old books as part of our school curriculum)
I love the contrast between teaching the "new" way - virtually and teaching the "old" way - with great text books.
