Other books has same content, except for the last chapters which are quite cool actually!
I use some of the showmanship tricks from this book to teach math. Math, like any subject, should be challenging, energizing, and fun. I also have been using this book as a prize and reward to motivate young students. The swagger and confidence that they have as calculating squares of two digit numbers in their heads has been fun to watch. That they can beat calculators teaches a self reliance and that a calculator is extra baggage to lug around.
Fourth graders struggle initially, but as they learn their tables, they see the power of being a super brainiac. I have been using the methods in this book as they are learning, to reinforce what they are learning. Young minds are blown as they tie concepts together.
This isn’t a comprehensive textbook, but is more entertaining. It raises the magicians curtain to expose some of the secrets of show exhibition math. After learning single digit multiplication is an ideal time for students to get this book.
A caveat, though, the algebraic proofs will be above their learning, but is also a soft introduction to algebraic concepts. It fits well with how math is now taught.
It’s amazing that all things can be reduced to mathematical calculations! This was very enlightening! Thank you for the insight!
I purchased this a a friends kid, so he can learn during the summer and have fun learning.
