Welcome to the Secret Code Math BookKids need to master basic operations, including addition, subtraction,

multiplication, and division. The only way to do this is through consistent,

repetitive practice. Unfortunately, most drill-and-practice worksheets are dull and

tedious for students to complete.

In an effort to make math practice more fun, I have developed two printable

eBooks filled with math worksheets that seem more like puzzles and less like

math work.

The first book, Math Riddle Book, was released in 2007 and has been a huge hit

with students, parents, and teachers. It features corny, laugh-out-loud riddles

that kids love! Kids can unlock the answers to the riddles by solving a set of Math

problems.

The second book, Secret Code Math, is the one you're reading right now. The

worksheets in this book feature a symbol key that kids must use to decode the

numbers in a math problem before they can find the answers. In addition to

teaching math skills, Secret Code Math helps kids build concentration and logical

reasoning.

I hope your students enjoy learning from the worksheets in this book.

Sincerely,

Tim WeiP.S. Please, if you have any questions, comments, or suggestions, please feel free

to e-mail me. My address is: [email protected]
