Okay, I admit it, I personally love math. I have, on occasion, been called 'a human calculator'.
These super cool self-checking flashcard books from innovative KIDS make math fun for everyone, I promise!
The books come in four versions; Addition, Subtraction, Multiplication, and Division.
Each book starts and finishes with 'Fun Facts'.
The book I am using for demonstration purposes is the Multiplication book, the 'Fun Facts' that it includes are:
Multiplication is just another way to write addition;
3 x 4 is the same as 3 + 3 + 3 + 3 or 4 + 4 + 4.
The numbers in the two-digit products of the 9 times table, all add up to 9:
9 x 2 = 18...1 + 8 = 9,
9 x 3 = 27...2 + 7 = 9,
and so on.
To multiply any number by 10, just add a zero to the end of it! For example:
3 x 10 = 30
12 x 10 = 120
137 x 10 = 1370
To multiply a number (up to 9) by 11, just write the number twice! For example:
3 x 11 = 33
7 x 11 = 77
The genius part about these books are the slide wheels. You simply turn the wheel clockwise to create the desired equation.
What's the answer? Think you have it? Check under the ? flap.
When you flip through the book from 'front to back' you get the equations for odd numbers 1 through 11, and when you flip through the book 'back to front' you get the equations for even numbers 2 through 12.
These books are great to use with your kids as an alternative to flash cards. Kids can use them with your help or even by themselves.
Since they are bound in a book format, there are no cards to lose!
