# 21 Club

• Be Part of the 21 Club!!

Memorizing your multiplication facts is one of the most important things you will need to know as a fourth grade.

Knowing the times tables will make your life much easier in the future.  It’s true!!  Do yourself a favor and become a member of the 21 Club!

-         If you can skip count by 2s then you know your 2 times tables

-         If you can skip count by 5s then you know your 5 times tables

-         If you can skip count by 10s then you know your 10 times tables

Also…

-         Everything multiplied by zero is zero.  Ex:  0x3=0

-         Everything multiplied by one is itself.  Ex:  1x5=5

So…you already know 0,1,2,5, and 10 times tables!  This leaves you with only 21 facts to memorize!  Here they are:
