Multiplying 9's

I have come across several neat ideas for Multiplying 9's that I have used in tutoring that I thought I would pass along to all of my wonderful blogging friends.


Picture above is using Digital Paper from Ashley Hughes and Clip Art from Teachers ClipArt.  Thanks ladies!

The first one is one that I used to use as a child.  When multiplying anything times 9, the sums always equal 9.  Example: 9 x 4 = 36, 3 + 6 = 9.  9 X 8 = 72, 7 + 2 = 9.

The next trick the child actually most came up with his on his and my light bulb went off and figured it out.  If multiplying by 9's think multiplying by 10's and then count back the other factor.  Example: 9 X 6, think 10 X 6 = 60 subtract 6 and you get 54 so 9 X 6 = 54.

The 3rd trick I found online and uses your hands.  This to me is the simplest easiest way to learn the 9's facts especially if you are visual person.  I'll let this little YouTube Video show you how it is done!  This one is even put to a song!


I hope these tips help make learning to multiply the dreaded 9's easy for your students!  If you have another tip for teaching 9's share it in the comments.  I'd love to hear what you do!

Thanks for hoppin' by Hopkins' Hoppin' Happenings.  Keep on smiling!
