### Math Secrets! (And an Anchor Chart!)

Have you ever shown something to your kids and it just blew their minds?!

That's what happened yesterday in my class during Math.

I showed my kids the trick for doing your 9's multiplication facts on your hands.  I started out by drawing the hands on the board.  Then I wrote the multiplication problem underneath.  Next I erased the finger we were using in the problem.  Then I showed them the fingers that were left actually revealed the answer to the multiplication problem!

They were AMAZED!  Immediately the kids started clapping and saying, "Thank you, Mrs. Richliew!!!"  I swear, it was one of the best moments I've had during my nine years of teaching!

Here's the anchor chart I made afterward.
Have you showed this trick to your kids?  How did they react?!

1. My kids LOVE the nines trick. Part of their homework tonight was to go home and teach their parents!

1. That's a great idea! I'll tell them that tomorrow. :) I came home and showed the hubby...too funny! He had never heard of it.

2. Love this! Too funny- I was going to teach my kids this tomorrow so they have something fun to practice over their Thanksgiving Break next week- great minds think alike :) Fabulous anchor chart!!

1. Haha! That IS funny! :) Hope they get a kick out of the trick!

3. I love the anchor chart with picture. I always have a hard time holding my hands to show them and having them practice with me. I end up having to turn around and hold my hands up. Then when I try to show them how to count, both my hands are being used so I can't point!!! hahahaha The chart makes it easier to visualize and try.

1. Thanks, Helene! That was my issue too! :)

4. My daughter learned a different trick. If it's 9x4.. she subtracted 1 from the 4 making it 3 - and then knew 3+6 = 9.. so 36..

It's pretty cool

5. omg...I have this planned for Monday! I found a youTube video on this if you're interested. I love your anchor chart though. I took a screen shot to add to my lesson....thank you for sharing!
