### Multiplication Disks

First of all... I don't know how you all teach and have a blog!  This is the first post I've had since September and I had to share these cool multiplication disks.
My students needed to practice their multiplication facts so I told them I would make them flash cards.  However, to make flash cards for multiplication and division facts 1 through 12 for 17 children... well that's a lot of paper.  So I found these disks and they took far less time, and are so much cooler.  My kiddo's loved them!

﻿﻿﻿﻿
﻿﻿﻿﻿﻿﻿﻿﻿So here is how to make them:
SIDE ONE
1. Cut out a circle.
2. Put 12 holes around the edge - I used a cool star punch.
3. Put x ___ (the factor i.e. 1,2,3,4 etc...) in the middle.
4. Next to each hole write the numbers 1- 12 (I wrote mine random - because I wanted my students to practice them - you could also write them in order)

SIDE TWO
1. Write  ÷ __ (same factor as above)
2. Put your finger over the hole and figure out the problem from the other side. For example: If your factor in the middle is 6 and the hole you put your finger over is 7 (from the multiplication side) do 6 x 7.  This equals 42 so write 42 on the hole.  Do this for each number.
Here is an example of step two from above: 6 x 10

﻿﻿is equal to 60.  When I flip the disk over and look at the number where my finger was it should show 60

This is such a cool tool to use in the classroom... but so hard to explain... let me know if I need to upload a video and I'll see what I can do.

1. I am so excited that I found your blog. I am a first year 5th grade resource/inclusion teacher and I love your ideas! Thanks!

2. That is a great idea! I love the way they student can self-correct.

3. Awesome beyond awesome. This will help my son so much! I bet I could do this with addition.

4. wow..... can u upload a video?

5. Jennioutloud - the place where I saw it also had addition and subtraction ones too! This was so much easier than making flash cards.
Amhra - I will try... but as you can see by my posts... I'm not very good at updating... life is pretty busy with teaching and grad school right now.

6. I think I will have to do this at home with my 3rd grader!!

7. I love this idea. What type of paper did you use?

8. I'm curious to know how do you get a blog started? Thanks for this idea!!

9. FANTASTIC IDEA!!! After cutting 60 file folders and sitting down to Cricut-cut 240 circles to make a classroom set of these awesome flash cards, I realized that paper plates would work amazingly well for these! It may be a little costly to buy 300 paper plates, but not nearly as much as index cards would cost. THANKS for the idea!

10. Fantastic idea!!! :)
