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:
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)
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.
