In my Teaching Elementary math class today (to bad I am going to change my major to graphic design), we made an abacus!!!
We are learning how to do and teach bases other than ten. You know how you learn this stuff in like 3rd grade and never use it again?? We'll you use it again if you are going to teach third grade! heeheh...it was so fun to make...an its worth some fun!!
you'll have to click on the pics to get them full size...whoops!
Now, glue one set of 2 under the abacus in between the yellow and blue beads, and another set at the end of the abacus underneath the skewers. Glue the last 2 sets of 2 on top of the skewers between the yellow and blue beads and on the top of the skewers at the end of the abacus
It should look like this
