Here are a few shots of me using my 100 bead strings.
For someone who has only been blogging for a few months... you can see that these get used over and over again. The pictures above were taken in grades 2-5 so there is a wide range of times where these are used. I also use them in K and 1 for counting and grouping activities and thinking about adding and subtracting multi-digit numbers.

Materials Needed (To make 20 Bead Strings)
All prices given are for what I paid on Amazon
All prices given are for what I paid on Amazon
Red Pony Beads (1000 beads per package) $5.14
White Pony Beads (1000 beads per package) $6.13Colored Cords (42 yards) $5.10. You will only use about half of this and have the rest left over for another project or to share with another teacher!
Grand total $16.37 which is about 82 cents per bead string. The shipping was free when I spent $25 which meant I ended up ordering a few other things while I was on Amazon.
How to make
- Cut colored cord into sections about 1 yard long. Fold over a few inches and tie off one end. I like to leave a loop on the end so that I can hang them up when I am not using them.
- Once the ends are tied off, I like to have pairs of students make these. Working together, they alternate 10 reds with 10 white beads until they get to 100. Once there, I have them re-count to check and/or I have them put their bead string up against one I already have made to see if their sections match up with mine.
- Once we have checked the bead string, it is time to tie off the other end. Older students can sometimes do this themselves but I often end up tying off all of them myself in younger grades.
Now your bead strings are ready to use! The possibilities are endless:)
How do you or would you use a 100 bead string in your classroom?
Very intriguing! I haven't seen these before. I'd love to see a post on how you use them with k to 2.
