How do you use cuisinairre(sp) rods to teach fractions? Would you be able to teach adding and subtracting fractions with them?
Thanks

you could definitely show "parts of the whole" fractions by using a 10 rod, for example, and doing 1/2s and 1/5s, or a 6 rod and show 1/3s, and 1/2s, etc...

I'm so glad you asked about the adding/subtracting fractions aspect, though...I can't seem to wrap my head around how to teach it with number rods, though I'm sure you can and it's probably really cool!

We use Miquon and Cuisenaire rods... but when it came to fractions, I printed out the pieces and circles from here. I printed it on cardstock and used a different color for the different fractions. (Orange for thirds, yellow for halves, etc.)

I could understand how to use the rods - but the kids just didn't get it at all, having been "trained" that a little red one =2, not 1/3... KWIM?
