I remember I saw a demonstration on teaching a particular topic, and they used these things called "something" sticks. I'm trying to figure out what "something" is so I can purchase these. They are small, flexible (not plastic, not pipecleaners), maybe a few inches in length, multiple colors of them exist, almost like clay, but not. I know this is vague, but she called them _______________ sticks. I think it started with or had a q in the name, but I can't remember. I think they would be great for introducing trig. Anyone have any idea what I'm talking about? You'll be my best friend!
