I have a little girl who is
obsessed in love with the math manipulative counting bears. I mean OBSESSED in love with them. She wants to take them, have them, touch them, do everything with them.
One little trick I want to share with you is this: when you use a working card, rather than the traditional happy faces or stars, substitute those for a high motivator. For this girl, I pass out "bears" rather than happy faces. She get's SO excited when I say, "stay seated so I can give you another bear." While this does not work for every student, it occasionally works for that one special student!
Try it out with a kiddo :) and let me know how it goes!
