    I'm trying to come up with a real world applicable warm-up problem with adding fractions. Should I focus on the white board for the warm-up or an activity not centrally focused on the whiteboard in this case?

    I'm not a whiteboad kind of teacher.

    But FOOD is the all-purpose fraction topic!!!!

    All the cookies in the box have crumbled! You have one half cookie, and another third of a cookie. How many cookies do you have???

    I like the whiteboard better than a chalkboard. But if I get access to other technology and learn it and have time to create all these things that work with that technology such as a Promethean board, I think I would be happy to meld with it.

    Thank you for the help with such a simple problem that I could not think of!

    No problem. After all these years in the classroom, that stuff now comes pretty easily.

    How funny... I'm not crazy about white boards. I teach one, sometimes two,periods a day in rooms that have one. I always end up going through 5 or 6 pens before I find one that works well. At least with chalk, I know when I'm out.

    I have markers ALL over my tray--but usually end up carrying one I know works around in my pocket!

    That said, when I student taught we had a chalkboard--the dust drove me crazy.

    I don't even notice the dust anymore. I figure it's an occupational hazard.

    The other day, I got so frustrated trying one marker after another (and having my instructions written in 3 different colours), that I used the dried up markers to shoot "3-pointers" into the garbage can--I made all 4 attempts--then went to my office next door to get a new package!

    I'm completely with AliceACC....tie it in with FOOD! The kids seem to learn things with real life examples, and food works really well with the idea of fractions. I would try a pizza or a pie. If you don't want to do something unhealthy, there is always fruit pizza or veggie pizza. They are super yummy and very fraction-able!!

    The Warm-up caught their attention and I think the interest was maximized. Thank you!

    Split the class into groups of 5. Give each group a cardboard pie split into 4 parts. Have them figure out how to give an equal serving to each group member.

    Vary the number of servings and group size as you see fit.
