They try this problem, with their
fraction pieces and a timer

A slide and its progression.
From top to bottom:
the old style visual aid, wrapped in
rubber bands to hold it together; the same prism, now on the smart board, peeling off the layers,
breaking off the individual
cubes and displaying
the solution.

Then, reveal correct answer, and misconception. |
The screens I chose to show in the guest blog demonstrate the use of manipulatives in the classroom, which is considered a good practice, methods to dispel misconceptions, which is extremely difficult to do, and engaging, hand-on lessons, which, if you're a teacher, you know means headaches! I've developed these lessons for use with the smartboard, and there are hundreds of slides with cartoons, turn and talks, think pair shares, reflections, procedures, do nows and links to interactive websites. The instant access to visuals is a godsend for a teacher who is accustomed to having to draw such things as turnstiles and radiometers, to little effect. But even better are the interactive elements. The smartboard timers help keep students on task, and they even give me a better feel for how long three minutes really is. I no longer have to circle the classroom with a rectangular prism made of snap cubes in my hand, demonstrating what the dimensions of the prism are. I can spin spinners, flip coins, or toss dice without having to tell the students to "trust me, it's heads". I do not have to buy the incredibly expensive quad-ruled chart paper to teach the coordinate plane or graphing. And I don't have the aggravation of other teachers in my classroom blithely taking a sheet or two without permission and using them indiscriminately after I take such care to use them sparingly by plotting things in pencil and erasing it clean before the next class. That's over $2.00 a sheet, people! And, while I'm on the subject, do you have any idea how expensive overhead projector lightbulbs are? They're not cheap! Don't leave it on for the whole period, because the fan doesn't work and it's going to overheat! I'm not paid enough for these supplies!!!
Ahem, <straightening my tie>, where was I? I like the smartboard. For those of you who are interested, this is a tiny glimpse of my life as a teacher. For fellow teachers, if you'd like copies of my smartboard lessons, I'd be more than happy to share them. You don't even need a smartboard to use them, just a computer and a projector and a copy of the software. This is how I use it, because I no longer have a smartboard, either. I have most middle school math topics done, and a few 6th and 7th grade science lessons. Leave a comment and I'll send you them.
And if you're curious about the GCF and LCM, first off let me say that you're a bit strange, too. No, I'm kidding: intellectual curiosity is one of the great gifts of being a human. But follow this blog, and we just may cover it, like it or not!
