My kids where so bored and I had to do something to make math more exciting. I was teaching a lesson on cuboids and I was losing them. Something big had to be done to get their attention.

I was feeling pretty proud for having all the supplies I needed. Some of the students enjoyed the math lessons. Their hands went up during question and answer time.

But the hand that I was looking for at the front corner of the class never went up. Justin (let’s call him Justin) just sat there looking away from me, tapping his ruler on the desk. Then he poked another student with his pencil.

Now, it is not uncommon for him to be like this because he sometimes gets into trouble in order to avoid class work. What I needed to do was to get his attention without halting the momentum that the other students were having. At that moment, an idea popped into my head

I walked out of the room, spun around and returned with a silly grin and a cuboid net in my hand. I didn’t say a word. I just slowly folded the net into a talking cuboid (like a puppet). Think of a box with the top lid open – that flap became the puppet’s mouth. Anyway, I used the silliest voice I could muster and made the puppet talk.

He introduced himself as Corey the Cuboid and went on to talk about his other siblings and the fact that he feels like the odd one out because he cannot roll like the cylinder or sphere and he’s not as cute as his brother the cube. My fourth grade students were wide eyed and everybody was paying attention – not to me the teacher, but to the cuboid on show.

They all wanted to have their turn with handling Corey the Cuboid and making him talk (including Justin). In fact, they had so much fun making him talk that I videotaped one of my students as she brought Corey to life!

I really enjoyed that cuboid net lesson and it taught me that even with a lot of planning, a touch of spontaneity keeps things interesting. The lesson gave me an idea for their math project – to have them put on their own puppet show featuring different talking 3D Shapes.
