Painter’s Tape Strikes Again…

In all honesty my goal was to really use painter’s tape on the floor to make polygons in the first place, but I took a detour with painters tape on this geometry.  I just love the fact that floor tiles are actually a square foot– so with that in mind,  I had to stick a little area and perimeter lesson down on the floor.

Where did I stick the shapes?

You guessed it!  Near the bathroom of course!  After all, what other location in the entire school gets more visibility than the bathroom!

For the triangle and octagon I wrote inch measurements on the diagonal lines to help the students calculate the perimeter without a measurement tool.  You can’t see that in the pictures.

I numbered the shapes so that they could be matched to an answer key.  I was trying to leave in a hurry so I didn’t quite get finished with the answer key.  That will be coming soon.

Now, I did think to ask one of the evening custodians if this would be a problem, but she didn’t think so.  Well, the next morning, I got a “hmmmph!”  The day custodian immediately let me know that the tape had already come off of the floor a bit and asked me how long it would be there.

I said, “not long,” with a smirk.

He informed me that we had gotten second place for the cleanest school last year and showed me his plaque.

I said, “Well, we’ll be the most mathematical school.”

I’m leaving the tape down for a good 4 weeks ;D.
