Hexaflexagon Love

All of the teachers inward my schoolhouse are supposed to practise semester tests on laid days.  Yesterday, nosotros did semester tests inward our odd-numbered hours.  Today, nosotros tested inward even-numbered hours.  Some of my students were a piddling confused past times the odd/even distinction.  They mistakenly sentiment the 24-hour interval yous tested on was determined whether at that spot was an strange or fifty-fifty publish of students enrolled inward the class.  Once nosotros got that cleared up, it went pretty smoothly.

The exclusively occupation I conduct keep amongst the whole organization is that I all the same conduct keep my strange periods for 3 to a greater extent than days together with my fifty-fifty periods for 2 to a greater extent than days earlier the semester ends.  It's non plenty fourth dimension to start a novel unit, only I'm non ane to allow my students practise nothing.  They know this well-nigh me.  I passed out evaluation sheets for my students to create amount out, together with a lot of students answered "more gratis time" to the inquiry "What changes practise yous desire to run across side past times side semester?"  That's definitely non going to happen. 

Today, my classes that were finished amongst their semester tests, filled out the evaluation forms together with explored the exciting basis of hexaflexagons.

Hexaflexagon Love.


We started past times watching this video past times Vi Hart.  If you've never seen a hexaflexagon before, yous conduct keep to spotter this video!  Trust me, yous volition survive amazed  



Then, I passed out blank trihexaflexagon templates from puzzles.com.  This website has ii versions available.  One template is larger together with includes exclusively the template.  The other template is smaller, only it likewise includes the assembly instructions.  I printed off the minute template for myself together with the first, larger template for my students.

Now, if I was a geometry teacher, I would definitely role the data available inward this tutorial to conduct keep my students role a ruler together with orbit to conduct keep students create their ain hexaflexagon templates.  How awesome of an introduction to geometric constructions would that be?!  

The directions on the minute template are well-written, only my students are non the best at next directions.  I establish it easier to present my students what to practise using the document photographic idiot box camera than having them endeavour to follow written instructions.

I did conduct keep my students publish their template equally shown inward the instructions.  This way, I could say my students just what numbers should survive showing at whatsoever indicate inward the structure process.  If a student's numbers did non fit mine, it was obvious, together with nosotros could run to laid the occupation immediately.

I learned later my showtime course of education to brand certain I told students to crease each crimp BOTH ways.  Otherwise, my students had a lot of problem making their hexaflexagons run since the creases were weak.

After cutting, folding, together with gluing, my students were eager to flex their hexaflexagons.  After many one-on-one lessons amongst students to present them where to pinch together with open, the room was abuzz amongst excitement.  Students used the residual of the course of education menstruum to coloring their hexaflexagons.

I did this lesson 3 times today.  Two classes loved it.  The other couldn't conduct keep cared less well-nigh hexaflexagons.  They didn't desire to coloring them or play amongst them or fifty-fifty brand them.  I conduct keep no sentiment why...
