Make It Fifty-Fifty Encephalon Teaser

Last Friday, I pulled a new-to-me encephalon teaser out for Figure It Out! Friday.


I constitute a puzzle called "Make It Even" inwards The Moscow Puzzles: 359 Mathematical Recreations yesteryear Boris A. Kordemsky.


The mass is published yesteryear Dover, then it's super affordable at $3.99!  I've constitute numerous puzzles I desire to seek out amongst my students.  This is the 2nd calendar week inwards a row that our figure it out puzzle has come upward from this book!

The master puzzle called for xvi objects.  I decided to role bingo chips since I convey a giant bag.


To relieve fourth dimension as well as non convey to purse upward xvi bingo chips per student, I took a packet of v plastic bowls I bought at Dollar Tree for $1 as well as divided the bingo chips into these bowls.  The bowls are inexpensive feeling, but at $0.20/piece they are amazing!


Here they are, stacked as well as cook to go.


My Algebra 2 students as well as Stats students were much improve at reading the instructions as well as attempting the puzzle on their own.


My Algebra 1 students struggled fifty-fifty when I read the instructions to them.

There were a ton of "This is likewise hard" or "This is impossible" comments.  In each class, at to the lowest degree 1 pupil figured it out though!

I can't country you lot how many times a pupil would heighten their mitt to convey me banking concern tally their solution, as well as I would walk over to discovery that they had a column or row amongst 1 inwards it.  I intend they were only likewise focused on making the rows fifty-fifty or making the columns fifty-fifty to fifty-fifty expect at it the other way.

Part of me at 1 time wonders if students would perform differently on this occupation if it was presented differently.  Maybe similar this?


Some of my students tried rearranging the 10 leftover chips into 2 rows of 5.  I intend this 2nd phrasing of the employment would forestall that.  If I did the 2nd version, I'd definitely plough over it to my kids within a dry erase sleeve.

Or, perchance combine the 2 methods as well as plough over students the grid as well as exclusively 10 chips?
