A+ Puzzle

Mondays are quickly becoming a day that my students look forward to. Yesterday, I overheard one student excitedly tell another that they were excited to see what this week's joke was. Then, they raced to read it and check out the answer.

Ready for it? According to another one of my students, this week's joke is a good one!

Monday is also the day of the week when I switch out our weekly magnetic puzzle.

Last week, we tackled the Nine Squares Puzzle that I posted this summer.

This week we're testing out a brand new puzzle called the A+ Puzzle from The World's Biggest Book of Brainteasers & Logic Puzzles (affiliate link). This book is massive at around 700 pages, but I was a bit disappointed in the fact that it had very few puzzles of the sort that I like to use in my classroom with moving pieces.

The puzzle gives you five shapes which must be arranged into a plus sign. Yes, it is possible.

No, this does not count as a plus sign. 

Yes, this will drive both students and teachers crazy. I included this in a presentation I did this summer, and I had some teachers rather frustrated with this puzzle for quite some time. The look on their faces when they finally figured it out was priceless.

  1. My students want to know if the pieces can be stacked?

  2. Can you please post a solution??!! Four adults 120 kids couldn't figure it out today! LOL . My kiddos are really wanting to know the answer to this.


  3. Changing the puzzle weekly is a great engagement tool and way to keep the students looking forward to doing math which can be a difficult subject for some. Do you just browse amazon to find your resources or are there any blogs/sites you follow that recommend materials?

  4. Can you post the solution?

  5. I used to do fun things like puzzles of the week. Thanks for the ideas and the reminders! It seems like I never have time to do anything extra. But I would like to implement some things for students to look forward to.

  6. solution includes the biggest piece being diaganal
