A Plus Puzzle

Engage students with the A Plus Puzzle! Free printable math activity where they assemble 5 pieces to form a plus sign. Fun and interactive for all!

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 Plus Puzzle from The World’s Biggest Book of Brainteasers & Logic Puzzles. 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 A plus 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.

Puzzle Solutions

I intentionally do not make answers to the printable math puzzles I share on my blog available online because I strive to provide learning experiences for my students that are non-google-able. I would like other teachers to be able to use these puzzles in their classrooms as well without the solutions being easily found on the Internet.

However, I do recognize that us teachers are busy people and sometimes need to quickly reference an answer key to see if a student has solved a puzzle correctly or to see if they have interpreted the instructions properly.

If you are a teacher who is using these puzzles in your classroom, please send me an email at with information about what you teach and where you teach. I will be happy to forward an answer key to you.

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.

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?
