Pentasquares Puzzle

I’m really excited about this Pentasquares puzzle from Serhiy Grabarchuk. Pentasquares are five square shapes which fit inside a 3 x 3 dimension.
The goal of this puzzle is to put all six pentasquares inside a 6 x 6 square. You can rotate the pentasquares, but you may not overlap them or flip them over.
They will not form a perfect square,since 6 pentasquares X 5 squares = 30/36 possible squares. Instead, the goal is just to fit them within the square. There are multiple solutions.
To make it really clear which side of the pentasquares should be facing up, I added a dotted pattern to the front.
This puzzle is easy enough to leave out on a puzzle table for students to tackle on their own during spare class time. If you wanted to make it more of a full math lesson, I would have students discover the pentasquares for themselves first.
What is a pentasquare? Now, that you know what a pentasquare is, how many pentasquares are they?
As I said earlier, this pentasquares puzzle is by Serhiy Grabarchuk. I learned about it in Puzzle Box, Volume 2. This is one of a three-volume puzzle book set that is one of my go-to sources for excellent puzzles to use in the math classroom.

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 sarah@mathequalslove.net with information about what you teach and where you teach. I will be happy to forward an answer key to you.
Not a teacher? Go ahead and send me an email as well. Just let me know what you are using the puzzles for. I am continually in awe of how many people are using these puzzles with scouting groups, with senior adults battling dementia, as fun activities in their workplace, or as a birthday party escape room.

Love this activity. We “created”? (I’m sure I got many of the ideas from somewhere else) a similar activity for our 9th graders last year (fall 2019)…we didn’t do it this year, but now I’m wondering if we should break it out for the last day.

Awesome! I always love seeing the different ways teachers use pentominoes! Thanks for sharing!
Sarah thank you for all of the wonderful things that you pass on. We usually played the pentominoes game on a board 12 *12 with two sets (different colors).Each pupil had one set and in turn, put them on the board. The player who can’t put any more of his 12 pieces on the board loses.

I like this! I’ve always wanted a Blokus game for my classroom. This is like that, but faster. Plus, there are so many other things you can do with pentominoes! Thanks for sharing!
