Pentomino Frog Puzzle

Bring some rainforest fun to your classroom with this pentomino frog puzzle. Can you use a standard set of twelve pentominoes to build the shape of a frog?

I was inspired to type up this pentomino frog puzzle after a blog reader reached out asking me if I had any puzzles she could use for a rainforest themed activity at school.

Frogs came to mind, so I decided to see if anyone had figured out how to make a frog out of pentominoes. A quick google image search revealed a frog pattern that I was able to create a printable template for.

I tried out the frog pentomino puzzle with my high school students during the last week or so of school, and it was a big hit!

Whether your students are obsessed with pentominoes puzzles like mine or if you are looking for a fun rainforest activity, I hope other teachers will be able to use this puzzle in their own classrooms.

Puzzle Instructions

The goal of this pentominoes frog puzzle is to construct the shape of a frog using a standard set of twelve pentominoes. The pentominoes may be flipped or rotated, but they are not allowed to overlap one another.

Printing and Prepping the Pentominoes Puzzles

11 x 17 Version

This frog pentominoes puzzle is designed to print on 11 x 17 inch paper. I print all of my pentominoes puzzles on 11 x 17 cardstock for extra durability, but regular 11 x 17 copy paper will work just fine as well. (If you don’t have the ability to print on 11 x 17 paper, keep reading for an alternative printing option!)

All of my pentominoes puzzles are sized for plastic pentominoes made up of 1-inch squares.

If you don’t have a class set of plastic pentominoes, I do have a printable version of 1-inch pentominoes available to download and print. Please be aware that you MUST allow students to turn over the printed pentominoes pieces in order to solve the puzzle! This is less obvious than with the plastic pentominoes pieces.

Letter Sized Version

Since many teachers have told me that they do not have access to a copy machine or printer which prints on 11 x 17 paper, I have also uploaded a letter-sized version below which prints on 8.5 x 11 inch paper. You will have to trim and tape or glue the two letter-sized pages together to form the pentominoes puzzle board.

Hints for Solving the Pentominoes Frog Puzzle

Pentominoes puzzles which use an entire set of twelve standard pentominoes can be quite tricky to solve. When I shared the Pentominoes Heart Puzzle for Valentine’s Day, I heard back from numerous teachers that they had students work on the puzzle for over 45 minutes without finding a solution.

While some students can handle this level of perseverance, other students might benefit from a few hints in solving the puzzle. I have created a set of 4 printable hint cards that can be used with students to give them (or yourself!) a small piece of the solution.

These frog hint cards can be downloaded at the end of this blog post.

There are several ways you can use these printable hint cards in your classroom.

If you are having students work on the puzzle as a full-class activity, you can make the pentomino puzzle hint cards available after students have worked for a certain amount of time.

If you are using the pentominoes puzzles as an early finisher activity or as a puzzle of the week for students to work on in their spare time, you could post the puzzle without any hints on day 1. On each subsequent day, you could add a different hint card.

I look forward to seeing what other ways that teachers come up with to make these hint cards work for their students.

Ideas for Using in Class

I put up this frog puzzle as my puzzle of the week for students to work on if they chose to. Some students grab the puzzle and take it to their tables when they enter the classroom so they have something to work on while waiting for the bell to ring.

Other students will grab one of the puzzles to solve after completing their assignment for the day.

I hung two copies of the puzzle printed on 11 x 17 cardstock on my dry erase board with two sets of plastic pentominoes for students to grab in a magnetic pocket.

I love these magnetic pockets from Charles Leonard (available from Amazon) because students can easily grab the entire pocket of pentominoes and the puzzle and take it back to their desk to solve the puzzle.

This keeps me from having to pass out pentominoes or from students dropping pieces on their way to their desks.
