This 9 Pumpkins Puzzle is sure to provide your students a fun Halloween themed math challenge. Without lifting your pencil, draw 4 straight lines that pass through all nine of the pumpkins.
This is a Halloween-specific version of a classic brainteaser known as the 9 Dots Puzzle. The original puzzle is often attributed to Sam Loyd, but that fact is debatable.
Recently, a blog reader asked me if I had any Halloween math puzzles available to download. This question got me thinking about what puzzles I have used with my students in the past that could be modified for Halloween.
This is a classic example of a “think outside the box” brain teaser. As long as students are thinking “inside” the grid of the nine pumpkins, they will be unable to find a solution to the puzzle.
When I have used this puzzle with my students in the past, I like to give them the puzzle in a dry erase pocket. This lets them try multiple solution methods without having to do a lot of erasing on their paper or redrawing of the grid of nine dots/pumpkins.
If you don’t have a classroom set of dry erase pockets, you could also use heavy duty sheet protectors. But, I highly recommend investing in a classroom set of the pockets since they are so much more durable.
Free Download of 9 Pumpkins Puzzle
The downloadable file for the 9 Pumpkins Puzzle includes two versions. The first version assumes that students are solving the puzzle with a pencil. The second version assumes that students are solving the puzzle with a dry erase marker inside of a dry erase pocket.
I intentionally do not share solutions to the puzzles I feature on my website because I strive to provide learning experiences for my students that are not 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 email@example.com with information about what you teach and where you teach. I will be happy to forward an answer key to you.
