# In a Row Puzzle

Post Contents

This In a Row Puzzle challenges students to arrange the digits 1 through 9 in such a way that four statements regarding the sum of various subsets of the row are true.

The numbers 1 and 2 and all the digits between them add up to 9. The numbers 2 and 3 and all the digits between them add up to 19. The numbers 3 and 4 and all the digits between them add up to 45.

Finally, the numbers 4 and 5 and all the digits between them add up to 18.

Often, people ask me where I run across the puzzles I use with my students and share on my blog. Hereâ€™s the short answer: One of my hobbies is reading through as many puzzle books as I can get my hands on.

I love checking puzzle books out of the Internet Archiveâ€™s free Online Lending Library for this purpose.

I discovered this puzzle in Maximize Your Brainpower: 1000 New Ways to Boost Your Mental Fitness by Philip Carter and Ken Russell. I checked this book out for free from the Internet Archiveâ€™s Online Lending Library that I mentioned earlier.

I attached disc magnets to the back of the digits 1 through 9 so that students can move them around as they work to solve the puzzle.

If you had students working in groups at their tables, you wouldnâ€™t need magnets at all. You could even give this as a task on whiteboards with no number cards at all.

## 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.
