Are you ready to take on the Sixes Challenge? You must use exactly four sixes and your choice of arithmetical symbols to form the eight given target numbers.

This puzzle is just one of many free printable number challenges that I have created for my own classroom and am sharing with you!

What is the Sixes Challenge?
Using exactly four sixes, add arithmetical symbols between the sixes to make each of the target numbers. You may use plus, minus, times, and divide symbols, as well as parentheses and brackets for grouping.
This sixes challenge is a fun twist on the classic Four Fours Puzzle.
Source of Challenge
I discovered this challenge based on the number three in Pierre Berloquin’s 100 Numerical Games book.
I picked up a copy of the book several years ago at Goodwill, and it has inspired numerous classroom activities over the years. Previously, I have blogged about the 20 x 9 Challenge, the Twos Challenge, the Threes Challenge, the Fours Challenge, and the Fives Challenge.
Ideas for Using in Class
I have previously used this challenge with students on the first day of school as part of the Twos to Nines Challenge. I put challenges up for each of the numbers from two to nine around the classroom for students to tackle on our dry erase boards.
I created a printable PDF template for the sixes challenge that already has the four sixes written in. Students just have to add various mathematical symbols to make each expression mathematically correct.
For puzzles like this, I usually only print a class set of copies in order to save paper. I prefer to give my students these puzzles in a dry erase pocket. You can pick them at places like Dollar Tree and Target’s Dollar Spot, but I’ve found they are much cheaper when you buy a classroom set from somewhere like Amazon.
MATH = LOVE RECOMMENDS…
I cannot imagine teaching math without my dry erase pockets! They instantly make any activity more engaging and save me countless hours at the copy machine since I can use the same class sets of copies year after year.
Here are my current go-to recommendations:
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.

Puzzle Solutions
Puzzle solutions are available on a password-protected solution page. I do not openly post the puzzle answer keys because one of my goals as a resource creator is to craft learning experiences for students that are non-google-able. I want teachers to be able to use these puzzles in their classrooms without the solutions being found easily on the Internet.
Please email me at sarah@mathequalslove.net for the password to the answer key database featuring all of my printable puzzles and math worksheets. I frequently have students emailing me for the answer key, so please specify in your email what school you teach at and what subjects you teach. If you do not provide these details, I will not be able to send you the password.
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, or as fun activities in their workplace. Just give me enough details so I know you are not a student looking for answers to the puzzle that was assigned as their homework!
