Today I’m excited to share the 9 Dots Puzzle with you. I love puzzles. I also love finding a way to incorporate them into class.

Since the first week of school is rampant with schedule changes (especially this year since we don’t have a guidance counselor), I aim to engage my students in math-y activities that get their minds working but don’t necessarily tie into the curriculum.

I’ve decided to do daily warm-ups this year that students will keep in their interactive notebooks. School started on Monday, and we won’t be setting up our notebooks until tomorrow (Thursday). This means that my students needed a place to keep their warm-ups until notebooks were set up.

Introducing the Warm-Up Divider!

At first, I wasn’t sure what to put on this divider. Then, I realized I could put warm-ups ON the warm-up divider. Can’t believe it took me so long to think of that!

I did this for both my Algebra 1 classes and my Chemistry class. The divider pictured above is for Chemistry.

On Tuesday, I assigned them one of my favorite brain teasers: the nine dots puzzle.

Without lifting your pencil (or dry erase marker), draw four straight lines that pass through all nine of the points.

Since this one is a bit tricky, I decided to make them a dry erase template that would give them lots and lots of chances to try and solve the puzzle.

I figured if they had to draw and erase too many times that they would just give up.

Here’s what I came up with:

When I gave my chemistry students the option to use the dry erase template yesterday, almost every kid chose to use it!

I think only one student went without, but he came in late anyway. I’m assuming he just ended up copying off of the person sitting next to him…

Each table’s folder had templates inside. Kids just had to slide the template of the 9 dots puzzle into one of our dry erase pockets.

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.

The kids really struggled with the 9 dots puzzle, so the dry erase template really paid off!

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.
