A while ago I was introduced to Skyscraper Puzzles (I believe they were invented by BrainBashers). I’ll explain below about the specifics of how to play, but basically they are a great way to help our students think about perspective while thinking strategically through each puzzle. Plus, since they require us to consider a variety of vantage points of a small city block, the puzzles can be used to help our students develop their Spatial Reasoning!

I’ve written before about how to help your students persevere more in math class and I still think that one of the best ways to do this involves physically and visually thinking about tasks that involve Spatial Reasoning.

While I loved the idea of doing these puzzles the first time I saw them, I was less enthusiastic about having these puzzles as a paper-and-pencil or computer generated activity because it is difficult to help develop perspective without actually building the skyscrapers. So, I created several templates that can easily be printed, where standard link-cubes can be placed on the grid structures.

Below are the instructions for playing and templates you are welcome to use. Enjoy!

#### How to play a 4 by 4 Skyscraper Puzzle:

- Build towers in each of the squares provided sized 1 through 4 tall
- Each row has skyscrapers of different heights (1 through 4), no duplicate sizes
- Each column has skyscrapers of different heights (1 through 4), no duplicate sizes
- The rules on the outside (in grey) tell you how many skyscrapers you can see from that direction
- Taller skyscrapers block your view of shorter ones

Below is an overhead shot of a completed 4 by 4 city block. To help illustrate the different sizes, I’ve coloured each size of skyscraper a different colour. Notice that each row has exactly 1 of each size, and that each column has one of each size as well.

Below is the front view. You might notice that many of the skyscrapers are not visible from this vantage point. For instance, the left column has only 3 skyscrapers visible. We can see two in the second column, one in the third column, and two in the far right column.

Below is the view of the same city block if we looked at it from the left side. From left to right we can see 4, 1, 2, 2 skyscrapers.

Below is the view from the back of the block. From left to right you can see 1, 2, 3, 2 skyscrapers.

Below is the view from the right side of the block. From here we can see 2, 2, 4, 1 skyscrapers (taken from left to right).

When playing a beginner board you will be given the information around the outside of your city block. Each number represents the number of skyscrapers you could see if you were to look from that vantage point. For example, the one on the front view (at the bottom) would indicate that you could only see 1 skyscraper and so on… The white squares in the middle of the block have been sized so you can actually make the skyscrapers with standard link cubes.

#### A few thoughts about how you might use these:

- How will you introduce these puzzles to your students? How much information about strategies and tips will you provide? Will this allow for productive struggle, or will you attempt to remove as much of the struggle as possible?
- Would you use these as an activity you give all students, or something you provide to just some. Why?
- How would giving a puzzle to a pair of students be different than if you gave it to individuals? Which were you assuming to do here? What if you tried the other option?
- How might using physical blocks be different than paper-and-pencil or electronic versions?
- How will you orchestrate a conversation for your class to help consolidate the learning here?
- What will you do if students give up quickly? What questions / prompts will you provide?

A belief I have: Teaching mathematics is much more than providing neat things for our students, it involves countless decisions on our part about how to effectively make the best use of the problem / activity. Hopefully, this post has helped you consider your own decision making processes!

I’d love to hear how you and/or your students do!

This is the same thing that used to be on T!-73 calculators, but with a hands on approach. Glad to see it in a more concrete form.

My students loved using this! I teach 5th grade and most of them were very engaged. I gave minimal instructions. I turned your pictures into a simple power point and then let the kids work it through. After a few solved the beginner 4×4, I had them share their strategies. One of my squirreliest students had so much fun with these. He made all the sizes he would need first then started placing them on the board. Awesome!

Tanks for sharing Pam. I’ve heard several stories about how these puzzles have helped reach some of the hardest to reach, or the ones who struggle the most…

Nice to provide things that can help with confidence and help build spatial thinking at the same time!

Hi Pam, would you mind sharing your Power Point for this?

I can’t download the grids? Anyone have any ideas or another way to get them.

I love these! Just did the 4×4 with my kids.

Wanted to do the 5×5 easy, but the link isn’t highlighted and you can’t get to it.

Could you email it to me? ngolden@merrick.k12.ny.us

I’ve occasionally used these before but it’s great to have a decent set of problems to solve. It’s hard finding ways to develop spatial reasoning so this is really useful. Thanks!

how do you play the 5 x5, buildings with 1 to 5 blocks?

To play the 5 by 5 games. Same basic set rules apply. However, instead of there being for towers in each row and column there are now five towers in each. Yes, you are correct in that the towers are now sized 1234 and five for each row / column. If you would like, I could send you a picture of a finished puzzle. Just let me know where I can share the picture (your email or twitter account…).
