I shared this challenging communication activity with my FUNdoing Fridays followers in May of 2016 (Join the FUN by filling out any one of my "Sign Me Up" forms at any page here at FUNdoing and receive a handful of team building activities and ideas every Friday  FREE to you.)
My hope with this new activity (at the time) was to gather feedback about how it "works" to bring out useful communication skills and problem solving behaviors. I didn't hear from anyone. So I ended up sharing my set of Number Squares (and the directions) with a few friends to let them try it out. They told me the preparation information for the activity was not very clear. Let me fix that. I'm using some space here to share more about the set up of the number cards in the hopes of eliminating one of the main barriers to using this activity.
Below (in PDF form) you will find the full detailed write up I have for Number Squares and the printnplay number cards. There are three different challenge levels for this one. There is a 16card version that I consider to be the easiest. There is a 25card version with a "hollow" numbered center card  a moderate difficulty level. Then, there is a 25card version with a "solid" numbered center card which I consider to be the most difficult version. (All three puzzle layouts are below.) BONUS VARIATION: A friend of mine suggested that you can also play any of the three variations where players can show  but not give away  their card(s) to others. As a nice progression, I intend to try the 16card puzzle first giving my group the option to show others their card(s) and then play the 25card puzzle where they can only describe what they are holding. This might make the 25card puzzle a bit easier to solve once the group learns about the number cards for their first attempt.
Playing the Game: In a nutshell, each player has one or two number cards and can only verbally share what is on his/her card(s) to other players (this is a ZOOMstyle activity, if you know that one). In the end the group places the cards down on a table (or floor) in the correct 4by4 or 5by5 pattern. (Again, there is a fullydetailed PDF of the activity below.)
Included in the set of number cards are the answer cards for each of the two puzzles  the 16card puzzle and the 25card puzzles.
Each number card in this activity has a letter designation (see the cards below). The letters are used to identify each card in relation to the answer of each puzzle. This letter designation also helps when pulling out the number cards you want to use with a group. Again, there is one 16card puzzle (easiest), and two 25card puzzles  one with a hollow numbered center card (card C) being the moderate challenge, and a solid numbered center card (the other card C) being the most challenging variation of the three.
Here is the part that can be confusing:
There are two of the following cards: X, H, W, A, G, E, I  one set for the 16card puzzle and one set for the 25card puzzle. Look at the puzzle solutions below. Notice that the numbers on the outside edges of each puzzle are comprised with "hollow" numbers  this designation is a fact that groups will (hopefully) come to realize after communicating with clear details. This fact can help groups piece the puzzles together. When you use the 25card puzzle you need to replace the right and bottom edge cards of the 16card puzzle with the other set of numbered X, H, W, A, G, E, I cards. Then add the D, Q, Y, N, V, F, K, R & O cards for the right and bottom edges.

25Card Solution (with solid numbered center card)
I hope this information is helpful. First and foremost, you need to decide which puzzle set of cards you're going to use. Then, pick them out of your set  put any extras out of sight. Be sure you have the appropriate answer card for the puzzle you are using and have some, or all, of the Help Cards available as resources for your group. (Help Cards are described in the full write up of directions below.)
Okay, please let me know how Number Squares plays for you. Any feedback is welcome!
All the best,
