Tic Tac Toe


Tic Tac Toe is a fun maths game

Maths games that support students number sense development are popular in Room 3. Tic Tac Toe  is based on the traditional tic tac toe or connect 4 game.


Jack has made three in a row can he get four

Tic Tac Toe is a partner game. You need a blank 100’s square and two different colour pens. Each player is trying to make a vertical, horizontal or diagonal line of 4 consecutive numbers while stopping their partner from doing the same. The challenge level can easily be changed by requiring students to achieve 3 or 5 numbers in a row. 


Total concentration from Ryker and Jake

This game supports students' development of number sense . In particular, their understanding and fluency of number order and patterns.  Place value knowledge is also secured as students identify numbers vertically and diagonally on the 100’s board.  This game can easily be extended to have students work with bigger numbers by for example making the 100’s square from 300- 400.  It is easy to have several games on the one number square and keep a tally of the results.

Buddy Class Teaching

After Room 3 became confident playing Tic Tac Toe, their next challenge was to teach the game to their buddy class Room 2.

We had an odd number so Alyssa took on the challenge of teaching two Room 2 students

Tic tac toe is a fun game because it is like noughts and crosses and I really like noughts and crosses.  It's kind of a game of strategy. Louie Room 2

I like tic tac toe because you can block your partner and you can get a lot of points.  I taught Aiden how to play it.  Ryker Room 3

I taught Dorian how to play. It was a real even match because neither of us got any points.  Finn Room 3

I taught Billy how to play and it went pretty well.  I think we actually need three different colour pens. We need another colour to put the 1, 10, 91 and 100 in the corners.   Sam Room 3

I like how sometimes you can make a pattern if someone is trying to block you.  Avery Room 3

To be good at tic tac toe you have to know where you are going and you have to know your numbers.  Molly Room 3

I liked going into Room 3 to learn to play Tic Tac Toe.  Zoey taught me how to play.  Sadie Room 2

It was a little bit hard working out where the numbers go.  Sky Room 2

Next Steps


You can almost see the steam rising our of these brains


This looks like an intense game

Students who are confident with numbers to 100 could take on the challenge of playing the game with bigger numbers. Another next step could be to learn another game to share with our buddy class.

Mrs Sprague’s next step is to learn to back off and let students teach each other - I may have taken over a little bit. Room 3 could teach the other classes in our team the game and Mrs Sprague could learn to zip her lips.
