ACHI Math Game - Achi is a game played by the Asante people of Ghana that is similar to tic-tac-toe, but tic-tac-toe ends when all the pieces have been placed; instead, Achi continues. Let's play!

This is an ongoing program.

Thank you to MathTalk for bringing this activity to us!

Your Math Challenge: Can you get your three counters in a row? Play against a friend and see if you can reason and strategize by thinking ahead to win this game! 

Directions: This game is played like tic-tac-toe. Each player has four counters.
(If you don't have any game counters are home, you can use four pennies and four nickels as counters.)

1. Taking turns, each player places one counter on a circle

2. If three counters on one color are in a row, that player calls out “Achi!" and wins the round.

3. If both players have played all of their pieces and no one has won, then players take turns sliding a counter on a line to the empty circle.

4. When a player makes a line of three of his/ her counters by sliding, that player calls out “Achi!” and wins the round.

This activity supports the practice of these STEAM Habits of Mind: Develop craft, engage & persist, observe, reflect, stretch & explore.

Tips for Supporting Your Children's Learning

Get your child actively involved in their own learning and having their questions drive the learning. Let them observe and figure out, and try to hold back from answering questions for them. Instead, try to ask: What do we know? What else can we find out? How might we figure that out? Don't be afraid to ask your child questions.  Also, don't be afraid to say "I don't know--let's find out together!" as a way to respond to their questions.  Here's an article to help you support this kind of learning:  Of the Value of Saying I Don’t Know
