Systems of
Equations
TIC-TAC-TOE
with
QR CODES
In this Tic Tac Toe, students will practice solving systems of equations.
In this puzzle, students practice solving systems of equations.
Students can work with a partner while playing this game. The first
student chooses to be X or O. They then choose a problem on the board.
They work that problem and then check their answer using the QR Code
provided. If they get the problem correct, they win the square. If they get
the problem wrong, the other student wins the square. Play continues,
back and forth, until one student gets 3 in a row. [CAUTION: Students
need to take care that they are scanning the correct QR Code as they play.]
Answer key for the teacher is provided.
I have also provided X’s and O’s that may be printed out and laminated for
students to use.
Great for a math center.
