I use these as an interactive game for my class when we discuss the meaning of the equals sign. Great for whole group or small group.
To put these together, simply cut out and fold across dotted line around a popsicle stick (with glue to stick). Then you have your sign, one side is True and the other side is False.
Teacher presents numerous equations (e.g. 7-3=4 and 6+6=10) that may be true or false.
Students hold up their sign for True or False depending on the equation.
