Terrific Triangles is a math facts drill-and-practice program that teaches fact families for both addition/subtraction and multiplication/division, with two playing modes.
There is a Student mode which allows individual facts practice with a running score for correct answers.The player may select difficulty and whether to play against a timer.
You may also select the Teacher mode that allows for group play. Students are presented with a problem and the timer spins one revolution. Then a student name appears and the timer spins again. The student whose name is shown tries to call out the answer before the timer finishes.
