Practice solving quadratic equations using the quadratic formula. This MATHO game is played like BINGO. Students solve a quadratic equation using the quadratic formula and then mark their answers on their MATHO card. Problems contain a variety of problems with discriminants that are positive, negative, and zero. Common Core Standard: HSA.REI.B4 Check out my other resources for more MATHO game options!

Students solve radical equations as they play a MATHO game. Each problem is a square root equation to solve. Some equations need to be rearranged and all are equal to a constant. As pupils solve the equations they mark their MATHO card with the solution. They get immediate feedback as they find the correct answer on their card. Common Core Standard: HSA.REI.A2 Check out my other resources for different MATHO game variations.

Make a game out of factoring! The resource provides 25 quadratic expressions to factor with a set of 30 MATHO cards. Students work out the problems and play BINGO with the answers. All problems have 'a' values greater than one. Problems are designed to give a variation of different sign patterns. Common Core Standard: HSA.REI.B4

Use this MATHO game to motivate your classes to practice their factoring! The resource includes a set of 25 quadratic expressions to factor, each with an 'a' value of one. Common Core Standard: HAS.REI.B4 See my other resources for more MATHO game options!
