Scaffold practice of the quadratic formula and two find the error problems.
The first four problems all have part of the quadratic formula set up and solved correctly and ask the students to finish the process of solving for the zeros using the quadratic formula. Each problem has less of the problem solved for the student so they are able to build their confidence to solving an entire problem. The next 6 problems are a quadratic equation where students must find the zeros using the quadratic formula. Lastly, the last two problems are completely solved, but they are solved incorrectly. Students must find the error and fix the error to find the correct zeros of the quadratic function.
