This self checking worksheet starts with the standard form of the equation (which is in the middle of the page). The student will complete the square to find the Vertex Form of the equation (which is on the left side of the page). Then, match the Vertex Form of the quadratic equation with the Standard form to the Vertex (which is on the right side of the page). The student will keep track of the number and letter which match up with the same Standard Form equation. The student will fill in the riddle at the bottom of the page to solve a brain teaser.
