Multiplication facts to 12

What you'll learn

• Identify the direction (upward or downward) a parabola opens based on the sign of the leading coefficient 'a' in the quadratic equation f(x) = ax² + bx + c, with 100% accuracy on a formative assessment.
• Determine whether a parabola opens left/right, up/down based on the form of a quadratic equation (y = ax^2 + bx + c or x = ay^2 + by + c) and the sign of 'a' with at least 80% accuracy on a graded worksheet.
• Explain the relationship between the sign of the leading coefficient 'a' and the direction of the parabola's opening in a written explanation using proper mathematical vocabulary, as assessed by a rubric focusing on clarity and accuracy.
• Given a set of 5 quadratic equations in standard form (f(x) = ax² + bx + c or x = ay² + by + c), accurately classify each equation as opening upward, downward, left, or right with 100% accuracy.
