New ReviewBy watching an informative video, young mathematicians learn how to write an equation from a table. In this case, the underlying equation is no longer linear, but rather it is quadratic.

New ReviewHere's the solution to your needs. A PowerPoint presentation from the Claim 1 Item Slide Show series gives 17 questions for scholars to complete. They must solve linear equations, linear inequalities, quadratic equations, and literal...

What's in a triangle? Just 180 degrees worth of angles! Young learners use given angle relationships in a triangle to write an algebraic representation. Using a system of equations, they simplify the equation to a linear representation.

Come full circle in learning about conic sections. Learners first look at the type of conic section formed when concentric circles intersect a standard coordinate plane. They then see which type forms when two sets of concentric circles...

Weight is a function of the distance from sea level. Learners explore the many implications of this fact in an inquiry-based task. Given the function, pupils answer questions before manipulating the function to rewrite the distance from...

There is power in spreadsheet formulas and learners use this power to model quadratic data. Given a scatterplot of a parabola, pupils create formulas in a spreadsheet to populate the data. The formulas they use lead to an understanding...

Sketch the graph of quadratic functions using key features as a guide. After a brief discussion about the key features of a parabola, the video instructor completes several examples showing how to graph a quadratic function. Each...

The structure of an expression is a descriptive feature. Learners build a solid understanding of quadratic functions using an analysis of expressions in different forms. The seventh module in a series of nine includes 12 lessons...

Use an understanding of equality to find solutions of quadratics graphically. A well-designed lesson illustrates the relationship between the right and left sides of an equation graphically. With one side quadratic and the other side...

One of the many methods of solving quadratic equations is graphing. A video lesson first demonstrates graphing a quadratic function using an input-output table. After graphing the parabola, the instructor makes the connection between the...

Formulas don't appear from thin air! Learn how to derive the quadratic formula by completing the square. As the video instructor demonstrates each step of the derivation, the quadratic formula begins to emerge until it is complete in the...

When all else fails, use the quadratic formula! A video lesson introduces the quadratic formula to scholars and then demonstrates two problems. One problem results in integer solutions, the other in irrational solutions.

Map the input to the output and see what pupils create. The video lesson provides an introduction to graphing quadratic functions using an input-output table. The instructor shows each step of the calculations when evaluating the function.

From Pythagorean triples to the unit circle. Learners use the Pythagorean Theorem to find Pythagorean triples and then relate their work to the unit circle in a fun algebra project. Their discovery that x^2+y^2 is always equal to one on...

Now your lesson will be complete. Scholars first review the process of completing the square to rewrite quadratics in vertex form. The method shown here is to first take half of the coefficient of x and finding the perfect square, then...

Tackle a common misconception using a performance task. Dividing by a variable to eliminate a variable may seem like a good idea, but simplifying the variable eliminates solutions as well. Learners develop algebraic and graphical support...

Jump at the chance to use a crazy fun resource. After viewing a short movie clip of a motorcycle stunt, scholars determine whether the motorcyclist will clear a row of buses. They'll likely use a graph of a quadratic function to make...
