Complex Numbers

Put on your thinking caps because middle school math has never been more interesting in this huge resource full of thought provoking questions. Written as a newsletter, the resource has 10 two-page newsletters with a variety of...

Individuals learn to divide and conquer complex numbers with a little help from moduli and conjugates. In the second lesson on complex number division, the class takes a closer look at the numerator and denominator of the multiplicative...

Double win with a comprehensive learning exercise and an excellent worked out answer key. The learning exercise itself is twelve pages and begins with the simple sine and cosine graphs, then, develops into the reciprocal trig...

Keep your mathematicians engaged using this group linear functions activity. Each of ten groups receives two graphs with both an image and equation, as well as a "who has" phrase to call out the next graph. Scholars stay on their toes as...

How many ways can you graph a quadratic? The video shows two approaches to graphing a quadratic expression that is initially in standard form. The first method finds the vertex using -b/2a. The second approach is to find (h,k). 

Bypass the table and go straight to the graph. A short video shows one example of graphing a direct variation equation with a negative slope by using the same method as graphing an equation in slope-intercept form. Pupils see it's easy...

Help learners recognize the characteristics of a quadratic graph and how changes affect them. An informative video uses a graphing calculator in order to find out what happens when the leading coefficient of a quadratic...

Show your class how to use properties to make graphing easier with a resource that explores the graphs of quadratics. Using tables to determine the points to graph, pupils discover the symmetry of parabolas in...

Sketch graphs with the Graph Sketcher. Scholars graph functions on a coordinate plane. An interactive makes it as easy as inputting the function and clicking a button.

We have calculators, so why do we have to do this by hand? The video takes viewers through graphing scientific data by hand to create a scatter plot. The process includes labeling axes, writing an appropriate title, determining a...
