Delve into the heart of dramatic dialogue with a unit focused on Oedipus the King by Sophocles. Having completed an online exploration about ancient Greece beforehand, ninth graders read the play's opening lines and analyze how...

The manipulation of time is one of the most essential elements in Sophocles' Oedipus the King. As your language arts class participates in a jigsaw discussion activity, they work together to analyze the play's plot structure and...

The terrible truth begins in a lesson that focuses on the final act of Sophocles' Oedipus the King. As ninth graders collect evidence that details the origin of Oedipus and how his birth relates to the prophecy everyone tried to avoid,...

Was Oedipus' destiny determined by fate or by his actions? Using details from the text, ninth graders delve into a critical thinking exercise based on Sophocles' Oedipus the King. Now that Oedipus has learned his true identity, readers...

Now that readers can see the full scope of Sophocles' Oedipus the King, they can draw connections between the dramatic ending and the textual evidence throughout the Greek tragedy. As they prepare for the unit assessment writing prompt,...

As Oedipus the King approaches its tragic conclusion, high schoolers discuss Oedipus' reaction to seeing his wife's body. They also examine how Sophocles structures the scene to contribute to the central idea of his play.

Lead a discussion on the similarities between the properties of area and the properties of volume. Using upper and lower approximations, pupils arrive at the formula for the volume of a general cylinder. 

What is the relationship between a hemisphere, a cone, and a cylinder? Using Cavalieri's Principle, the class determines that the sum of the volume of a hemisphere and a cone with the same radius and height equals the volume of a...

The only way that a heinous act of genocide can succeed is if citizens of surrounding groups and countries turn their backs on those suffering. A thorough language arts module addresses shared central ideas with three separate units,...

Have you ever wanted to learn more about a subject after you finished a great book? Guide ninth graders through an inquiry-based research project as they finish the first chapter of Temple Grandin's Animals in Translation. Having...

Can segments be considered perpendicular if they don't intersect? Learners look at nonintersecting segments on the coordinate plane and make conclusions about the lines that contain those segments. They determine if they are...

Prove theorems through an analysis. Learners find the midpoint of each side of a triangle, draw the medians, and find the centroid. They then examine the location of the centroid on each median discovering there is a 1:2 relationship....

What do you do when factoring doesn't work? Learners complete the square when faced with quadratic expression that don't factor traditionally. They then use factoring by grouping to solve polynomial equations.

Don't allow those polynomial functions to misbehave! Understand the end behavior of a polynomial function based on the degree and leading coefficient. Learners examine the patterns of even and odd degree polynomials and apply them to...

Pupils learn to solve square root equations and rationalize denominators. Problems include those with extraneous solutions. 

Augment a unit on parabolas with an instructive math activity. Pupils graph parabolas by examining the relationship between the focus and directrix. 

Quadratic solutions come in all shapes and sizes, so help your classes find the right one! Learners use the quadratic formula to find solutions for quadratic equations. Solutions vary from one, two, and complex. 

Turn your class upside down as they explore the reciprocal functions. Scholars use the unit circle to develop the definition of the secant and cosecant functions. They analyze the domain, range, and end behavior of each function.

Don't give your classes the third degree. Use radians instead! While working with degrees, learners find that they are not efficient and explore radians as an alternative. They convert between the two measures and use radians with the...

Build a solid understanding of trigonometric transformations through exploration. Learners work in teams to analyze the effects of different algebraic components on the graph of a sine function. 

Without data, all you are is another person with an opinion. Show learners the power of statistics and probability in making conclusions and predictions. Using two-way frequency tables, learners determine independence by analyzing...

Time to experiment with mathematics! Learners study experimental design and how randomization applies. They emphasize the difference between random selection and random assignment and how both are important to the validation of the...

We know that sample data varies — it's time to quantify that variability! After calculating a sample mean, pupils calculate the margin of error. They repeat the process with a greater number of sample means and compare the results.

Pupils analyze group data to identify significant differences. They use simulation to create their own random assignment data for comparison.
