How can opinions slant facts? Workshop participants learn how to examine primary and secondary sources and identify the author's point of view. They also examine how visual art impacts the meaning and rhetoric of sources. Full of...

Is a college education necessary for success in today's world? The class investigates the question, along with others at the end of the sixth workshop in a 15-part series. The lesson has four parts with multiple activities and...

High schoolers investigate linear equations as they use technology (Cabri, Jr.) to explore the equations of lines in slope-intercept form. The technology allows learners to manipulate the line and observe the changes in the parameters of...

Students analyze census data from 1915, 1967 and 2006. They read an article about how the world's population is growing at an alarming rate. They use primary source documents to create a timeline on the information they gathered. They...

Four is the perfect number—if you're talking about parallelograms. Scholars determine a possible fourth vertex of a parallelogram in the coordinate plane given the coordinates of three vertices. They read a conversation...

Students investigate the derivative of a function.  In this calculus lesson, students explore the derivatives of sine, cosine, natural log, and natural exponential functions.  The lesson promotes the idea of the derivative as a...

Help young readers find, identify, and use their voices with a set of empowering activities based on Peter H. Reynolds' trilogy of books. Sky Color, Ish, and The Dot focus on recognizing moods and treating each other...

Where in the world (or at least in the coordinate plane) is the third vertex? Given two coordinate points for the vertices of a triangle, individuals find the location of the third vertex. They read an account of fictional...

Geometric figures are perfect to use for proofs. Scholars prove conjectures about whether given points lie on a triangle and about midpoints. They use a provided dialogue among fictional students to frame their responses.

It seems the post office has run out of stamps! Learners build all the values of postage available if the post office only sells five- and seven-cent stamps. The task provides an opportunity to create an expression in two variables and...

High school economists learn about the stock market in a project where they "buy" and track stocks. The author of this resource reports it is the high point of her 12th grade economics course, but no resources are attached. After viewing...

Students explore the poinsettia and its symbolism as a Christmas flower. Students will listen to a story about the poinsettia and its origins in Mexico and discuss what they know about Mexico. They will discuss the poinsettia's...

Incorporate technology in your classroom by teaching your young scholars how to graph systems of linear inequalities as they apply to an area of land.  The lesson provides an extension in which students are challenged to write a...

Pupils practice examining the tangent to a function to estimate the value of the function near the point of tangency. They view errors associated with those approximations, determine overestimates and find intervals that guarantee a...

Students explore parabolas.  In this algebra and technology lesson, students construct the equation of a specific parabola, then take digital photos of real-life representations of these parabolas.  Students create a podcast...

Students write letters to organizations, such as United States Geological Society, to find out more about rocks. Students write about a pretend time they found a magic pebble. Students calculate distances to travel to see various...

Introduce your class to the narrative, descriptive and expository forms of writing. In groups, they discuss the personality of the author while graphing the characteristics after reading different examples from the same writer. To end...

Third graders describe, represent and compare fractions using pieces of a chocolate bar.  In this fractions lesson, 3rd graders demonstrate how to read and write fractions correctly. Students then integrate technology by using...

Have the class learn about and make conjectures about a line intersecting a cubic.  In this making conjectures about a line intersecting a cubic lesson, students draw lines that intersect a cubic at three different points. ...

With the assistance of their Ti-84/Ti-83 Plus calculators, students develop a foundation for the limiting process as well as estimate limits from graphs and tables of values. They view how a function behaves as the input approaches a...

Pupils explore the concept of pyramids. They determine if two sides of a pyramid are perpendicular using a graphing calculator, then discuss parallel and perpendicular lines and how to determine if two lines are parallel or...

Students produce original tessellations, using equilateral triangles where three unique symmetrical faces rotate, use shape, pattern/repetition, and color to create a striking composition, and create "beasties" inspired by bestiaries of...

First graders identify and demonstrate how symbols and models are used to represent features of the environment. They identify the directions on a map as east, west, north, and south. Finally, 1st graders play a direction game, move to...

Learners use the Pythagorean theorem to discover the relationships between the lengths of sides of a right triangle. In this right triangles lesson plan, students use their reasoning and mathematical skills.
