Open this lesson by demonstrating the production of acidic carbon dioxide gas by activated yeast. Emerging ecologists then experiment with seashells to discover the effect of ocean acidification on shelled marine organisms. They measure...

Introduce your class to ekphrastic poetry with an exercise that asks them to examine Edward Hooper's painting House by the Railroad and Edward Hirsch's poem "Edward Hopper and the House By the Railroad." After a close reading...

If you're looking to start a unit based around narrative writing, make sure to consider this resource while you're planning. This book covers five topics: writing personal narratives, writing narratives about others, writing...

Here's a must-have packet for your curriculum library. If you are interested in Fahrenheit 451, if you are interested in Ray Bradbury, if you are interested in censorship, if you interested in programs that make a difference, then...

This annotated bibliography and list of websites are valuable resources for any study of the Holocaust and/or of Elie Wiesel's Night.

How did jazz influence Ralph Ellison's Invisible Man? Class members read some of Ellison's non-fiction writings about blues and jazz, listen to records, watch videos, and engage in student-centered discussions. They then produce podcasts...

We would be lost without maps! How are they made? Introduce junior topographers to LIDAR technology with a fascinating activity. Set up a mock city, then have learners operate a laser measure to determine the shape of the landscape using...

Good discussion questions, quizzes, and tests teach as well as assess. Readers of The Great Gatsby will learn much from the materials in a 36-page packet designed to help students prepare for the AP Literature exam. Included in the...

Lead your class on an exciting journey through the world of math as they review geometry facts and solve for unknown angles. They learn how to use auxiliary lines and congruent angles to correctly complete each practice problem...

Medians, midsegments, altitudes, oh my! Pupils study the properties of the median of a triangle, initially examining a proof utilizing midsegments to determine the length ratio of a median. They then use the information to find missing...

Whether you are learning or teaching American Sign Language, a thorough resource on the ways to depict different hand symbols is sure to enhance your journey into proficiency. With sections on different hand symbol groups, including...

Young mathematicians examine area of different figures with the same cross-sectional lengths and work up to volumes of 3D figures with the same cross-sectional areas. The instruction and the exercises stress that the two...

Trace the links between a variety of math concepts in this far-reaching unit. Ideas that seem very different on the outset (like the distance formula and rigid transformations) come together in very natural and logical ways. This...

Provide your emerging mathematicians with the tools to learn as they incorporate auxiliary lines to solve unknown angle proofs in this continuing segment. They decipher information from a diagram to uncover the missing pieces and...

Are pyramids and cones similar in definition to prisms and cylinders? By examining the definitions, pupils determine that pyramids and cones are subsets of general cones. Working in groups, they continue to investigate the relationships...

Can your third graders spot the differences between these geometric shapes? After studying several sections of triangles, rectangles, and other polygons, learners circle the shape described in each set of instructions. For extra...

Young scholars examine elastomeric polymers in a lab activity in which they design a bungee cord. Students must determine the tensile strength, percent elongation, and plot stress versus strain graphs for their experiments on rubber...

Use this comprehensive pre-instruction assessment tool to focus your teaching where your class needs it most. Multiple choice questions assess your budding geometers' conceptual and vocabulary knowledge, but they do not solve any...

Where did conic sections get their name? The equation and graph of a parabola are developed from the definition of the conic section. Teacher examples on graphing the equation and writing an equation from the graph round out the plan.

Can you follow a composition of transformations, or better yet construct them? Young mathematicians analyze the composition of dilations, examining both the scale factor and centers of dilations. They discover relationships for both...

Identifying and verifying reproducible patterns in mathematics is an essential skill. Mathematicians identify the relationship of sides when an angle is bisected in a triangle. Once the pupils determine the relationship, they prove it to...

Make the irrational rational again! Continuing the theme from previous lessons in the series, the lesson relates the polynomial identity difference of squares to conjugates. Learners develop the idea of a conjugate through analysis and...

Teach how graphic designers can use mathematics to represent three-dimensional movement on a two-dimensional television surface. Pupils use matrices, vectors, and transformations to model rotational movement. Their exploration involves...

Everyone knows that opposite sides of a parallelogram are congruent, but can you prove it? Challenge pupils to use triangle congruence to prove properties of quadrilaterals. Learners complete formal two-column proofs before moving on to...
