After reading about polymer materials, engineer trainees examine how plastics have been integrated into everyday products. In groups, they compile a list of products made entirely without plastics and then, as a closing activity, try to...

Build upon linear functions to learn about quadratics. The instructional activity introduces the concept of zeros for quadratic functions and makes the connection to the linear factors of the function. It presents quadratics in both...

Explore the multiple meanings of common homographs with this fun language arts activity. Given a series of word webs and a pile of definition cards, pupils complete each web by matching four different definitions to each target word.

Count with ten frames in a first grade addition lesson. Kids determine how to identify numbers on a number line, as well as with ten frames, and complete ten frames to show their answers in several addition problems.

The history of women's education can be traced back to the delicate stitching of student samplers from the 19th century. Modern-day pupils examine and analyze four primary sources, three of which are images of embroidered samplers, which...

Invite your class to consider how to respond to a conflict. Designed to be used alongside Secret Saturdays by Torrey Maldonado, a lesson plan focuses on a set of terms: conflict, escalate, deescalate, conflict resolution, denial,...

Put another set of eyes on your class's historical fiction narratives with one of the final lessons in the unit. Fourth graders use feedback from their peers to annotate their drafts for revision, particularly their bold beginnings and...

Here is a mid-unit assessment for a group of lessons studying the Universal Declaration of Human Rights (UDHR). The first half of this instructional activity calls for several forms of review. Your class will review the content of the...

Should the standard deviation be used for all distributions? Pupils know that the median is a better description of the center for skewed distributions; therefore, they will need a variability measure about the median for those...

Here is a lesson plan in which pupils connect themes and rules to live by from the story Bud, Not Buddy by Christopher Paul Curtis to those found in the poem If by Rudyard Kipling. First, scholars discuss their reading and review Bud's...

Be ready mathematicians of every level. This lesson leads to the discovery of the zero product property and provides challenges for early finishers along the way. At conclusion, pupils understand the process of using the zero product...

Examine the process of rotating images to visualize effects of changes to them. The fifth lesson of 18 prompts pupils to rotate different images to various degrees of rotation. It pays special attention to rotations in multiples of 90...

Is it possible to add infinitely long decimals? As pupils complete the examples in the ninth lesson of this 25-part series, they determine that adding these decimals cannot be done without error. Their task is then to determine the size...

Pencil in the resource on writing verbal phrases into your lesson plans. The 15th installment of a 36-part module has scholars write verbal phases for algebraic expressions. They complete a set of problems to solidify this skill.

Develop another way to find the equation of a line. The lesson introduces the procedure to find the equation of a line given two points on the line. Pupils determine the two points from the graph of the line.

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...

Examine the various rigid transformations and recognize sequences of these transformations. The lesson asks learners to perform sequences of rotations, reflections, and translations. Individuals also describe a sequence that results in...

Combine total quantities and equivalent ratios in problem solving. The fifth lesson in a series of 29 presents problems that can be solved using equivalent ratios. Pupils use part-to-part ratios and either sums or differences of the...

It's scary how fast bacteria can grow — exponentially. Class members solve exponential equations, including those modeling bacteria and population growth. Lesson emphasizes numerical approaches rather than graphical or algebraic.

Not all linear functions are linear transformations, only those that go through the origin. The third lesson in the 32-part unit proves that linear transformations are of the form f(x) = ax. The lesson plan takes another look at examples...

Complex solutions are not always simple to find. In the fourth lesson of the unit, the class extends their understanding of complex numbers in order to solve and check the solutions to a rational equation presented in the first lesson....

Doubling a network or combining two networks is quick and easy when utilizing matrices. Learners continue the network example in the second lesson of this series. They practice adding, subtracting, and multiplying matrices by a scalar...

Discover the connection between vectors and translations. Through the lesson, learners see the strong relationship between vectors, matrices, and translations. Their inquiries begin in the two-dimensional plane and then progress to the...

Investigate how long-run outcomes approach the calculated probability distribution. The 10th installment of a 21-part module continues work on probability distributions from the previous lesson. They pool class data to see how conducting...
