What makes a great networker? Learners explore valuable life skills and interpersonal character traits, and consider how to present oneself in the most effective way during an opportunity to network. 

The brother-sister pair Carlos and Clarita need your class's help in developing their new pet sitting business. Through a variety of scenarios and concerns presented to the siblings, the learners thoroughly explore systems of equations...

Generating a system of shapes. Groups work together to create a number system using three different shapes as symbols. The groups should come up with the rules that generate all the possible permutations of the three shapes.

Factor in different strategies in a lesson for factoring quadratics. Young mathematicians first create tables and area models to factor quadratic trinomials into two binomials by guess and check. Learners then investigate how they can...

Generate interest in current events, the theme of a new unit, or a research project. Individuals select a question from the list generated by the class, conduct one-on-one interviews, analyze the responses, draw conclusions based on...

Introduce cradle-to-cradle design thinking. Scholars first discuss the importance of natural laws and rights. They then use a variety of online and print resources to research eco-efficiency and cradle-to-cradle design.

Everyone does their fair share. The sixth segment in a 22-part unit presents the mean as a fair share. Groups build a conceptual understanding of the mean of a data set, rather than simply learn an algorithm. Learners use the...

Spread the word about seafloor spreading! Junior geologists prove Albert Wegener right in an activity that combines data analysis and deep ocean exploration. Learners analyze and graph fossil sample data taken from sites along the...

Budding poets create two acrostic poems, one for their name and another using a word of their choice. Over the course of five days, scholars compose, revise, publish, and share their work with their peers.

Where did the cherished ideals enshrined in the Bill of Rights originate? While history gives the Founding Fathers much of the credit, laws in colonial America influenced the Bill of Rights. An interactive web-based activity allows...

The first ever minimum wage in America was set at 25 cents per hour in 1938 and has been steadily, if slowly, increasing ever since. Using the provided website, pupils decide if the United States should further increase the federal...

Students create an artwork that uses organizational principles and functions to solve a visual arts problem. The piece creates the illusion of transparency used to unify a work of art that demonstrates that light advances and darks recede.

In this approximation worksheet, students use the Euler's method to interpret a piecewise linear function. They explore why the approximation produced using a smaller stepsize is a better approximation. This four-page worksheet...

For this math worksheet, students find the solutions to the differential equations. Then they examine the group of equations in order to determine the ones that are linear.

In this math worksheet, students write down five exact differential equations in symmetric form. Then they test the statements concerning differential equations.

In this math worksheet, students examine the concepts of generalizing root-finding algorithms and fixed point iteration. They also practice using the Fixed Point Theorem.

For this math worksheet, students examine the concept of orders of convergence for a sequence. They practice finding the different rates of convergence.

In this math worksheet, students use the following descriptions of a spring system to write a differential equation of the form my + γy + ky = F(x).

In this math activity, students explore how the use of implicit differentiation does not give the solutions to the differential equation. Then they write the definitions to the vocabulary related to differential equations.

In this calculus worksheet, students examine a situation form The Simpsons in whcih Bart falls from a tree house.  Students write and solve an differential equation that gives the height of the tree house. The...

In this math worksheet, students suppose that a function f and its derivative f1 are continuous and that there are constants K, a, and M such that |f(t)|< Keat for t ≥ M.

In this sequence worksheet, students explore the convergence of a sequence and the rate of a sequence. They explore problems and identify the order of convergence. This three-page worksheet contains approximately six problems. ...

In this math worksheet, students solve the differential equation by means of a power series about the point x0 = 2. Then they find the recurrence relation and the first four terms.

In this math worksheet, students examine the two springs with spring constants k1 and k2 are attached to a block of mass m. They show the frequency of the oscillations on the frictionless surface.
