As many writers know, you are your own worst editor. The 10th installment in the Writing the Paper series explains that getting feedback from others is crucial to the writing process. The handout highlights the best time to ask others to...

Class members investigate how positive and negative numbers are useful in the real world. Individuals first read a short passage and identify terms indicating positive and negative numbers. They consider situations involving positive...

Many glands work together to control hormone levels in the body. The interactive focuses on the thyroid gland, pituitary gland, and the hypothalamus. It demonstrates the interconnections and feedback loops present in the endocrine system.

When is the trigonometric value of a negative angle the same as the positive angle? Pupils compare the values of trigonometric functions for different angles and their negatives. The interactive resource provides a visual display to make...

How much negative feedback does a body get daily? The interactive walks through one negative feedback loop, increasing body temperature. Then it challenges scholars to relate this to mechanical feedback loops and disorders that prevent...

Positive and negative numbers are all around us. Groups read short story contexts and identify a rational number that represents the values in the context. They order the rational numbers and interpret statements of inequality.

Learning about slopes from a hike in the woods is a walk in the park. Scholars slide a cutout of a person to simulate a hike along several paths. Passing through indicated points reveals the type of slope (positive, negative, zero, or...

Eliminate a color by dragging shapes. The interactive provides a graphical color display that allows for pupils to solve a linear system by elimination. Learners combine figures following set rules for positive and negative shapes. The...

Close your eyes and visualize a definite integral. An interactive provides a visualization of a function and definite integral on a closed interval. Pupils move one point of the interval in either the positive or negative direction....

Get a charge out of a great resource! Scholars use an interactive to explore addition and subtraction of integers. They add or remove electrons in an atom model to consider its charge.

Life is like trying to juggle three tennis balls! That's the big idea in a lesson plan that asks freshmen to consider that sometimes juggling the areas of their lives (social/emotion, academic, and career) runs smoothly and sometimes not...

There's no danger in using an exciting resource. Pupils use an interactive to change the slope of a sledding path and see how the equation changes. They then apply information about safe slopes to see if their sledding paths are...

This resource on learning about slopes from A-frames is A-okay. A simple interactive has learners adjust the height and width of an A-frame house, and then calculate the slope of the roof for each situation.

Adolescents explore self-esteem and the various factors that influence a person's sense of self in this four-part lesson series. Through a combination of whole class instruction, small group discussions, and independent work,...

A short video demonstrates the importance of non-verbal communication in the forming of first impressions. Viewers observe the facial expressions, tone of voice, body language, and appearance of job seekers in an interview, then discuss...

Make connections between vectors and matrices through multiplication. Scholars use the interactive to view the effect of multiplying a matrix by a scalar. The interactive displays the resulting matrix and its corresponding column vectors...

The rule is add before multiplying, even with matrices. Pupils use a slider to change the scalar multiplying the sum of two matrices. The interactive displays the resulting solution matrix, and requires scholars answer five questions...

Get two answers from a single equation. Pupils use the interactive to take the square root of nine and see the graphical representation of the two solutions. Individuals realize that solutions to quadratic equations that are solved by...

Slide the coefficients to determine sums of polynomials. The interactive contains sliders to change the coefficients of an addend in a polynomial addition problem. Pupils determine the coefficients of the addend to arrive at particular...

Transcription means a written copy but how can DNA write a message? The video explains transcription and translation as they relate to DNA and RNA. Then in the interactive, scholars practice base pairing and answer analysis...

Use the area of polygons to calculate the area between curves. Pupils calculate areas under income and expense curves by filling the space with squares and right triangles. Using that information, they determine the profit related to the...

Letters of recommendation play a key role in the college admissions process. A handout on the topic, part of a series on specific writing assignments, helps applicants through the process of choosing recommenders and requesting a letter....

An important part of the job search process is the personal interview. Help pupils prepare with speed interviewing activity—teams of three-act as a job seeker, interviewer, and observer. Every three minutes, participants rotate roles and...

Individuals learn how to plot rational numbers on the number line in the sixth lesson of a 21-part module. They identify appropriate units and determine opposites of rational numbers.
