Practice makes perfect and perfecting those trigonometric functions are vital in trigonometry. The task requires evaluating cosine and sine values at common degree measures before looking at the results. Is there a pattern when the...

Learners solve 14 word problems and 25 weight conversions.

Find the area; scholars examine nine images of squares and rectangles with width, length, and units provided for each. They multiply double-digit numbers to find the area, writing it into the box provided. Because square units are...

Your learners can approach this task algebraically, geometrically, or both. They analyze the building of a linear function given two points and expand the concrete approach to the abstract when they are asked to find the general form of...

Expand your knowledge of exponents with an activity that promotes critical thinking and comparison skills. Middle and high schoolers compare numbers written in expanded and exponential form and explain their strategies for solving...

Uncover the relationship between factoring quadratics and higher degree polynomials. Learners develop their factoring skills through repetition. A comprehensive lesson begins with quadratics and shows how to use the same patterns to...

Scholars determine how two quantities vary with respect to each other. They complete a fill-in-the-blank activity by stating whether the entities vary directly, inversely, or jointly, create equations that match different variations, and...

Imagine having the opportunity to create your own country. After responding to questions about chapter two, readers of George Orwell's dystopian classic are given a chance to design a utopia for one-million people, complete with...

A political cartoon is timely and thought-provoking. Learners analyze the symbolism found in the cartoon as it relates to current tensions between North and South Korea. Three in-depth analysis questions guide and stimulate class...

Review the multiple methods of solving quadratic equations through an analysis of the discriminant. Scholars use the discriminant to determine the best solution method and then solve various equations. As a challenge, learners build...

Pupils learn the steps for basic constructions using a straightedge, a compass, and a pencil. Pairs develop the skills to copy a segment and an angle, bisect a segment and an angle, and construct parallel and perpendicular lines.

Put those numbers to work by completing a statistical study! Pupils finish the last two steps in a statistical study by summarizing data with displays and numerical summaries. Individuals use the summaries to answer the statistical...

Score a resource on ratios. Young mathematicians learn about different ways to express ratios. Using sports data, they write statements about the statistics in ratio form.

Here's a perfect way to introduce perfect squares. Individuals color in the diagonals of squares and record observations about patterns. They connect their diagrams to exponents of two and perfect squares.

Six word problems provide practice for young geometers to review angles, the angle a of straight line, circles, right angles, and others. I like the approach of these questions; they require thinking and explaining, not just computation.

Here is a top-notch handout to supply your chemistry class with. It covers valence electrons, Lewis diagrams, the octet rule, and more! Technically it is less of a worksheet than a detailed explanation of these chemical bonding concepts....

Translate the process of protein synthesis to your molecular biologists with this instructional activity. It consists of reading, completing a table as a summary, comprehension questions, and a modeling activity for both transcription...

Learners investigate why theoretical probability doesn't always match reality. The activity involves using Python 2.7 (or Sage) to set up a Bernoulli Trial. It also involves setting up a spreadsheet to simulate the Birthday Paradox....

Does a shape's perimeter always match its area? Learners approach this and other claims in this shape investigation worksheet. Using blank grids, they draw various shapes based on required perimeter and area measurements, labelling the...

Kids consider the characteristics needed to be reformers like Martin Luther King and Cesar Chavez. They read a series of quotes focused on both animal and human rights to answer eight critical thinking questions. 

Do some of your writers need an extra lesson on correcting run-ons and comma splices? This worksheet clearly defines the terms, provides models of run-on sentences, comma splice errors, and how to correct them. The second page of the...
