What do geometric squares have to do with quadratic equations? A lesson on solving quadratic equations by completing the square teaches middle and high schoolers how to use algebra tiles to create squares. They then use what they learned...

Explore the science behind Earth's amazing diversity of life with this lesson on genetics. Looking at specific traits in piebald deer, carnations, and roan cattle, young scientists use Punnett squares to determine the possible genotypes...

Young analysts use real (provided) data from a class's test scores to practice using statistical tools. Not only do learners calculate measures of center and spread (including mean, median, deviation, and IQ range), but also use this...

Familiarize young mathematicians with the radical concept of square roots using this set of skills practice problems. Building on prior knowledge about combining like terms in algebraic expressions, this worksheet helps students learn...

Get things moving with this extensive collection of physical science resources. Covering the fundamentals of measurement, graphing, lab safety, and experimental design as well as the specific scientific concepts of velocity,...

Learners perform data analysis and draw conclusions bound to stir lively debate in a statistical activity. Starting with data comparing men's and women's wages, the class performs two different kinds of regressions to determine trends....

This first of twelve algebra 2 resources provides a broad review of many algebra 1 concepts through a number of separable lessons and labs. Starting with the real number system and its subsystems, the sections quickly but thoroughly move...

Late in algebra 2 or early in pre-calculus, learners are developing a kind of functional intuition. This worksheet goes a long way toward training this skill by helping to expose patterns of transformations through both general and...

As an introduction to the lesson plan, learners verify the Pythagorean theorem with a hands-on proof. Then, pupils use the theorem to determine whether three side lengths could form a right triangle and choose one of two real-life...

Help your class develop a greater understanding of the area of a right triangle. The video starts by reviewing the area of a rectangle and noting that the rectangle is made up of two congruent triangles. Learners are then shown that in...
