I'm a fan of clearing the denominator, but solvers can also find common denominators and cross multiply to solve the linear equations on the activity. Each of the six problems has rational coefficients.

Time to practice linear equations. The sectioned worksheet starts with simple linear problems and increases to multi-step and rational coefficient problems. 

The characteristics of parent function vary from graph to graph. Let learners decipher the graph, table of values, equations, and any characteristics of those function families to use as a guide. The nicely organized page...

Enjoy this pre-made worksheet that practices polynomial and rational inequality problems. The problems are all multiple choice, and answers are written in interval notation. The best part? A separate page with all the problems...

Young chemists have unknown compounds they need to sort. Performing three different tests on each, the chemical behaviors they observe become the basis for data analysis. 

The fifth lesson of seven in the series outlines an in-depth analysis of the periodic table. After direct instruction, pupils take turns practicing in the group before beginning independent study. The assessments include a...

Scholars research and present on the historical happenings of 1919. After sharing their findings, pupils debate about how Congress dealt with the moral issues of the time. The evaluation asks learners to write a persuasive...

If your pupils think a catalyst is a list of their cats, then this might be the lesson for you! Young chemists study the effect of temperature, catalysts, concentration, and particle size on reaction rates during four different...

Young chemists grow ionic crystals, metallic crystals, and supersaturated crystals in three different lab experiments. Observing these under a microscope allows pupils to compare the various structures. 

What did the sea say to the boat? Nothing, it just waved. An inquiry-based lesson starts with a simple concept on the Archimedes Principle and challenges pupils to make something out of clay that floats. Then, they design...

Put on your Algebra cap because this review provides practice on topics such as linear equations, rational expressions, and function problems. All the questions are multiple choice, and while the focus is on a few main sections,...

Should identifying a tragic hero be based on a universal definition or a definition based on the morals and values of a specific culture? As part of a study of Things Fall Apart, class members read Sylvia Plath's "Colossus" and then...

Using simple materials, an informative instructional activity demonstrates the Law of Conservation of Matter and explains how to balance chemical equations. Young chemists perform experiments, analyze reactions, and balance...

Young scientists observe the spectra of elements and compare that to the Doppler effect. Hook scholars from the beginning all the way to the extension activities in this 5E-format lesson. 

Geologists are gneiss, tuff, and a little bit wacke. The fifth chapter of seven includes ten activities at four different levels. The hands-on activities cover fossils including how they are formed, vertebrates, invertebrates,...

Geology rocks — literally! A geology chapter offers eleven activities at four different levels. Scholars enjoy completing hands-on experiments before applying critical thinking skills following a share, process, generalize, apply,...

Do you find the idea of having a science fair with all of your students intimidating? Use a guide that provides everything you need to know to make project-based learning manageable. The resource includes options for four...

Young chemists perform an experiment to determine if a compound is iron (II) chloride or iron (III) chloride. Then they determine the formula, balance the equation, and answer analysis questions. 

Starting a year of Algebra I? This mighty packet practices all of the major topics with different ranges of difficulty. Standards include everything from linear to quadratic to rational expressions. Use it in a...

Think inside the box with KenKen® puzzles to provide some problem solving practice. These puzzles are similar to Sudoku, but require computation inside designated boxes. There are multiple puzzles with a range of difficulties to...
