When presented with categorical data, a two-way frequency table is a great way to summarize the information. Pupils organize categorical data using a two-way table, then use the tables to determine missing data and to calculate simple...

Is assembling the periodic table as simple as Tetris? Scholars arrange colored cards into a logical order and then make connections to the arrangement of the periodic table. Hands-on activities include adding trend arrows and analyzing...

Analyze functions by decomposing complex functions and composing simple functions. Through a detailed lesson plan, pupils learn the vocabulary and notation related to the composition of functions. Practice includes both evaluating and...

Teach solving for unknowns through a problem-solving approach. The grouping of five lessons progresses from finding an unknown through simple reasoning to solving simultaneous equations involving three and four variables. Each lesson...

Use a set of quick and easy to use literacy centers at the beginning of the year as you start to assess your students. The 13-page packet provides writing and reading activities with simple directions that allows new class members...

What's that lurking in the shadows? An activity that demonstrates how eclipses happen. Science scholars investigate how light and distance interact to form shadows. The experiment uses simple materials to generate data and observations...

How much does your class know about the relationship between climate change and carbon dioxide? Science scholars explore the nature of greenhouse gases and rising ocean temperature through demonstrations, research, and experiments. The...

The world in Lois Lowry's The Giver is one without pain or suffering. Similiarly, your classroom review of the novel can be painless with a simple and straightforward crossword puzzle that covers characters, details, and setting...

Is there more to evaporation than just less liquid? Show young scientists the energy transformation that occurs during a phase change through a series of simple experiments. Lab partners place drops of water, ethanol, and ethoxyethane on...

Practice working with number lines with a simple, versatile worksheet. On a number line starting at zero and continuing beyond one, third graders decide where to place the fraction seven-fourths.

What better way is there to introduce conservation of mass than a few simple experiments? Young chemists conduct two chemical reactions, take the masses of reactants and products, then compare their results to determine...

Look for 11 words associated with Thomas Jefferson and his life in a simple Jefferson-themed word search. It includes words like Monticello, Louisiana Purchase, George Clinton, and Thomas Jefferson.

Adjectives can come before or after the noun they describe. Eight simple sentences prompt learners to circle the noun that each underlined adjective is describing.

It's a sign! Scholars analyze sine functions for patterns in their periods. The exploration advances beyond a simple function to the combination of two functions with even and odd coefficients. Their goal is to find a pattern between the...

From linear to quadratic with a simple operation. An exploratory lesson challenges learners to find two linear functions that, when multiplied, produce a given parabola. The task includes the graph of the sum of the functions as well as...

The task is simple, but the solution is a little more complex. Learners must find the smallest number that results in a perfect square when multiplied by two and a perfect cube when multiplied by three. The task requires an analysis...

What? The calculation of area is a linear distance? A short video shows how to use the areas of simple polygons to estimate the area under a graph. Pupils divide the area under a curve into figures to easier calculate the area. Given...

Make the complicated look relatively simple. The video shows how multiplication of algebraic fractions is easier when they factor the numerators and denominators. Pupils see which factors will cancel, or divide out, easier when writing...

Take a rational look at solving equations. Learners watch a video presentation on solving simple rational equations that shows solving the equation along with finding excluded values. Viewers then practice the skill with the worksheets...

Take the difficulty out of classifying matter with an easy-to-follow activity that makes distinguishing between pure substances and mixtures simple. Scholars explore how matter is grouped between two categories—pure substances and...

Chances are high that the class will probably like the lesson. Pupils view an introduction to probability and use the information to find probabilities of simple events based on the sample space. Scholars then use their knowledge of area...

Simple images of everyday activities are arrayed for primary learners to evaluate. For each, they determine whether or not the activity will increase one's heart rate. They draw a circle around those that do, a box around those that...

Complex solutions are not always simple to find. In the fourth lesson of the unit, the class extends their understanding of complex numbers in order to solve and check the solutions to a rational equation presented in the first lesson....

Translating complex numbers is as simple as adding 1, 2, 3. In the ninth lesson in a 32-part series, the class takes a deeper look at the geometric effect of adding and subtracting complex numbers. The resource leads pupils into what it...
