Conquer any irrational fears you might have of irrational numbers. As class members investigate how to represent numbers geometrically, they learn about rational and irrational numbers, including approximating and ordering rational...

Second graders explore estimation and place value. For this place value lesson, 2nd graders estimate and construct numbers while working with spider activities. Students use addition and subtraction to compare estimates. Resources and...

Budding mathematicians explore the concept of skip counting. They practice skip counting as they use it to determine the number of wheels that come to school at 3 different times throughout the day. They also create a data graph to show...

High schoolers explore the concept of probability.  In this probability lesson, students use area to determine probability.  High schoolers use charts and spinners to help determine the probability of events such as flipping a...

A simple question, with a not-so-simple answer. Working with whole and mixed number measurements in inches, feet, and yards presents a problem with many possible solutions. A great activity that challenges the minds of young...

Compare Beethoven's fifth symphony to latin music and disco. Learners will listen to and discuss the elements found in the first part of Beethoven's composition. They'll then look for the same elements in Tito Puente and Bee Gees songs....

Students determine speed by running or walking a given distance and dividing the distance by the time it took them to do so. They record their average speed and compare it with the speeds of other moving objects.

High schoolers learn the meaning of LD50 through lecture and discussion. Through experiment, students graph and calculate the LD50 of salt on fresh water amphipods. High schoolers compare results of the experiment with pesticides and...

An informative module highlights eight polynomial concepts. Learners work with polynomial functions, expressions, and equations through graphing, simplifying, and solving. 

In this real-world example, algebra learners start to get a sense of how to represent the relationship between two variables in different ways. They start by looking at a partial table of values that define a linear relationship. They...

Elementary schoolers make and use bar graphs to picture information. They learn how choosing the right scale for a bar graph can help make a persuasive argument. This is a terrific lesson on graphing which should excite your kids. There...

The real value of education is highlighted in more than one way on a worksheet designed to not only add, subtract, multiply, and divide decimals to hundredths, but also to address the correlation between higher pay...

Graph inequalities and discuss the difference in their slopes. Learners observe rate of change as they compare linear, quadratic, and cubic functions.

Students discuss background information presented by the teacher and read dictionary definitions for the words "organic" and "synthetic." In this gardengin lesson, students complete a worksheet on the material. Students grow and compare...

Sprouting scientists explore the concept of density by making mass and volume measurements for five different liquids. From these measurements, they calculate densities. They apply their learning to explain Galileo's thermometer works...

Learners compare weather data and draw conclusions. In this climate change lesson plan, students determine whether data collected over a period of ninety years shows a warming trend. 

Pupils are introduced to the concept of probability. In groups, they make a prediction about how many times a coin might show heads or tails when flipped. They carry out the experiment and record their results to compare it to their...

Students determine how to make the largest sum of money using the least amount of coins. In this mixed currency instructional activity, students listen to a reading of If You Made a Million by David M. Schwartz before participating in...

Learners use 2 sets of colored beans to represent the genes of an organism. In this genetic probability lesson plan, students use the colored beans to represent the genotypes of offspring which they pull out of a box at random while the...

Seventh graders are shown a variety of advertisements and commercials and note the product being sold. As a class, they compare and contrast their answer to the actual product. To end the instructional activity, they discuss whether or...
