Seventh graders find the perimeter and area of triangles.  In this finding the perimeter and area of triangles lesson plan, 7th graders find the perimeter and area of triangles given two sides.  Students find the missing side...

Students act out the creation of five tally marks. In this tally mark lesson, students act out how to make tally marks. Four students stand very close together and a fifth student gives them a group hug creating five tally marks.

Fourth graders investigate the concept of geometric patterning. They create their own patterns with a few basic requirements. The patterns must illustrate the concepts of flipping, 90 and 180 degree rotations. The collages also consist...

Students explore weather instruments. In this weather lesson, students make rain gauges, anemometers, and barometers following the instructions given in the lesson. Students set up a weather station using their instruments and record and...

Seventh graders observe and demonstrate how to calculate markups and discounts including markup percentages and discount percentages. They observe a teacher-led demonstration, then in pairs read scenarios and independently complete...

Here is a geometry lessonwhich invites learners to create models using their knowledge of lines, segments, rays, and angles. This lesson reinforces geometric vocabulary and concepts through practical application, it also includes...

Is bigger really better? By the end of this lesson, learners will be able to apply formulas for computing the diameter of tires and wheel assemblies. Begin by showing a slide presentation that will review definitions for radius and...

As a cross-curricular instructional activity, your class examines the issues of gender discrimination, careers, and gender roles. They read and discuss an article, prepare a proof of the Pythagorean theorem as a class, and develop a...

Examine how the economics of a school store relate to real world economics. Elementary students explore various websites, complete a Venn diagram, create a schedule of wages for the students, read the book "A Chair For My Mother" and...

Pupils of all ages work in pairs to find information about themselves and record a digital "Who am I?" They observe and measure each other, write clues, and illustrate before having others guess who is described.

Learners demonstrate their knowledge pictorially, concretely, and abstractly in this unit meant to last three hours over three days. Using hands-on activities, manipulatives,  real-world applications, and problem...

Odd or even—fifty-fifty chance? Pupils first conduct an experiment rolling a pair of dice to generate data in a probability lesson. It goes on to introduce mutually exclusive and non-mutually exclusive events, and how to use the...

Reaction rates vary between your dominant and nondominant hand ... or do they? Young scholars conduct an experiment collecting data to answer just that. After collecting data, they calculate the p-value to determine if the difference is...

Chunking information helps you remember that information longer. A hands-on activity tests this theory by having learners collect and analyze their own data. Following their conclusions, they conduct randomization simulations to...

Just how confident can we be with statistics calculated from a sample? Learners take this into account as they look at data from a sample of petroleum engineer salaries. They analyze the effect sample size has on a margin of error and...

Making inferences isn't an exact science. Using data about salaries, learners investigate the accuracy of their inferences. Their analyses includes simulations and randomization tests as well as population means.

Introduce starting space scientists to the electromagnetic spectrum, expecially the portion of visible light. Teach them about wavelength and frequesncy. Then give them a roll of adding machine tape and a manila folder to make a...

Students design a census class and school, then tabulate the results. They respond to a sample census, then reflect on why questions of race and national origin are different.

Fifth graders define vocabulary terms, identify the characteristics of a pillbug, and create a dichotomous key. Then they examine the pillbugs and make observations and record these observations. Finally, 5th graders observe specific...

Focusing on this algebra lesson, learners relate quadratic equations in factored form to their solutions and their graph from a number of different aspects. In some problems, one starts with the original equation and finds the...

Scholars research arm span to determine who gives the best bear hugs. They use data from a national study to find the standard statistics for arm span. It includes mean, median, quartiles, spread, standard deviation, and more.

Is time on your side? Pupils come up with an experiment to test whether their classmates can guess how long it takes for 30 seconds to elapse. They divide the class data into two groups, create box-and-whisker plots, and analyze the...

Investigate the relationship between height and arm span. Young statisticians measure the heights and arm spans of each class member and create a scatter plot using the data. They draw a line of best fit and use its slope to explain the...
