Caffeine affects your heart rate — or does it? Learners study experimental design while conducting their own experiment. They collect heart rate data after drinking a caffeinated beverage, create a box plot, and draw conclusions....

Develop probability distributions from simulations. Young mathematicians use simulations to collect data. They use the data to draw graphs of probability distributions for the random variable in question.

Playing with matches (unlit, of course) becomes an engaging learning experience in this fun instructional unit. Teach pupils how to apply properties of exponential functions to solve problems. They differentiate between quadratic and...

All data is not created equal. Scholars examine the different types of studies and learn about the importance of randomization. They explore the meaning of causation and when it can be applied to data. 

Learn how to analyze probability distributions. The sixth installment of a 21-part module teaches pupils to use probability distributions to determine the long-run behavior of a discrete random variable. They create graphs of probability...

We know that sample data varies — it's time to quantify that variability! After calculating a sample mean, pupils calculate the margin of error. They repeat the process with a greater number of sample means and compare the results.

Challenge your classes to complete an experiment from beginning to end. Learners make their own hypotheses, collect and analyze their own data, and make their own conclusions. They are on their way to becoming statisticians! 

Investigate how long-run outcomes approach the calculated probability distribution. The 10th installment of a 21-part module continues work on probability distributions from the previous lesson. They pool class data to see how conducting...

Will it sink or will it float? Learners predict the outcome as they drop random objects into a container of water. Then, they keep track of the results and record the data in a t-chart to draw a final conclusion.

Learners find the area and perimeter of regular polygons and composite figures and examine the effect on the area and perimeter of a figure if the dimensions are multiplied by a constant. The nine page worksheet contains thirty-seven...

For this probability worksheet, students compute the experimental probability of an event from given data. They give answers in fraction, decimal and percent form. Students compare the theoretical probability to the experimental...

A coin toss is a simple and fun way to help youngsters discovery probability. Preferably in partners, they first predict what would happen if they tossed two coins 48 times. How often would two heads show up? Two tails? How about one of...

Students collect data and analyze it. In this statistics lesson, students make predictions using different outcomes of trials.

What's in a name? Pupils create a data set from the number of letters in the names of classmates. Each group then takes the data and creates a visual representation, such as a histogram, circle graph, stem-and-leaf plot, etc.

Fourth and fifth graders make predictions using data. In this analyzing data lesson, pupils use experimental data, frequency tables, and line plots to look for patterns in the data in order to determine chance. You will need to make a...

The test may say you have cancer, but sometimes the test is wrong. The provided task asks learners to analyze cancer statistics for a fictitious town. Given the rate of false positives, they interpret the meaning of this value in the...

Clean, but captivating, two online simulations demonstrate probability for middle schoolers. They can choose the number of coins and tosses and watch as the results pile up. They can choose from a variety of spinner types and the number...

For some, probability is a losing proposition. The assessment item requires an understanding of fraction operations, probability, and fair games. Pupils determine the fractional portions of an event. They continue to determine whether...

Class members study the size of classmates' feet and perform a statistical analysis of their data. They solve for central tendencies, quartiles, and spread for the entire group as well as subgroups. They then write a conclusion based on...

If a car gets heavier, it goes farther? By running an activity several times, teams experience Newton's Second Law of Motion. The teams vary the amount of weight they catapult off a wooden block car and record the distance the...

Students practice addition facts, record data, and construct a bar graph. In this probability lesson, students participate in a board game in which bicycles move towards a finish line based on players completing addition problems. Dice...

Students practice calculating probability, see how geometry can help solve probability problems and explore platonic solids.

In this central tendency activity, 8th graders solve 10 different problems that include determining the mean, mode, and median of various situations. First, they prepare a frequency distribution with a class interval for the data found...

Students explore the ways Geometry can help solve probability problems. Students describe platonic solids and practice calculating probability using an online resource. They construct dice with various numbers of sides to demonstrate...
