Seventh grade statisticians randomly select five states and then determine the mean area. The class then works together to create a dot plot of their results. 

Construct tangent lines and make the connection to tangent functions. An informative lesson reviews the geometry origins of the tangent function. Pupils use that information to determine how to construct a tangent to a circle from a...

Middle schoolers compute measures of central tendency.  In this range, mean, median and mode lesson, students gather information on the internet, organize the data and then compute the measures of central tendency.  They create...

Fourth graders investigate when to find the mean, median, mode and range.  In this statistical concepts lesson plan, 4th graders collect data, make observations and graph the data. Students verify their work on the computer.

For this confidence interval worksheet, pupils examine given statistical information to find the margin of error. They construct a confidence interval for the population and find the mean. Seven statistical problems are available on this...

The instructional activity focuses on the ideas of dot plot representations and the mean absolute deviation of data sets.

Statisticians analyze a data set of student IQs by finding measures of central tendency and dispersion such as mean, median, mode, and quartiles. They practice using a graphing calculator to find the values and analyze box plots and...

Fourth graders compare two sets of data by using a double bar graph. In this data analysis instructional activity, 4th graders study a double bar graph and complete questions based upon the data. Students construct a table to show the...

The class gets their mean and median all in a row with an assessment task that uses a population of ducklings to work with data displays and measures of central tendency. Pupils create a frequency chart and calculate the mean and median....

Work it out — find the average time clients spend at a gym. Pupils use a table of random digits to collect a sample of times fitness buffs are working out. The scholars use their random sample to calculate an estimate of the mean of the...

How confident are you? Explore the meaning of a confidence interval using class collected data. Learners analyze data and follow the steps to determine a 95 percent confidence interval. They then interpret the meaning of the confidence...

Investigate dilations to learn more about them. The second segment in a series of 16 provides a discussion of properties of dilations by going through examples. The problem set provides opportunities for scholars to construct dilations.

Students respond to survey questions, discuss results, brainstorm ways to represent survey information, and create table of class results. They find mean, range, and percentages, and create graph to display results.

High schoolers problem solve the mean and median of agricultural data by completing a worksheet. They discuss the results of the statistical data.

In this data analysis worksheet, middle schoolers interpret data in 5 problems involving graphs, tables, and scatterplots. Students construct 1 stem and leaf plot and find the mean, median, and mode of a data set.

Students collect data about energy usage and use mathematical calculations to analyze their data. In this energy conservation and statistics math lesson, students survey their homes to complete an energy usage worksheet. Students...

Breaking the rules is one thing, proving it is another! Learners expand on their previous understanding of congruence and apply a mathematical definition to transformations. They perform and identify a sequence of transformations and use...

Learners see application of construction techniques in a short but sophisticated problem. Combining the properties of inscribed triangles with tangent lines and radii makes a nice bridge between units, a way of using...

Student identify the solution using geometric mean. In this geometry lesson, students create right triangles where the altitude of the triangle is the side containing the right angle. They modify shapes using Cabri software and observe...

Students solve problems using geometric means. In this geometry lesson, students create altitudes in right triangles. They use Cabri software to move the triangle around and observe different sides and angles.

Seventh graders construct frequency tables and box-and-whisker plots. After constructing tables and plots, they take a quiz on mean, median, mode, range, scientific notation, and number properties.

Students make their own puzzle grid that illustrates the number of sit-ups students in a gym class did in one minute, then they make a histogram for this same data. Then they title their graph and label the scales and axes and graph the...

Students make origami frogs to race. After the race they measure the distance raced, collect the data, enter it into a chart. They then find the mean, median, and mode of the data. Next, students enter this data into Excel at which time...

The mean might not always be the best representation of the average. The assessment task has individuals determine the measures of center for the salaries of a company. They determine which of the three would be the best representation...
