Use the power of mathematics to find the number of red chips in a bag — it's a little like magic! The activity asks learners to collect data to determine the percentage of red chips in a bag. They calculate the margin of error and...

It's assessment time! Determine your young mathematicians' understanding of elapsed time with this brief, five-question quiz.

Sew up your unit on operations with decimals using this assessment task. Young mathematicians use given rules to determine the amount of fabric they need to sew a pair of pants. They must also fill in a partially complete bill for...

The teacher demonstrates how to use a graphing calculator to create box-and-whisker plots and identify critical points. Small groups then create their own plots and analyze them and finish by comparing different sets of data using box...

Do I stand or do I sit? The class plays a dice game where they must decide to either continue to stand and play or sit down and keep their points. After the game, groups discuss individuals' strategies and see connections to the...

Students explore the concept of percentages. For this math lesson, students throw paper at wastebaskets as if shooting a basketball in a hoop. Students shoot the paper a given amount of times and then calculate their shooting percentage....

Learners compute the standard deviation for a given set of data. In this measuring dispersion lesson plan, students compute the mean, and then the distance from the mean for each data point. They find the standard deviation of the data.

Is baseball really the road to riches? Here, statisticians look at salary data from baseball players and use variance to measure the spread of the data to more accurately answer that question. Note: The salary data provided is from 1994,...

Students see that there are mathematical rules that can affect our use of the English language. Calculate the probability of picking any letter at random from a piece of English literature.

Students open a blank spreadsheet and format it for a class survey about the number of shoes owned by the men and women in the class. They enter the data before finding the mean, median, mode, quartiles, variance, and the standard...

Students use a spreadsheet to compute landmark statistics of a math quiz. This lesson can be ongoing throughout the school year and it integrates mathematics curriculum and technology in a simple format for student use.

In this scatter plot worksheet, students examine tables and write a linear equation that matches the table.  Students graph linear equations.  They read scatter plots, determine the trend line, and write a linear equation to...

Students perform different activities to better explain that the word "Average" has 5 different meanings.

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...

Compare different random sampling types using an archaeological setting. Scholars collect data from an archaeological plot using simple random samples, stratified random samples, systematic random samples, and cluster random samples....

To understand how biased data is misleading, learners analyze survey data and graphical representations. They use that information to design their own plans to collect information on consumer thoughts about Chocolicious cereal. 

Seeing is believing. Given several bivariate data sets, learners make scatter plots using the online SeeIt program to visualize the correlation. To get a more complete picture of the topic, they research their own data set and perform an...

How do you find the area of an irregular shape? Class members calculate the area of an irregular shape by finding the area of a random sampling of the shape. Individuals then utilize a confidence interval to improve accuracy and use a...

Become a bean counter. Pupils use a fun activity to design and execute an experiment to determine whether they can grab more beans with their dominant hand or non-dominant hand. They use the class data to create scatter plots and then...

Youngsters count, classify, and estimate quantities using buttons after a read aloud of The Button Box by Margarette S. Reid. They discuss the difference between guessing and estimating. Based on an experiment, they predict the...

Students are presented with the problems of percentages and focus upon numbers in contrast to 100. They calculate problems with money and are engaged with the use of games as a teaching tool. Students also interpret data as presented in...

What's that buzzing in your ear? An insightful lesson about genetically modified mosquitoes! Partnered pupils explore the creation, release, and monitoring of mosquitoes designed to reduce the mosquito population. After watching a video,...
