Solving these percent problems is a matter of counting. Pupils find percents by counting the number of events that meet the criteria and the total number of possibilities. Participants create the ratio and convert it to a percent to...

Watch the damage from a forest fire in this interactive simulation activity that challenges learners to estimate the burn area using different approaches. Learners are given a worksheet to track the different burn patterns and practice...

Display data over a larger interval. The fourth segment in a 22-part unit introduces histograms and plotting data within intervals to the class. Pupils create frequency tables with predefined intervals to build histograms. They describe...

Can you prove it? Making assumptions in geometry is commonplace. This resource requires mathematicians to prove the parallel line postulate through constructions. Learners construct parallel lines with a 180-degree rotation and then...

Corresponding parts, congruent parts, congruent corresponding parts—what does it all mean? The resource challenges pupils to identify corresponding parts for pairs of figures. It uses examples of figures that undergo rigid...

Show scholars the importance of recognizing a normal curve within a set of data. Learners analyze normal curves and calculate mean and standard deviation.

Students design their own spinner that meets the given criteria. In this math lesson, students discuss biased versus unbiased events or outcomes when dealing with probability. Students are given 5 criteria that must be incorporated into...

Students evaluate equations and identify graphs. In this statistics lesson, students identify plotted points on a coordinate plane as having a positive, negative or no correlation. They complete basic surveys, plot their results and...

Seventh graders examine force and motion. In this seventh grade mathematics/science lesson, 7th graders collect and analyze data regarding the use of an atlatl to throw a spear. Students describe and analyze the motion which leads to the...

Third graders discuss prizes included in products to stimulate sales. They discuss a pretend pretzel company and it's sticker promotion. Students compute how many boxes of pretzels they will need to collect in order to be sure of having...

Second graders use tree diagrams to predict the possible outcomes of coin tosses. The data they collect and graph also help them predict the likelihood of getting heads or tails when tossing coins the next time.

Students explore probability by participating in an experimental activity. In this number statistics lesson, students collaborate in groups in which they move a game piece around a board. Students calculate their probability of landing...

Fourth graders predict future outcomes with an investigation of the mathematical principle of probability using spinners constructed by them. The spinner is a hands on application an they combine it with writing a ratio for the...

Fourth graders analyze the data in a bar graph, pictograph, line graph, and a chart/table and draw conclusions based on the data. They discuss each type of graph, write questions for each graph, and analyze the data as a class.

First graders explore data collecting and graphing. In this data collecting and graping lesson, 1st graders watch a video about monster who sells pancakes. Students make a graph to record the most popular pancake. Students also play...

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

Explore the concept of mean, median, and mode with pupils. They estimate the length of a string or the number of M&M's in a jar. Then find the mean, median, and mode of the class' estimates.

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.

Explore linear programming on a website game. Partners solve a real-world problem by setting up an objective function and a linear inequality. They graph their results on chart paper and also using a calculator before presenting their...

Sixth graders interpret linear and nonlinear graphs. They create graphs based on a problem set. Next, they represent quantitive relationships on a graph and write a story related to graphing.

Introduces your class to random processes in networks with an activity that uses information about disease spread using the susceptible, infectious, resistant (SIR) model. Participants determine whether a susceptible person becomes...

After examining how a spring scale works, teams work together to design their own general measurement device. Reading material provides background information, but there is no part of the procedure in which learners handle an actual...

If you have or can create a set of tiles, numbered one through eight, then you can implement this hands-on lesson about probability models. Individuals draw a tile from a bag, record its number, and then return it to the bag. They...
