But this is math—we don't need to know how to write! The article makes a point that class members in AP® Statistics should be comfortable writing as the exams require it. Individuals quickly realize that quality writing is crucial...

Determine whether it is right or not. Using the Pythagorean Theorem, the video shows how to determine whether a triangle is a right triangle. Pupils practice the skill in a few of the problems in the associated worksheets on the...

Discover relationships between linear and nonlinear functions. Initially, a set of data seems linear, but upon further exploration, pupils realize the data can model an infinite number of functions. Scholars use multiple representations...

Explore the effect of outliers through an analysis of mean, median, and standard deviation. Your classes examine and compare these measures for two groups. They must make sense of a group that has a higher mean but lower median compared...

What do Sherlock Holmes and geometry have in common? Why, it is a matter of deductive reasoning as the class learns how to justify each step of a problem. Pupils then present a known fact to ensure that their decision is correct.

Write, edit, and then revise! The fourth lesson in a five-part series asks peers to provide feedback on research. Individuals then use the research to edit and revise conclusions and develop their presentations.

A change is coming. Pupils use unit cubes to investigate how changes in the length, width, and/or height affects volume and surface area. They extend the results to write and test predictions on the effect of changing multiple sides on...

Explore business problems through mathematical analysis. The task has individuals write and graph a linear system to determine the best business model. They use their models to answer a series of questions that help to make a conclusion.

Test your pupils' reasoning skills with several activities and a quick mystery to solve. Learners watch and analyze a few video clips that demonstrate reasoning in action, practice deduction with an interactive and collaborative...

Does your coffee get too cold too fast? Joulies just might be your answer! Learners use experimental data to make a conclusion about how effective Joulies are at keeping coffee at the ideal temperature. A video shows the graph of the...

Quickly get to the decimal point. The last assessment in a nine-part series requires scholars to work with decimals. Pupils compare the race times of several athletes and calculate how much they have improved over time. During the second...

If there is a conditional statement, then there is a hypothesis and conclusion. Pupils learn how to identify the parts of conditional statements. Class members continue to work with conditional statements and rewrite them in their many...

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...

Wearable devices have become more the norm than the exception. Learners analyze data from a sample device with a regression analysis in a helpful hands-on lesson. Their focus is to determine if there is a connection between temperature...

Math scholars investigate the cost of living in Hong Kong compared to Chicago but must first convert the different types of currency. They then choose a type of graph to compare different spending categories and finish the activity by...

Buying a new sofa? Learn how to use the Pythagorean Theorem, as well as algebra and graphing techniques, to determine whether the sofa will fit around a corner (which I'm sure you'll agree is a very important consideration!).

Can you graph your story? Keep your classes interested by challenging them to graph a scenario and interpret the meaning of an intersection. Be sure they paty attention to the detail of a graph, including intercepts, slope,...

How hard can it be to measure out two pounds? A short performance task introduces a situation where a balance scale is broken. It gives a method for measuring out two pounds and asks learners to evaluate the procedure. They must prove...

"Statistics is the grammar of science" -Karl Pearson. In the assessment task, learners read a claim made by a newspaper and analyze its conclusions. They need to think about the sample and the wording of the given statistics.

Unlike mathematics, statistics comes with a context. The author reminds teachers that data analysis involves using the context to make sense of the numbers. The article stresses good communication skills by highlighting the scoring...

How does your garden grow? Use proportions to help Tim answer that question. By using their understanding of proportional relationships, pupils determine the number of seeds that will sprout. They create their own linear...

Who pilfered the pin? Scholars practice measurement skills as they solve the mystery of a stolen pin. They measure length, temperature, and mass and determine which of select suspects committed the crime. During the STEM hands-on...

What a scam! Middle and high schoolers pose as journalists exposing consumer fraud. In this lesson plan, they write an article for a magazine using data collected during previous investigations (prior lessons) to defend their findings...

Seventh graders investigate theoretical and experimental probability by conducting a series of experiments with multiple trials, comparing results, combining results and making conclusions. They express probabilities as fractions,...
