A work in progress, this FlexBook is an introduction to theoretical probability and data organization. Students learn about events, conditions, random variables, and graphs and tables that allow them to manage data.

This article discusses Project FeederWatch, a real-time citizen science project, and how elementary teachers can use this bird data to integrate math lessons and concepts.

Provides guidance on the ways to quote, paraphrase, and summarize information. Gives various reasons for paraphrasing, summarizing, and quoting various sources.

Student teams assign importance factors, called "desirability points," the rock properties found in the previous lesson/activity in order to mathematically determine the overall best rocks for building caverns within. They learn the real-world connections and relationships between the rock and the important engineering properties for designing and building caverns (or tunnels, mines, building foundations, etc.).

In this video, learn how mathematics--specifically, proportion, ratio, rate, and conversions--are used in the professional responsibilities of a registered nurse working on the surgical trauma floor. In the accompanying classroom activity, students take on the role of nursing teams, measuring vital signs, analyzing ratios, and calculating metric conversions. [4:35]

Students become familiar with the online Renewable Energy Living Lab interface and access its real-world solar energy data to evaluate the potential for solar generation in various U.S. locations. They become familiar with where the most common sources of renewable energy are distributed across the U.S. Through this activity, students and teachers gain familiarity with the living lab's GIS graphic interface and query functions, and are exposed to the available data in renewable energy databases, learning how to query to find specific information for specific purposes. The activity is intended as a "training" activity prior to conducting activities such as The Bright Idea activity, which includes a definitive and extensive end product (a feasibility plan) for students to create.

Students use real-world data to evaluate the feasibility of solar energy and other renewable energy sources in different U.S. locations. Working in small groups, students act as engineers evaluating the suitability of installing solar panels at four company locations. They access data from the online Renewable Energy Living Lab from which they make calculations and analyze how successful solar energy generation would be, as well as the potential for other power sources at those locations. Then they summarize their results, analysis and recommendations in the form of feasibility plans prepared for a CEO.

Many of today's popular sports are based around the use of balls, yet none of the balls are completely alike. In fact, they are all designed with specific characteristics in mind and are quite varied. Students investigate different balls' abilities to bounce and represent the data they collect graphically.

This learning module includes several lessons designed to illustrate best practices in school leadership and spark conversation, reflection, and new thinking in schools and districts.

Graphing can be made fun and hands-on with different real world "tools" - like snacks!

This lesson introduces the scientific method to your students through song. Students will learn the steps of the scientific method through this great song written by Kathleen Carroll. Click on the link and play it for your whole class.

Working as if they are engineers aiming to analyze and then improve data collection devices for precision agriculture, students determine how accurate temperature sensors are by comparing them to each other. Teams record soil temperature data during a class period while making changes to the samples to mimic real-world crop conditions—such as the addition of water and heat and the removal of the heat. Groups analyze their collected data by finding the mean, median, mode, and standard deviation. Then, the class combines all the team data points in order to compare data collected from numerous devices and analyze the accuracy of their recording devices by finding the standard deviation of temperature readings at each minute. By averaging the standard deviations of each minute’s temperature reading, students determine the accuracy of their temperature sensors. Students present their findings and conclusions, including making recommendations for temperature sensor improvements.

This video lesson [9:33] provides a discussion of statistical data and types of statistical questions.

Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom. Please review materials from external sites before sharing with students.

A 1st grade teacher uses a clip from Odd Squad to demonstrate measurement to her class. Students watch how Odd Squad agents use measurement to defeat the Hydroclops. They also model good mathematical practices such as being precise and persevering terms that are discussed and reinforced by the teacher. [5:09]
