This problem provides an opportunity to experiment with modeling real data. Populations are often modeled with exponential functions and in this particular case we see that, over the last 200 years, the rate of population growth accelerated rapidly, reaching a peak a little after the middle of the 20th century and now it is slowing down.

In this self-paced tutorial, examine evidence of climate change from different parts of the Earth‰Ûªs system and consider what it means to live on a planet with a dynamically changing climate. The resource includes multimedia resources such as video clips of local impacts of climate change in the Arctic and Samoa, data visualization exercise featuring digital resources on climate.nasa.gov, and an interview with NASA climate scientist Dr. Gavin Schmidt, a discussion on teaching using data, and an interactive quiz. Introduction to the Earth's Dynamically Changing Climate is the first of a series of ten self-paced professional development modules providing opportunities for teachers to learn about climate change through first-hand data exploration. Activities and resources that can be employed in the classroom are featured.

This task lets students explore the differences between linear and non-linear functions. By contrasting the two, it reinforces properties of linear functions. The task lends itself to an extended discussion comparing the differences that students have found and relating them back to the equation and the graph of the two functions.

Introductory Statistics is intended for the one-semester introduction to statistics course for students who are not mathematics or engineering majors. It focuses on the interpretation of statistical results, especially in real world settings, and assumes that students have an understanding of intermediate algebra. In addition to end of section practice and homework sets, examples of each topic are explained step-by-step throughout the text and followed by a Try It problem that is designed as extra practice for students. This book also includes collaborative exercises and statistics labs designed to give students the opportunity to work together and explore key concepts. While the book has been built so that each chapter builds on the previous, it can be rearranged to accommodate any instructor’s particular needs.

Today, we're going to begin our discussion of Big Data. Everything from which videos we click (and how long we watch them) on YouTube to our likes on Facebook say a lot about us - and increasingly more and more sophisticated algorithms are being designed to learn about us from our clicks and not-clicks. Today we're going to focus on some ways Big Data impacts on our lives from what liking Hello Kitty says about us to how Netflix chooses just the right thumbnail to encourage us to watch more content. And Big Data is necessarily a good thing, next week we're going to discuss some of the problems that rise from collecting all that data.

In this activity students use log tapes and base-two slide rules as references to graph exponential functions and log functions in base-10 and base-2. Students discover that exponential and log functions are inverse, reflecting across the y = x axis as mirror images. This is activity E2 in the "Far Out Math" educator's guide. Lessons in the guide include activities in which students measure, compare quantities as orders of magnitude, become familiar with scientific notation, and develop an understanding of exponents and logarithms using examples from NASA's GLAST mission. These are skills needed to understand the very large and very small quantities characteristic of astronomical observations. Note: In 2008, the GLAST mission was renamed Fermi, for the physicist Enrico Fermi.

Dominoes have become a staple in most primary classrooms. They build upon dice patterns and are often used to model decomposition of numbers, building student knowledge of addition facts. They are an excellent manipulative for primary students to use and these are some examples of how students might use dominoes in the math center. Try these domino games with students to improve math skills and number recognition. Encourage students to play these games at home with their families, using real dominoes or paper copies.

"Provided below are links to a series of free booklets to assist mathematics teachers of Grades 4, 5, 6.
These books will stimulate interest, competence, and pleasure in mathematics among students. The activities are appropriate for either individual or group work. Collaborative activities allow students to construct their own meanings and understanding. This emphasis, plus the "Extensions'' and related activities included with individual activities/projects, provide ample scope for all students' interests and ability levels. Related "Family Activities'' can be used to involve the students' parents/caregivers.
Each book is intended to occupy about one week of daily classes. However, teachers may choose to take extra time to explore the activities and extensions in more depth. The books have been designed for specific grades, but need not be so restricted. Activities are related to curriculum expectations."

In this activity, students graph second and third order functions, discovering an inverse relationship between squares and square roots and between cubes and cube roots. Students graph these functions on both linear grid (evenly spaced numbers), and a log-log grid (evenly space exponents). Graph lines that curve on linear grids transform into straight lines on the log-log grids, with slopes equal to their exponential powers. This activity is activity E3 in the "Far Out Math" educator's guide. Lessons in the guide include activities in which students measure, compare quantities as orders of magnitude, become familiar with scientific notation, and develop an understanding of exponents and logarithms using examples from NASA's GLAST mission. These are skills needed to understand the very large and very small quantities characteristic of astronomical observations. Note: In 2008, GLAST was renamed Fermi, for the physicist Enrico Fermi.

When students plot irrational numbers on the number line, it helps reinforce the idea that they fit into a number system that includes the more familiar integer and rational numbers.

An interactive applet and associated web page that show the behavior of irregular polygons. The applet shows initially an irregular convex polygon. All vertices are draggable and when dragged show that this has no effect on any other vertex. The polygon can be made regular, and the number of sides changed between 3 and 99. Applet can be enlarged to full screen size for use with a classroom projector.

In this activity, students survey other people to find out their thoughts about life beyond Earth and compare their ideas with visitors to the Cosmic Questions exhibit. Students can also analyze their survey data to see whether there is any variation or patterns in answers from men and women or people of different ages. To do this, students will need to design their own method for tracking demographic data. This activity is part of the "Cosmic Questions Educator's Guide" that was developed to support the Cosmic Questions exhibit. Activities in the guide can be used in conjunction with or independently of the exhibit.

This activity uses Dr. Drake's framework to have students consider the implications of each term and make their own estimates of life in the Milky Way galaxy.åÊThis activity is part of a guide that was developed in conjunction with the Cosmic Questions exhibit and complements a museum visit. However, the activities can also be used independently. The format is flexible, and educators can pick and choose the materials that are most appropriate for their students.

An interactive applet and associated web page that demonstrate isosceles triangles (two sides the same length). The applet presents a triangle where the user can drag any vertex. As the vertex is dragged the others move automatically to keep the triangle isosceles. The angles are also updated continuously to show that the base angles are always congruent. Applet can be enlarged to full screen size for use with a classroom projector.

An interactive applet and associated web page that provide step-by-step animated instructions on how to construct an isosceles triangle with given base and altitude using only a compass and straightedge. The animation can be run either continuously like a video, or single stepped to allow classroom discussion and thought between steps. Applet can be enlarged to full screen size for use with a classroom projector.
