# STatistics Education Web (STEW)

One of the goals of the American Statistical Association is to improve statistics education at all levels. Through the STatistics Education Web (STEW), the ASA is reaching out to K-12 mathematics and science teachers who teach statistics concepts in their classrooms. STEW is an online resource for peer-reviewed lesson plans for K-12 teachers. The web site is maintained by the ASA and accessible to K-12 teachers throughout the world. Statistics and probability concepts are included in K-12 curriculum standards, in particular the Common Core State Standards, and on state and national exams; however, few K-12 teachers have formal training or applied experience with statistical concepts. STEW lesson plans identify both the statistical concepts being developed and the age range appropriate for its use. Lesson Plans Grades K - 5 Grades 6 - 8 Grades 9 - 12

NCTM Illuminations Looking Back and Moving Forward Pre-K-2, 3-5, 9-12 This final lesson of the unit reviews the work of the previous lessons through a variety of activity stations, one of which involves using an interactive graphing tool. Students model with buttons and record addition and subtraction. Counting Embedded Figures Students look for patterns within given data and form generalizations for the problem, thereby sharpening the algebraic skills of the students. Building Connections This lesson focuses on having students make connections among different classes of polynomial functions by exploring the graphs of the functions. Counting Embedded Figures This grades 7-12 activity allows students to look for patterns within the given data. Explorations with Chance In this lesson, students analyze the fairness of certain games by examining the probabilities of the outcomes. Exploring Linear Data Students model linear data in a variety of settings that range from car repair costs to sports to medicine.
