From the US Census Bureau's Statistics in Schools (SIS) program comes this collection of classroom math activities designed to "engage students by using real-life data." Here, readers will find detailed, well-developed activity plans for K-12 students, each focused on a specific topic. Activities are broadly grouped into grade-level appropriate subjects: elementary grades (e.g. "Using Fractions to Compare Amusements Parks By States"), middle school (e.g. "What is a Statistical Question?"), and high school (e.g. "Applying Correlation Coefficients - Educational Attainment and Unemployment"). Individual activities indicate the specific grade level(s) they are intended for. The webpage for each activity gives a description, states the time and materials required, and also provides a list of learning objectives and a Bloom's Taxonomy teacher's note. Each lesson also includes attractively designed and downloadable PDFs of a teacher and student version of the activity. The SIS Math Activities were created by "eight content teams comprising of teachers, subject matter experts, and standards experts in K-12 education and curriculum design," and they are designed to reflect Common Core standards.
