"Contexts for Learning Mathematics" series is designed to support a conceptual understanding of essential mathematical ideas, strategies and models. Each unit provides a two-week sequence of investigation, minilessons, games, and other contexts for learning. The series' 18 classroom-tested units are organized into grade-appropriate levels.

In New York’s Central Park, some of the playgrounds constructed as part of the midcentury experimental “playground revolution” still remain. In Central Park's Adventure-Style Playgrounds, Marie Warsh tells the engrossing history of these playscapes built in the 1960s and 1970s, exploring their connections to the art, recreational design, urbanism, grassroots movements, and child-development theories of the period. She further details the Central Park Conservancy’s efforts decades later to preserve and renew these playgrounds. So-called adventure-style playgrounds featured interconnected forms including pyramids, mounds, and steps, and basic materials such as water and sand, encouraging new levels of creativity and interaction. By the end of the 1970s, ten of Central Park’s twenty-two existing playgrounds—formerly paved, sterile, standard-equipment-filled lots dating to the 1930s—had been transformed according to the new design ideals. With time, deterioration prompted concerns about safety, and much of the equipment was removed. However, community interest led the Central Park Conservancy to update and preserve the playgrounds that remained in the park. Building on successful aspects of the playgrounds, designers incorporated new technologies, materials, and equipment that reflect contemporary ideas about children’s play and approaches to urban park management. They also developed strategies to better integrate them into the landscapes of the park. Today, Central Park’s adventure-style playgrounds represent significant works of renewed modern landscape architecture as well as models for new thinking about playground design.

A new way forward for sustainable quality of life in cities of all sizes Strong Towns: A Bottom-Up Revolution to Build American Prosperity is a book of forward-thinking ideas that breaks with modern wisdom to present a new vision of urban development in the United States. Presenting the foundational ideas of the Strong Towns movement he co-founded, Charles Marohn explains why cities of all sizes continue to struggle to meet their basic needs, and reveals the new paradigm that can solve this longstanding problem. Inside, you’ll learn why inducing growth and development has been the conventional response to urban financial struggles—and why it just doesn’t work. New development and high-risk investing don’t generate enough wealth to support itself, and cities continue to struggle. Read this book to find out how cities large and small can focus on bottom-up investments to minimize risk and maximize their ability to strengthen the community financially and improve citizens’ quality of life. Develop in-depth knowledge of the underlying logic behind the “traditional” search for never-ending urban growth Learn practical solutions for ameliorating financial struggles through low-risk investment and a grassroots focus Gain insights and tools that can stop the vicious cycle of budget shortfalls and unexpected downturns Become a part of the Strong Towns revolution by shifting the focus away from top-down growth toward rebuilding American prosperity Strong Towns acknowledges that there is a problem with the American approach to growth and shows community leaders a new way forward. The Strong Towns response is a revolution in how we assemble the places we live.

From building blocks to city blocks, an eye-opening exploration of how children's playthings and physical surroundings affect their development. Parents obsess over their children's playdates, kindergarten curriculum, and every bump and bruise, but the toys, classrooms, playgrounds, and neighborhoods little ones engage with are just as important. These objects and spaces encode decades, even centuries of changing ideas about what makes for good child-rearing--and what does not. Do you choose wooden toys, or plastic, or, increasingly, digital? What do youngsters lose when seesaws are deemed too dangerous and slides are designed primarily for safety? How can the built environment help children cultivate self-reliance? In these debates, parents, educators, and kids themselves are often caught in the middle. Now, prominent design critic Alexandra Lange reveals the surprising histories behind the human-made elements of our children's pint-size landscape. Her fascinating investigation shows how the seemingly innocuous universe of stuff affects kids' behavior, values, and health, often in subtle ways. And she reveals how years of decisions by toymakers, architects, and urban planners have helped--and hindered--American youngsters' journeys toward independence. Seen through Lange's eyes, everything from the sandbox to the street becomes vibrant with buried meaning. The Design of Childhood will change the way you view your children's world--and your own.
