Math Recess: Playful Learning in an Age of Disruption

“Let’s play math!” 
In the theme of recess, where a treasure chest of balls, ropes, and toys would be kept for children to play with, this book holds a deep and imaginative collection of fun mathematical ideas, puzzles, and problems. Written for anyone interested in or actively engaged in schools—parents, teachers, administrators, school board members—Math Recess by Sunil Singh and Chris Brownell shows math as a playful, fun, and wonderfully human activity that everyone can enjoy… for a lifetime! 
“Math Recess is a breathless ride!” —Kimberly Morrow-Leong, NCSM 2018 program chair, author of Mathematize It! 
“I absolutely adore this book. With clarity, power, and exuberance, Chris and Sunil spell out and make concrete what it means to play.” —James Tanton, PhD, founder of the Global Math Project 
“Here’s to the dabblers. The tinkerers. The fantasizers. The curious ones who believe math education can and should be about play. Here’s to the humanity of friendships that lead to mathematical love. Sunil Singh and Christopher S. Brownell are bold. Go, be bold with them. All are welcome.” —Mary Kemper, president of the Texas Association of Supervisors of Mathematics 
“Through rich storytelling and powerful examples, Singh and Brownell make the clear case for upending math education as we know it and replacing it with an ideology we can all embrace: Mathematics is and can be deeply learned through play.” —Denis Sheeran, author, Instant Relevance and Hacking Math 
“Disruption begins with ‘Re.’ Rather than trying to fix a broken system, it is time to reimagine a new one, and Math Recess completely satisfies my appetite for destruction.” —Brian Aspinall, educator, author of Code Breaker and Block Breaker

Curiouser and Curiouser . . . Mainstream math education over the last century has concretized an approach to mathematics that is rote, anxiety-producing, and far too focused on outcomes rather than the journey of discovery. In Chasing Rabbits, educator Sunil Singh offers an approach to mathematics that advocates getting lost, slowing down, feeling bewildered and disoriented, and even failing. Engaging with math in this way, he argues, can not only accomplish greater buy-in and enjoyment from math learners, but it can also affirm our sense of humanity and wellness overall. Singh invites the reader to explore his philosophy of mathematics through relating math to other disciplines, and to figures as diverse as MC Escher and Anthony Bourdain. Singh also delves into variously complex mathematical problems to offer concrete examples of what doing math differently looks and feels like. Mathematics, Singh demonstrates, ought to be a site not of stress and anxiety, but of wonder and joy. Endorsements "If you want to learn about what it's like to live a mathematical life by sitting around the campfire with a mug of cocoa, listening to a great storyteller who has done just that, this book is for you. It's superb. I loved it."-Keith Devlin, Stanford University "This book is a fascinating journey that illuminates the wonder, joy, and beauty of mathematics!"-Trena Wilkerson, NCTM president "Sunil Singh is a powerful storyteller who paints a vivid picture of mathematical wellness."-Mona Toncheff, NCSM president "Insightful introspections, rich rumination, and unexpected metaphors abound in this book!"-Francis Su, author of Mathematics for Human Flourishing

In Uttaranchal, tea is grown as a rainfed crop. Being dependant almost wholly on rain, its quantity and distribution are very important for growth and production of tea. In tea plantations of Kausani region of Uttaranchal, year-to-year variations in total rainfall and its distribution are significant. Total annual rainfall of 1061mm, 1354mm and 1401mm was received in 2002, 2003 and 2004, respectively (Fig. 18). During January to March 238mm, 271mm and 47mm of rainfall was received in the same order. During 2004, 82% of rainfall occurred in the months of June-August. Therefore, the rainfall distribution was not even. There was no rainfall in the month of March and total rainfall from April to May was 148mm only. Although, rainfall was highest in 2004, however, there was no rainfall in the month of March. Effect of plucking intervals on nutrient uptake In general, nitrogen, phosphorus and potassium uptake was highest in 9 days plucking interval followed by 7 and 5 days plucking intervals (Table 4.1-4.15) in both April and June. Also, uptake of all the nutrients increased in June in comparison to April.
