They have made a very serious decision-they are going on an adventure. All by themselves, just the two of them. Dad might offer a suggestion or two, but this expedition is just for them! Of course, they will have to bring coffee and pickles and blankets and a cozy tent. And, just in case, a jump rope to use as a lasso. They set up camp in the lee of a small mountain (or, in their backyard) and get ready for an evening of fun. But when the pickles are gone and the mosquitoes come out, what's to be done? The Grand Expedition is the quietly comic story of two kids and their dad and the everyday adventures that make life great.

In this innovative book, Emma Adb?ge encourages children to get outside, where they can have fun interacting with the natural world while learning math. Adb?ge has created twenty-two outdoor activities, organized by season. Through play, children will learn about numeracy and arithmetic, as well as math concepts such as shapes, time, greater/less than, even and odd numbers, patterns and grids. The activities have simple-to-follow instructions and are accompanied by adorable illustrations that provide clear visual demonstrations. The natural materials required --- stones, pinecones, snowballs, worms --- are easy to find in many environments. Supplementary spreads introduce the numbers 1 to 10 and further explore addition/subtraction and multiplication/division, with simplified explanations and illustrated examples. Studies have shown that learning outdoors helps kids retain information and skills, and that physically active children perform better in a variety of subjects --- including math. This book could be used alongside other math coursework all school year, since the activities have direct curricular applications. While the thrust of the book is math, there are also science lessons here, particularly regarding the properties of nature and how things change during the four seasons. Many of the activities can be done in pairs or groups, promoting teamwork and cooperation. A list of activities in the back matter indexes the activities and categorizes them by the math skills they develop.
