What if animals and plants knew math, just like us? Would flowers bloom in patterns? Would raindrops fall in rhythm? Would birds balance evenly on branches? In Sorting through Spring , the second title in the Math in Nature series, nature comes to life to help children grasp concepts of patterning, sorting, data management, and probability. This interactive, poetic, and artful picture book series is a non-intimidating and enticing way to introduce math to kids -- they will laugh, use their imaginations, and learn through activities inspired by the books.
