As young readers journey into the natural world, they will discover that numbers, patterns, shapes — and much more! — can be found in everyday plants and animals. What if animals and plants knew math, just like us? Would spiders draw pictures in their webs? Would narwhals sort blocks of ice by shape? Would insects know what’s above and what’s below? In Counting on Fall, the first title in the Math in Nature series, nature comes to life to help children in Grades K to 2 learn concepts of number sense and numeration.
