Teach kids to count and read at the same time Know Your Numbers: Nature introduces early readers to numbers by paring them with simple sentences about nature. Beautiful photos and graphics tie the written, numeral, and visual forms of each number together. For instance, one page has a picture of 16 seashells, a sentence about them, and four different ways to see the number sixteen.
